Firefox keeps crashing on Ubuntu 14.04 [closed]

Solution 1:

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.

Solution 2:

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.
