Comment 16 for bug 441552

I have this problem too (as I have reported it as bug 438575 ... but it seems to be a duplication of this one) on karmic running on x86 32 bit, I have three machines having this problem, so not only a single case. Firefox always report that I should restart it, but then it reports that again. Also sometimes (after firefox and/or xulrunner upgrade with apt-get maybe?) my already working extensions disappearing and the only solution to get them back is disable all extensions, cancel upgrades, restart then enable all of them, then restart firefox again ... Sure, I have no extension upgrade since a while now, since it does not work.
