Firefox supportforum

Recently a popup notification came up when I opened firefox on my mac. Its been awhile since I opened it and without thinking I clicked : o ~ Now I worry if it'ss ledgit? Does Firefox give a popup box in top right corner when it needs an update? I wasn't on any strange website or anything but I'm always concerned and dont remember seeing that before.

My firefox now says its up to date after it restarted ~ it's running 125.0.3

Any advise is appreciated.

I just migrated to iMac 2019 27" with Venture OS from imac with Yosamanite. Firefox looked weird with TINY tabs and search window, Too much space. I've tried updating and restarting Mac but no change. Same with themes. You can see the screen with open Firefox.
