Firefox Support Forum

Tēnā koutou (Hello everyone),

I deleted Firefox to re-install it after playing with profiles and that not working how I wanted it to (yet). I uninstalled the app from the applications and the library on my Mac and reinstalled Firefox. Now when I open Firefox it says that it's up and running but no windows actually open up for me. I have uninstalled and reinstalled it again and it still won't open windows. I have to force quit Firefox as nothing shows up in my top tool bar to even show Firefox as open.

How can I get Firefox to actually install and be functioning on my computer again?

Running (as of an hour ago) macOS 14.5 (was using previous up to date OS when I installed Firefox again.

TIA

Hi there. I wiped my C Drive and reinstalled windows 11 on my PC. Completely from scratch.

The first few thing I did is download firefox. I believe in the first boot of firefox, I can download things fine, I installed Ublock Origin add-on and a few installers for the app that I need to use. I can't recall when, but after a few reboot, I noticed that Firefox can't download anything, every download link I click on, the download fail instantly, I can't install add-ons as well.

I tried reinstall firefox, changing download folder target, nothing helped.

Can you take a look please? Thank you!
