Firefox crashes

Posted

Firefox always crashes when trying to open it. If I select restart Firefox, it crashes again. I have to select Quit Firefox to break that cycle. After quiting Firefox, I am forced to always start up in Safe Mode. If I don't, I can not open the browser. I've uninstalled and reinstalled multiple times and this does not resolve the issue. I've tried to refresh Firefox, that does nothing to resolve the issue.

Start Firefox in Safe Mode {web Link} by holding down the <Shift>
(Mac Options)
key, and then starting Firefox. Is the problem still there?

While still in Safe Mode,

In the address bar, type about:crashes<enter>. Note: If any reports do not have BP in front of the numbers/letters, click it and select Submit.

The crash report is several pages of data. We need the report numbers to see the whole report.

Using your mouse, mark the most resent 7 - 10 crash reports, and copy them. Now go to the reply box below and paste them in.

Some of your crash reports weren’t sent to the Mozilla Servers.

In the address bar, type about:crashes<enter>. Note: If any reports do not have BP in front of the numbers/letters, click it and select Submit.
