Firefox Support Forum

So I installed the Window Titler add on. First the Firefox main general toolbar menu didn't work, which was fixed by closing down every window and Firefox and re-launching.

Now though when I use Yahoo in Firefox, I can't reply, forward or select ANY of the buttons to action an email. Other buttons work. But if I launch Yahoo in Safari they work.

Problem happened exactly as I installed the add-on. Any ideas what's going on?

Hello, it is possible to change this orrible black firefox icon on Dock? it is orrible... a black hole.... There is possibility to change with clear icon? thank you

- Marquis has colonised my search page. - I used to be able to get rid of it temporarily by going into troubleshoot mode and going through that whole process twice - oddly, it never worked first time. - Now that doesn't work. - I can only get to my DuckDuckGo homepage via my bookmarks, which means I can't have more than one page open at a time. Firefox opens by default in Marquis. - I downloaded paid-for antivirus software with no results, so I'm reluctant to get anything else unless I'm sure it will work. - I notice that several people on this thread and elsewhere have reported this intrusion. - Does anyone know what to do about it??

I can't get Firefox to store bookmarks on my Mac since I installed Monterey 12.0.1. I managed to find some instructions on your trouble shooting page but they do NOT work. Hate to give you guys up, but unless y'all can help me fix this, I'll be moving on.
