Since yesterday, every time I visit Youtube Firefox crashes. Also, it crashes on some other video streaming sites (or pages that include a video player like jwplayer for example), but not every time.

I have started Firefox in save mode, and also reinstalled it. I also uninstalled flash player - still crashing (Note that I use Youtube's HTML5-player as standard).

I can't find any solution on the internet. Maybe somebody has some ideas to fix Firefox? I can't even guess what could be the reason for those crashes.

  • I'm posting this as a comment since it might be argued that it isn't exactly an answer. Lately, my experiences with BOTH FF and GC have been sooo bad that I have them both loaded and use them both concurrently so that I'm slightly less annoyed when one freezes or drops out. I don't blame ubuntu. I'm not sure what's causing this. Oh and last week I actually opened Opera at one point. – gyropyge Jan 20 '15 at 13:25
  • @gyropyge Yes, it's really strange. I don't blame Ubuntu either, in fact I don't know who to blame (Mozille maybe?). Anyway, I will use Chrome for pages that don't work in FF currently, and hope it will be fixed soon or someone has a solution. – exception1 Jan 20 '15 at 13:51
  • actually I think I may know what this is. I've noticed that seemingly every time there's a big hack, such as the recent sony thing, or the discovery of a BASH bug, everything goes crazy for a few weeks as sysadmins try to fix everything. My guess is that the fault lies neither in FF or GC but rather that all the sites are suddenly slightly incompatible with the expectations of the web browsers. – gyropyge Jan 20 '15 at 13:57
  • Well, that's a valid point. However, for me only Firefox doesn't work. My brother, using same Ubuntu and Firefox versions, doesn't have this problem (like no one else, except me). I think it should be something more specific. – exception1 Jan 20 '15 at 14:01
  • I hate to have to say this, but given the limited information, I'll assume that your real problem stems from using 14.04 – gyropyge Jan 20 '15 at 14:18

If somebody is interested in the solution, here it is:

I don't know why but some parts of streamer seemed to be missing on my system. I am sure that neither Ubuntu nor Firefox were updated right before the crashes began, so I can't tell the actual reason why the bug occured.

However, solution was quite simple:

sudo apt-get install gstreamer1.0-*

Downloads and installs a bunch of gstreamer libraries, now everything works fine again.

you need to reinstall Microsoft true type core fonts and adobe flash player both.first remove ttf-mscorefonts installer as

sudo apt-get remove ttf-mscorefonts-installer

then reinstall 

sudo apt-get install ttf-mscorefonts-installer

and accept Microsoft's license using tab key then reinstall adobe flash player

sudo apt-get install flashplugin-installer

then firefox will not crash.

  • When reinstalling on 14.04. I ran into the following error message: File "/usr/lib/python2.7/socket.py", line 571, in create_connection raise err IOError: [Errno socket error] timed out Processing triggers for fontconfig (2.11.0-0ubuntu4.2) ...
