Firefox Extensions

Firefox Extensions – My Picks

Mozilla Firefox is a popular, free, open source web browser that is extremely configurable and easy to use. Somewhat bare out of the box however, its functionality is easily extended with add-ons (or extensions, if you prefer), of which there are many thousands.

With so many add-ons, most of which are free, the casual user might be tempted to install a large number of them, however i would highly recommend installing only the add-ons you really like or need since the potential to break things increases with every add-on that is installed. Not only can add-ons conflict with each other, they can also conflict with a native Firefox behavior.

Another issue that should be considered is unethical add-on developers that sometimes package unnecessary components which may include provisions for tracking your web activities or other behavior that is not relevant to the primary function of the add-on. Although Mozilla limits what a developer is allowed to do, user tracking is permitted and so i would highly recommend that you take the following precautions before installing any add-on:

  • Install the Extension Defender add-on (see below) to help protect against malicious extensions
  • Be very wary of any add-on which is packaged in the form of a tool-bar! Many/most of these contain 3rd party malware and/or spyware which is employed by the developer to monetize their add-on.
  • Be very wary of any add-on that has a privacy policy! Some of these are fine, but many are not, so be sure to read the privacy policy if one is available.
  • Check the user reviews to see how well an add-on is liked and be wary if it is rated at 3 or less stars, or not rated at all.
  • Even if the add-on is rated 4 or more stars, check the comments of the people that gave it the lowest rating to see if their gripe may be legitimate. Several very popular add-ons contain unwanted functionality such as user profiling/tracking including Abduction, a screen capture utility; Quick Locale Switcher, a language switcher; FasterFox Lite, a largely useless utility which claims to speed-up Firefox; BlockSite, a content blocker; Google’s Search By Image, a reverse image search utility, and others.
  • Visit the developer website if one is available and see what kind of content is there. Look for marketing hype and be wary of dot com domains. I would also suggest being weary of developers that provide neither a website where the add-on code is hosted nor an email address for support requests.

My favorite Firefox add-ons

Last updated: 30-APR-2016

There are a few very popular add-ons that are absent here, including NoScript and Adblock Plus (or Adblock Edge). While this may seem odd to some, the functionality offered by these extensions is largely covered by uBlock Origin and uMatrix. See my Firefox Configuration Guide for Privacy Freaks and Performance Buffs article for more information.

Name Description Notes/Caveats
Add to Search Barbuildenhance

Add to Search Bar

Add to Search Bar is an extension that makes it super easy to add almost any search engine to the Firefox Search Bar.
BetterPrivacy

buildsecurityprivacy

Better Privacy

There are several types of cookies and opting to block cookies from the Firefox privacy options will not block them all. Better Privacy can deal with another type of cookie called ‘Local Shared Objects’, or so-called Flash cookies which are set by the Adobe Flash Player plug-in. Better Privacy is a set-it-and-forget-it extension for most people, though there are options to protect specific LSO’s from being deleted. Since most popular video sites now use HTML5 to play video instead of the Adobe Flash Player plug-in, there is less of a need to have Flash installed at all. To help alleviate the need for Flash, and therefore Better Pivacy, see the EmbedUpdater add-on below. Note that this add-on is not required if you do not have the Flash plug-in installed I suppose it may be possible to break certain websites if they rely on Flash cookies, however i have not experienced this.
BetterStop

enhance

BetterStop

BetterStop extends the functionality of the Esc key (or Stop button) with options to stop page loading and network activity. Very simple and transparent with no added toolbar icons or fuss.
Beyond Australis

buildenhance

Beyond Australis

I use Beyond Australis only for its ability to update the text in the search bar when you switch tabs, which is a great feature when combined with the SearchWP add-on below. Others may find it more useful.
Classic Theme Restorer (Customize UI)

enhancefix

Classic Theme Restorer

Not happy with the new Australis interface for Firefox? I don’t blame you, but if you want the latest gizmo’s and security fixes, you’re stuck with it. Unfortunately, yet another add-on is necessary to re-add the functionality that the wizards at Mozilla think you don’t need, and that add-on is Classic Theme Restorer. In addition to its many settings for manipulating the appearance of Firefox, CTR also makes is easy to disable some of the “features” which rely on 3rd party services, including the Hello and Pocket features.
Clean Links

