So, ever since the first time I used Firefox, this is the only time it has ever been rendered unusable.
I upgraded my system and, when I tried to launch Firefox, all it can ever do is crash before being able to load anything at all.
I'm not sure what Firefox version it is because I only used apt-get upgrade, didn't monitor the upgrade, and was never able to check it but I think, it's 10.0.2. My system runs on Joli OS 1.2, by the way.
Anyone who can help me, please.
Right now, I am getting by with Google Chrome and I am not enjoying how I am unable to use those add-ons I've always had.
May I suggest you look again at firefox crashes for instance it includes:
You can't open Firefox because it crashes at startup even in Safe Mode:
Go to ~/.mozilla/firefox/Crash Reports/submitted.
In the resulting folder will be a text file for each crash report you have submitted. Using the View menu, arrange them by date to find out which is the newest file; and double-click on it to open it.
