I forgot to close Firefox before rebooting my system, and now Firefox gives me this dialog whenever I try to open it:

We're sorry

Firefox had a problem and crashed

I'm running Ubuntu MATE off a 64 GB microSD card in a Raspberry Pi 3B with 1 GB RAM, 1.2 GHz quad-core processor, and an integrated WiFi chip. The OS and all packages are up-to-date. I've tried running it from the command line as a normal user, with sudo, and as root. I ran apt-get install firefox --reinstall, and that had no effect. I've also tried both answers to this question How can I fix this?

  • How much RAM do you have? Did you tried firefox --safe-mode? – N0rbert Mar 3 at 16:49
  • @N0rbert 1 GB, it's a Pi 3B – Zenon Mar 3 at 16:50

    The crash is logged in your Firefox profile (in your home folder), so reinstalling the package won't affect things. – dsstorefile1 Mar 3 at 16:54
  • @dsstorefile From what I can tell, that should be in the /,mozilla/ folder, which isn't there. Running ls ~/home/zenon/.mozilla/ returns an error that there is no such file or directory. – Zenon Mar 3 at 16:55

    Thank you! I thought ~ just meant the filesystem. /.cache/ shows a hzad34mx.default and /.mozilla/firefox shows things including profiles.ini – Zenon Mar 3 at 16:59
