background
I recently updated firefox to version 91, but the firefox team disabled the about:config tweaks of browser.proton.enabled = false
without adding a feature to disable proton tabs
solution
A search resulted in the following question
https://support.mozilla.org/en-US/questions/1346685#answer-1434276
The answer suggested using userchrome tweaks from the userchrome.org guide for disabling proton styling
Firefox 89+ – Styling the New Proton UI
setting up userchrome
I followed the instructions and adapted them from this guide
https://www.userchrome.org/how-create-userchrome-css.html
If you run into issues with my guide, you can always go back and read the original for a in depth explanation
- go to
about:support
- look for your directory location, and hit the open directory tab. I edited my directory to say {your-directory}
- make a new folder called
chrome
inside of your profile directory - create or generate a new userchrome.css file. If you use the generated file, make sure to rename it to userchrome.css.
- place the userchrome.css file into the
chrome
folder - Now we will enable userchrome tweaks. Go to
about:config
pastetoolkit.legacyUserProfileCustomizations.stylesheets
in the search box, and set the variable to true. - Restart firefox. Go to
about:profiles
, clickRestart Normally...
- Congratulations, proton tabs should be disabled.
