Firefox 社群討論區

Hello,

Recently, (past month or so) I have had difficulty opening Firefox on my PC. Found suggestion of renaming the .exe which did work, but now it will not open AT ALL. Uninstalled, and re-installed. nothing. Renamed .exe. Nothing. It will OPEN as admin, but cannot access any settings or browse. I am at a loss, and really do not want to go back to Chrome.

Previously attempted uninstalling ESET antivirus and Defender, and still would not open.

Thank you!

I have an M1 Macbook Pro running macOS 15.5 (24F74). Often after booting up my laptop when Firefox launches it freezes. When I long press on the Firefox icon it says "Application is not responding".

I found this post: https://www.reddit.com/r/firefox/comments/1fi4p94/firefox_freezing_on_start_on_macos/ which mentions an incompatibility with Firefox and Adobe Creative Cloud. Sure enough, when I quit Creative Cloud Firefox starts successfully.

Anyone have any ideas of what's causing this?

Every time i would open the app, it would crash immediately. I uninstalled and reinstalled, had the same issue. Recently updated to Win11. Reported each time but can't get into the app so don't know what the error is.

On my pc, Mozilla Firefox continuously loops the error message, “Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window.” It then proceeds to close and loop this error. I have uninstalled and reinstalled multiple times, as well as did a “refresh” in deleting all my extensions and addons upon the new installation. Please advise. Thank you.

Still not able to get FIREFOX to open