enhancesecurityprivacy

Clean Links

Clean Links is a great add-on that has replaced two of my former favorites — Redirect Cleaner (extinct) and PureURL — as it does the job of both. Clean Links can remove junk from URL’s, such as Google Analytics and other tracking mechanisms, as well as any other content you wish to remove. It also cleans redirect links so you are transported directly to your destination without having to go through a middleman. Lots of options make it nicely customizable without going over the top. If you do not like being tracked across the web, this add-on is a must-have. Basic knowledge of regular expressions is required to customize some options. This add-on can break some website functionality, but white-listing a domain is very easy.
Decentraleyes

securityprivacy

Decentraleyes

Decentraleyes is a privacy enhancing add-on that has the additional benefit of decreasing the load time for many web pages. It does this by loading several common JavaScript resources locally instead of having to fetch them from the web server. Could potentially break some web sites, though it is possible to white-list affected domains.
Easy Copy

build

Easy Copy

The highly configurable Easy Copy add-on provides the ability to copy various content, such as hyperlink text, the page titles, excerpts and more, in various formats. For example it makes it easy to copy both a page title and link which is formatted for posting on a forum.
EmbedUpdater

buildsecurityprivacy

EmbedUpdater

While many popular video websites now serve video using the HTML5 format, many videos that are embedded on 3rd party sites do not. EmbedUpdater aims to solve that problem, thus reducing the need to have the ever-vulnerable Adobe Flash Player plug-in installed.
Exif Viewer

build

Exif Viewer

Exif Viewer does nothing more than allow you to view the EXIF metadata stored in many JPEG images, including the camera and exposure info and, when available, the GPS location of the image.
Extension Defender

buildprivacysecurity

Extension Defender

Extension Defender is an install-it-and-forget-it add-on which simply checks your extensions against a list of those that contain unwanted “features”, such as user tracking or malware.
FireFTP

build

FireFTP

FireFTP ia a popular and reasonably well-rounded FTP client for Firefox. The developer also offers an SSH client as well. It has its quirks and i particularly don’t like the way you navigate local directories as it doesn’t display all the drives as Windows Explorer does, but rather only the last selected drive.
Flagfox

build

Flagfox

Flagfox is a very cool, mufti-purpose extension. At its root it simply displays the flag of the country for the website you’re visiting in the Firefox address bar (now called the “Awesome Bar”), but left and right clicking on the icon reveals many more options. For instance, right clicking the icon opens a customizable context menu from which you can select things like doing a “WhoIs” look-up for the current domain, ping, trace route, geo-locate, W3C validation, translations and even shorten the URI in the address bar using services like bit.ly or Tiny. Many more options are available if you want and you can even add your own. Would be nice if the developer offered a tool-bar button instead of forcing the icon to display in the address bar only. If you choose to display the menu icons, they are not stored locally and have to be fetched the first time you open the menu
Greasemonkey

build

Greasemonkey

The new Greasemonkey has replaced Scriptish (which replaced an earlier version of Greasemonkey) as my favorite user script extension. Greasemonkey is for running user created scripts which are typically used to change how a website functions and/or looks. Some of the most popular scripts allow you to download videos from sites like YouTube, or enhance the functionality of sites like Facebook and Google. You can even find some proof of concept scripts for defeating CAPTCHA’s, though they don’t appear to be fully baked just yet. For a selection of scripts that i personally find useful, see the bottom of this page. Installing user scripts is a security and stability risk! While this holds true for extensions as well, scripts are generally not scrutinized to the degree extensions are when download from Mozilla. Some sites that host scripts do not preform any security checks at all. Be sure to read the feedback from others, as well as the history of the developer, before installing any script.
Hide Caption Titlebar Plus

buildenhance

Hide Caption Titlebar Plus

Hide Caption Titlebar Plus makes it easy to hide the Firefox window title bar, especially on Linux. It also offers new ways to accomplish other common tasks, as well as additional functionality.
Image Search Options

build

Image Search Options

So you’re working on your website and you need an image. You find one you really like, but maybe the quality is crappy or it’s too small. What to do? Right click and use a reverse image search provider to find a better version of the same image (my personal favorite is TinEye). With Image Search Options, you can do a reverse image search using any or all of a large number of service providers and even add your own.
Link Alert

build

Link Alert

Link Alert simply provides a visual indication of the target of a link when you hover your pointer over the link. Want to know if the link target is a PDF, EXE, audio or ZIP file? Want to know if the target is a new window, or a JavaScript link? Link Alert can do all this and more. You can also add your own alerts.
Menu Wizard

