Firefox 26 error
Fixed by installing language pack
So, really quick: Firefox 26 is out and I installed it via apt-get on Kubuntu.
On upgrading from Firefox 25.0.1 I couldn’t start Firefox and got an error in a small window:
XML Parsing Error: undefined entity
Line Number 239, Column 5: <broadcaster id="devtoolsMenuBroadcaster_DevAppMgr"
Turns out that there was some change to the language packs and the installed language packs (en-gb and en-sa[?]) failed to load as they weren’t listed as compatible.
Easy fix for Firefox
Simple fix was to:
sudo apt-get install firefox-locale-en
After that it starts and performs as expected.
Thunderbird 24.2.0 too?
I also did an equivalent for thunderbird:
sudo apt-get install thunderbird-locale-en
Don’t know if that was required but it seemed sensible. Certainly Thunderbird 24.2.0 runs without any problems now.
Still got an error?
There is still an apparent error in the console:
(process:9163): GLib-CRITICAL **: g_slice_set_config: assertion `sys_page_size == 0' failed
But this doesn’t affect Firefox whilst running.
Did that fix it?
Hope that helps – if so please comment to aid others searching for a fix. Thank you.
