Content update: Firefox Configuration Guide for Privacy Freaks and Performance Buffs

I updated the Firefox Configuration Guide for Privacy Freaks and Performance Buffs with some info regarding uMatrix breaking file downloads in Firefox. I found and solved this issue before but apparently failed to document it and so i had to repeat the process. Here's what was added to the guide:

One caveat with uMatrix is that it will break some downloads when right-clicking a link and selecting the 'Save Link As...' context menu item. In some cases an error dialog will be presented that may state "The download cannot be saved because an unknown error occurred.". If you open the uM logger and try the download again, you'll find that uM is blocking something and often this seems to be an 'other' network request ('other' requests are requests that are not associated with a tab). There are a few ways to remedy the situation:

  • temporarily (or permanently) allow the 'other' request from the uM logger tab and try the download again
  • temporarily (or permanently, but not recommended) allow the 'other' request globally from the main UI pop-up
  • drag the link to your desktop
