Firefox crashes repeatedly

[satimis]

Hi all,

Ubuntu 12.04 64bit

For unknown reason today Firefox crashes repeatedly when I first start the computer

Having tried following steps without results

- delete all old firefox data
- run safe mode
$ firefox -safe-mode
- reinstall fireforx
$ sudo apt-get install --reinstall firefox

Pls help. I'm now posting on an Ubuntu12.04 VM(guest) of VirtualBox on this PC

TIA

B.R.

Well if you disabled all addons during safe run and still crashing. I would delete the ~/.mozilla folder and start fresh. The /.mozilla folder is not removed on a reinstall. It remains.

Edit: If me. I would log out and log back in and restart firefox after deleteing ~/.mozilla folder. It will create a new one when you restart Firefox.

Hi,

Thanks for your advice,

During crashing there was an autoreport automatically sent to the development team of Firefox. Later there was an automatic feedback suggesting deleting all virtualbox guest addition files on /opt. The feedback only popup once and I couldn't trace it anymore.

However when I looked at all /opt directories;

$ sudo find / -name opt

/etc/opt
/opt
/var/opt

They were empty directoires

Hello

The folder that you need to remove to get a clean start with Firefox is .mozilla rather than .mozzila (with two l's rather than two z's). In addition, be sure Firefox is NOT open anywhere on the system when you remove the .mozilla folder.

Sorry, it was my typing mistake.

Tried again.
$ sudo rm -r /home/satimis/.mozilla

Reboot PC

$ sudo find / -name .mozilla
No printout

$ firefox
Firefox starts after a while it closed/crashed

In addition, be sure Firefox is NOT open anywhere on the system when you remove the .mozilla folder.

What you meant "anywhere"?

Firefox is NOT started on the host

What you meant "anywhere"?

On a different destktop (in case you use multiple desktops).

If you've not installed any addons, and firefox is still crashing after a fresh install and a newly generated .mozilla folder, I'd try downgrading to a previous version of firefox and repeat the process to see if the crashes continue or stop. If they stop with the older version, file a bug report on the crashing version with the firefox devs.

Just thought of something else you can try...

I've read a couple of times in the past where someone simply changing their Firefox font made it stop crashing.

It might not help, but would be an easy fix if it does.

I see, thanks. It is not my case.

If they stop with the older version, file a bug report on the crashing version with the firefox devs.

I don't think it is the problem of Firefox. It has been running here (the host of this PC running VirtualBox) for couple weeks without problem. The same version Firefox is also running on 4 VMs (guest-OS Ubuntu 12.04 desktop).

IIRC what I have done recently was installing MSWindows8 on a VM(guest). It was a nightmare. Sometimes it boots and another time it fails to boot. Still Firefox was running without problem. After running update and upgrade on host, Firefox starts to crash.

I booted previous version kernel of Ubuntu 12.04 but Firefox still crashed.

I have tried locating the message from from Firefox development teams without result. Any advice in this respect to find it on this PC.

I'm prepared installing Google Chrome instead but I will try it on another HD of this PC first. Not on this HD because this is a vitualization PC with many VMs running. In case of problem there will be lot of work to recover/reinstall them.

Deleting MSWindows8 VM(guest) including all files doesn't solve the problem. Firefox continues crashing.
