I finally move .mozilla folder and started FF again
Why FF made two *.default folders?
ok, profiles.ini pointed to the right one, but...
I don't understand why 2
maybe there was some process I didn't kill?
yes that's why
hm, I still have not compatible issue
so, there is some package installed, but I've checked before... there was nothing like it
I found it!
there is an package called language-pack-hr
it hase installed files in /usr/lib/firefox-addons/extensions/
Peng: what do you use for OS?
