Firefox Tweaker 2.4.2 released for Firefox 78

With preparation for Firefox 78 release landing really soon, I’ve prepared updated version of Firefox Tweaker that uses new “ui.prefersReducedMotion” parameter to turn off the moronic oversized URL bar introduced with Firefox 75.

This means all the old parameters used till this point are now obsolete. I’ve also removed CSS method from Firefox Tweaker 2.4.2 in favor of this reduced motion thing. Unfortunate downside of Mozilla dicking around so much with this thing is that bunch of tweaks need to be left behind inside prefs.js because it complicates things removing them correctly as means of cleanup. I believe performance penalty for leaving them there is immeasurable. As people are reinstalling systems or Firefox browser and new versions of Firefox Tweaker (after version 2.4) won’t be inserting them anymore, it’ll eventually get purged from systems on its own.

You can clean things up yourself deleting/reverting the following entries in about:config:

  • browser.urlbar.update1
  • toolkit.legacyUserProfileCustomizations.stylesheets

Deleting custom user CSS style sheet:

Use “Open Firefox profile folder” function in the Firefox Tweaker and delete the “chrome” folder which contains “userChrome.css” file
