Firefox 83 alleviates the need for HTTP to HTTPS redirect add-ons such as HTTPS Everywhere and HTTPZ, however the feature is not enabled by default. Here's how to enable it...
If you're not running a custom user.js file (if you don't know what that is, you're probably not), enter
in the address bar and in the filter field at the top enter
. Set that preference to 'true' and you're done.
If you are running the 'arkenfox' user.js, you should have a user-overrides.js where you keep your personal preferences. In this case, just add the
preference to it:
If you use your own user.js, you already know what to do.
This preference will force all websites to use an encrypted connection (HTTPS). In the case where that isn't possible, Firefox will display a warning from which you can temporarily override the redirect and load the website without using encryption. If you always want to allow the unencrypted connection, you can add an exception for the site by clicking the lock icon in the address bar.
While the new functionality isn't as transparent as with the HTTPZ add-on, it's a welcome and overdue addition in my opinion.
