I was using Firefox for some time this morning when Firefox has suddenly shown "not responding".

Now, he opens with "not responding". I can open it in safe mode but nothing works. The button "restore" & "start new session" does not work. It does not connect to any web site. I had a lot of tabs open when it crashed. There is no crash report (latest is 6 weeks ago).

If this does not work in mode without failure, then disable all extensions and then try to find out who is the cause by allowing both the problem reappears.

  • Choose "Disable all add-ons" on issues to troubleshoot Firefox in Safe Mode to set window to disable all extensions.
  • Close and restart Firefox after each change through "file > exit ' (Mac: ' Firefox > leave";) Linux: "file > exit ')

Create a new profile as a test to see if your profile is the source of the problems.

See "basic troubleshooting: a new profile:

There may be extensions and plugins installed by default in a new profile, so check that in "tools > Modules > Extensions & Plugins" in case there are still problems.

If this new profile works then you can transfer files from the old profile to the new profile, but make sure not to copy corrupted files.
