hello mohamed, there was a update released just recently that should address some crashes on facebook. please go to firefox > help > about firefox and make sure that you've already updated to version 18.0.1...

Hi, my firefox version is showing at 18.0.2

It is updated, any further suggestions?

Hello, I have the same problem, my Firefox version is 19.0 and still crashing.

Update:

Not sure if this is the problem here but:

There is apparently a known issue that is being worked on by Facebook developers.

From (sumo)meeting notes https://etherpad.mozilla.org/sumo-2013-03-11

 Firefox Desktop

 Facebook crashes - Caused by the Facebook Desktop plugin. The developer has pushed an update. Users should all be on the newest version in the next few days

There could be a bug filed on this, but I did not find it.

Meanwhile other posts indicate that the workaround is to disable the Facebook Desktop plugin.

I have this same problem my latest crash ID is bp-c4e2eb48-39b6-47f8-81c1-7ce822130612

tried everything suggested.

thank you

hello snaumovski, it looks like a avg-related library is playing a part in this crash. please go to firefox > addons manager, disable all avg extensions & plugins and see if this can address the issue...

I note some of the related bugs are fixed in Firefox 23. A workaround may be to try Firefox Aurora which is already Firefox 23, although I am not sure AVG would be compatible with Fx23 yet.
