Hi, I am currently running FF 91.0.2 on Xubuntu 18.04 and recently icons are appearing abnormally on both Firefox internal web pages such as: about:preferences#privacy (see 1st pic),

as well as on external web pages such as: YouTube https://www.youtube.com/watch?v=1zrg2Vanfco (see 2nd pic)

I have re-installed FF and imported my old profile but no difference. I have tried to restart FF in Troubleshoot mode but it doesn't resolve the problem, what to do?


EDIT: Solution provided by cor-el solved the problem with Firefox internal pages. The problem with YouTube "new" black-and-white icons seems to be something else as these appear with other browsers too.

Issues with checkboxes can happen if you have set "browser.proton.enabled = false" on the about:config page to disable Proton.

In Firefox 91+ you can no longer disable Proton and revert changes that come with this design via "browser.proton.enabled = false" on the about:config page. Best in Firefox 91 is to set browser.proton.enabled at its default value true as the false setting can cause issues with checkboxes.

In Firefox 91+ you need to use code in userChrome.css to override changes coming with the Proton design.

WARNING: This script is not provided by Mozilla and is not officially supported Creating a userChrome.css file and other ways of customizing Firefox that are not exposed in the interface are there for developers, not end-users. If it were intended for end-users, you would see a menu option or checkbox; you wouldn't have to hack a text file in a hidden location.

What this means is that even though the functionality you want is no longer supported, a third-party has found a way to do it using the CSS file. If it breaks in new versions, you will need to contact the person who provided the script.
