[Bug 1135745] [NEW] Clicking on firefox button causes unity freeze

Thu Feb 28 13:31:47 UTC 2013

Public bug reported:

On a fresh boot, clicking on the Firefox link on the sidebar in Unity
causes Ubuntu to freeze completely. No response to anything other than
ctrl-alt-shift-prntscr-b R-E-I-S-U all show no response. Tested in Gnome
shell where it works fine. Using Ubuntu Tweak to clear cache has
occasionally relieved the issue and starting from terminal with -safe-
mode sometimes works, following which Firefox will launch as normal.
Returned to Unity after using Firefox in Gnome-shell and freezes again.
Running 13.04 up to date as of 1pm GMT 28/2/2013.

I had this problem in 12.04 for some time, installing the AMD website
FGLRX driver seemed to relieve that issue but I cannot install the AMD
driver successfully in 13.04 as the dkms module will not build. What I
don't understand is why Firefox should be the only application to
exhibit this behaviour.

Things to note:
Have set Firefox cache to 0
Machine is running behind transparent proxy (Squid on 12.04 server).
Have checked file system several times.
Have not noticed any SATA issues logged relating to this drive.
