Trying to recover from a hard drive crash. Had to buy a new desktop with Windows 11 Pro (looking to be a bad move). I downloaded/updated to Firefox 126.0 (maybe also looking to be a bad move).

Have my last "working" userChrome file (it took me weeks to perfect this to my needs).

I am looking for: C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Profiles\<profile>\

but there is no "AppData" folder. And there is no existing userChrome.css file, anywhere!

Is the functionality I am looking for a thing of the past?

Is Firefox not completely supported by Windows 11?

If so, what is the last version of Firefox that will still support userChrome.css?

No, it's still supported.

You need to place userChrome.css and userContent.css in the chrome folder in the Firefox profile folder.

You can use the button on the "Help -> More Troubleshooting Information" (about:support) to go to the current Firefox profile folder or use the about:profiles page (Root directory).

In Firefox 69 and later you need to set this pref to true in about:config to enable userChrome.css and userContent.css.

I see nothing here about userContent.css much less userchrome.css.

What am I missing?

Possibly nothing in case you have no purpose for using userChrome.css. I'm not sure why you asked this question.

Both userChrome.css and userContent.css do not exist by default and you need to create the chrome folder in the Firefox profile folder and within this folder userChrome.css/.userContent.css if you want to customize Firefx.

Thank you for your help. One more thing on my recreation list.

Per your link, I was able to create the “chrome’ folder then drop my userChrome file (from my backups) into it. Now it works!

Note: "Mark it as solved" does not seem to work but it is solved.

Thank you again.
