Hi, I tried to reproduce this issue but I'm not sure I fully understand it, The steps are :

1. Start Firefox with a fresh new profile.
2. Set the Bookmarks Toolbar to be displayed.
3. Open the about:support in order to find the profile folder.
4. Create the userChrome.css file that contains:
   #PersonalToolbar {visibility: collapse !important;}
   #navigator-toolbox:hover > #PersonalToolbar {visibility: visible !important;}
5. Set toolkit.legacyUserProfileCustomizations.stylesheets=true in about:config.
6. Restart the Firefox Browser.

Expected results should be that the Bookmarks toolbar is hidden.
Actual Results the Bookmarks toolbar is still displayed.

Did this functionality work before 68.0.1 ?
Can you retry this issue in Safe Mode? you can find the steps here: https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode
Also can you please try our latest Nightly and let us know if the issue still occurs there as well. You can find the build here: https://nightly.mozilla.org/

Thanks for working on this.

It should work, see below

The problem is I can't make UserChrome.css work at all in 68.0.1. I tried the example userChrome.css of the above and it didn't work either. I put it into profile folder and profile/chrome folder, neither worked.

I tried the nightly and safe mode, neither worked.

I will set the component for it and maybe one of our developers can take a look and they will know more about this issue. Thanks for taking the time to report this problem.

I tested this and the preference works for me. In your steps to reproduce, you're missing the step that the userChrome.css file needs to be within a directory (create this if it doesn't exist) called "chrome".

I had to put the "chrome" directory in the "roaming" profile directory, also known as the "root directory" for the profile.

See the steps at http://kb.mozillazine.org/index.php?title=UserChrome.css&printable=yes

That is, if putting userChrome.css into chrome folder, it worked.
