It was working yesterday before me going wild with installs and uninstalls (at least I got back audio working 
)
Anyway - firefox won’t start anymore, in terminal it gives:
“Couldn’t load XPCOM.”
Googled it and ended up trying to run xulrunner, which ended up with this error:
“/usr/lib64/xulrunner-1.9.0.5/xulrunner-bin: symbol lookup error: /usr/local/lib/libgconf-2.so.4: undefined symbol: ORBit_TypeCode_epv”
any ideas what to do ?
Reinstall Firefox.
Dont worry, you wont lose bookmarks, history, cookies, extensions and settings.
I tried doing so from yast, nothing changed :((
maybe I should delete left over folders too (I don’t mind losing all my settings - system is quite fresh so I didn’t add any bookmarks that I wouldn’t remember)
In this case also delete your /home/<username>/.mozilla/firefox directory.
Instead of reinstalling firefox try to force-upgrade your xul rpms.