build

Menu Wizard

Replacing the limited Menu Filter and outdated Menu Editor add-ons is Menu Wizard, a fantastic new add-on for removing, adding and rearranging the menu items for various Firefox context menus, which can become quite unruly after installing a bunch of extensions. It also handles the browser’s hot-keys.
NewsFox

build

NewsFox

If you read a lot of syndicated feeds (RSS/ATOM) NewsFox is, in my opinion, the very best extension for reading and managing your feeds within Firefox, even given the caveats i have listed. It offers a lot of configuration options for reading, organizing and marking the status of feeds, and it has a clean, intuitive, customizable, 3 pane interface. NewsFox can briefly hang the Firefox GUI while checking feeds. I don’t like that you cannot create sub-folders within a folder.
OmniSidebar

buildenhance

OmniSidebar

Although i have used the more popular All-in-One Sidebar (AiOS) for quite a long time, i now prefer OmniSidebar. Although it is somewhat less polished in some areas and lacks a few small features of AiOS, it is feels lighter and works very well. You can also display two sidebars with it; one on the left of your display and another on the right. I especially like the sidebar switch that is used to toggle the opening and closing of the sidebar since it does not eat any screen real-estate.
Resurrect Pages

build

Resurrect Pages

Page not found? Want to see what a web page looked like 10 years ago? Resurrect Pages can look up the current web page or hyperlink in one of several places that archive web content including the Internet Archive and Google Cache.
Save URL to Wayback Machine

build

Save URL to Wayback Machine

Save URL to Wayback Machine makes it super easy to archive a webpage by storing it on either the Internet Archive or archive.is. Personally i prefer the latter since it does not respect the robots.txt standard which basically means that, once you archive something, it’s permanent.
ScrapBook

build

ScrapBook X

A fork of the original ScrapBook extension, ScrapBook X is a very handy tool for storing scraps of text, web pages or images that you want to save. I use it often when i research subject matter, such as when i wrote the NPR article. You can import, combine and export your Scrap Book, including exporting as HTML. If you need more power, try Zotero.
Scroll Up Folder

build

Scroll Up Folder

Replacing Smart Text / Smart Location is Scroll Up Folder, a fairly nice little extension which makes it super simple to navigate within a domain, going up or down the URL structure. For example, you can go from subdomain.example.com/dir/?=param1
to any of the following:
subdomain.example.com/dir/
subdomain.example.com
example.com
While there are several other add-ons that offer similar functionality, Smart Text is the only one i have found that a) does not require a toolbar/address bar button or context menu, b) segments URL parameters and c) handles sub-domains properly.
Search Site

build

Search Site

Search Site is a great little extension that adds another icon in the right side of the Search Bar that, when clicked, will search only the current website for your search terms. Though there are others like it, i particularly like the way it’s integrated. If another icon is too much for you, you can hide it and just Ctrl+Enter instead.
SearchWP

build

SearchWP

One of those brilliant little extensions whose functionality should be built-in in my opinion, SearchWP simply transforms the words in the Search Bar to clickable buttons. Clicking on a word button will take you to the point in the page where the word is located. It was particularly useful when installed along with the Conform SearchBox extension, however the latter is pretty broken and unmaintained.
Status-4-Evar

buildfix

Status-4-Evar

Mozilla’s continuing trend of dumbing down the browser to an infants level has, once again, pissed off a lot of people, this time when they removed the status bar. Status-4-Evar restores the absent functionality and adds some cool new toys as well. Even if you don’t use the status bar, Status-4-Evar is still very useful if you want to move browser elements, such as the pop-up of the hovered link address or network status, to another location.
uBlock

buildsecurityprivacy

uBlock Origin

uBlock Origin is a superior content filter that replaces all other content/ad blockers for me including Adblock Plus/Edge, NoScript, Policeman and several others. It is capable of using the same filtering lists as Adblock Plus/Edge as well as many more filter lists that the others cannot use. Two of the most welcome differences with uBlock Origin is that it does not slow the loading time for Firefox to any noticeable degree and it uses far less memory then the Adblock derivatives. Another major advantage over the other Adblock extensions is that it can block both 1st and 3rd party requests for images, scripts and frames. See my Firefox Configuration Guide for Privacy Freaks and Performance Buffs article for more information regarding uBlock Origin. Lastly, note that there are two versions of uBlock; uBlock and uBlock Origin. I highly recommend that you use uBlock Origin which is written by the original developer, Raymond Hill. As with any content filtering extension, uBlock Origin has the potential to break website functionality until it is configured correctly
uMatrix

buildsecurityprivacy

uMatrix

uMatrix, also by Raymond Hill, is similar to uBlock Origin in that it is also a content blocker, the main difference being that it offers more granular control over blocking various resources including cookies, CSS, images, plug-ins, scripts, XHR, frames and more. In my case i use uBlock Origin as an install-it-and-forget-it solution for blocking mostly ads and malware domains, while i use uMatrix to block the aforementioned resources. It is perfectly fine to use both together, but i would suggest reading my guide, Firefox Configuration Guide for Privacy Freaks and Performance Buffs, for information on how to configure them to get the most out of each one. As with any content filtering extension, umatrix has the potential to break website functionality until it is configured correctly

Greasemonkey scripts

Some Greasemonkey scripts which i find useful:

Linx Amender – Linx Amender is a powerful tool that is well-suited to those who are not quite able to write their own Greasemokey scripts, but are knowledgeable about HTML and CSS and want to alter the appearance and/or functionality of a websites. From the official description; “Linx Amender is a powerful script that allows you to alter the page content using regular expression and rules.” There is a lot you can do with this script, though i am currently using it only to make a few changes to various websites, including http to https redirects, manipulating YouTube, removing link redirections and tracking parameters and a couple other things. Among its other capabilities, Linx Amender allows you to write JS scripts, so you can use it to write your own extensions essentially, as well as replace other user scripts.

Google Hit Hider by Domain – This is a very nice and polished script that simply allows you to remove unwanted results from a Google search, or other search providers that use Google results, such as Startpage and DuckDuckGo.

ViewTube – One of the better scripts for dealing with YouTube stupidity, this script prevents auto-play and allows you to view videos in a variety of formats, including HTML5 or by using an external player such as VLC. ViewTube also makes it easy to download video files in all of the various formats and levels of quality it can detect. ViewTube works with many video sharing sites other than YouTube and can be extended to work with even more using the ViewTube+ add-on which you can download from the home page.

Doing it without an add-on

Enhancing privacy and security

See my Firefox Configuration Guide for Privacy Freaks and Performance Buffs article for more information.

Smooth scrolling

See my Firefox Scroll Tweak tutorial for how to enable dynamic, silky smooth scrolling without using an extension.

Copying text without formatting

Sometimes you may want to copy text without the added HTML markup. While i am not aware of any way to do this without an extension, you can do the next best thing, which is paste the text without the formatting. To do this, simply paste using Ctrl+Shift+V instead of Ctrl+V. This works on Windows and Linux.

Giving back

If you like an add-on, or any other free software, please donate to the developer. Trust me when i tell you that most developers of free software usually receive nothing, or next to nothing for all their hours of hard work and the support they provide. Developers are usually very appreciative of a donation regardless of how small it may be.

4 thoughts on “Firefox Extensions – My Picks

    1. hi Shadylayman – funny you mention uBlock as i looked at it a short while ago, but too quickly to realize it’s advantages

      uBlock will certainly replace both Adblock Edge and Element Hiding Helper as it is a much more capable extension in every way

      thanks for mentioning it :)

      regarding HTTP UserAgent cleaner however, that one stays – it covers a whole lot more than just the user-agent string

  1. For some time now, I’ve been using these Greasemonkey scripts: Anti-Adblock Killer 8.1, AdsBypasser 5.24.0 (gets around the very annoying Ad.fly, Linkbucks, etc. pages), and Ad Host Cleaner 1.3.4 — the last version I could find of this. Its motto was “Bye Bye Download Accelerator/Manager”, and for awhile it thwarted file hosts that wanted to force you to accept an .Exe file version each time, rather than a standard .Rar piece of an archive. Of course, this is very bad practice, easily giving a free ride to malware or who knows what. However, Ad Host Cleaner seems to no longer be effective. I was hoping you might know of some later script or extension (for FireFox or for Chrome) that still provides control over this ?

    1. hi Gene
      i do not know of an extension for bypassing the garbage at download sites specifically, but i’m sure that some exist – go to the Mozilla Add-ons site and search for “skip” or “bypass” along with “downloads” – i know i have seen some and even used one at one point, but i cannot recall the names

      as for the anti-ad-block part of your question, i am sure there are other GM scripts available – you might also want to check out uBlock which offers this capability along with being a general content blocker – see the uBlock section of my article, Firefox Configuration Guide for Privacy Freaks and Performance Buffs
