No, I do not seem to be able to reproduce the crashes I experienced.

I extracted the FF 10 to my personal directory, ran it, and -- although it seems to use my old profile (bookmarks and addons are there as usual, addons except zotero deactivated, of course) I encountered none of the former difficulties: Several items of differant kind saved from different sites -- no crash.

What's next, shpould I do any more (different) testing?

Gitty K: That crash report appears to be from the same build you were using before. That's definitely not from the official Mozilla English Linux build, which has a different Build ID.

Gitty K: To be clear, if you're at the command line within the extracted directory, you should run './firefox'. If you're in the GUI, just double-click on 'firefox'.

msellhoff: OK, that's promising. Best-case scenario this is just a problem in the Ubuntu build. I'd recommend continuing to use the Mozilla build, and let us know if you run into any crashes with that.

I'll do that, continue with the Mozilla build, do some research. Maybe try to activate some of the other addons, hm? I will post any news.

ok, can't figure out what I did wrong the first time, just downloaded the English built and saved about 20 items without crash so far. double checked the about window and it doesn't say anything about Ubuntu. All my add-ons are activated, by the way.
(edit: "re-"tried it with the German Mozilla build and it works fine as well)

You're right, Dan, all addons enabled, no problems with the Mozilla build, although I saved a lot of different items from different sources now. No crashes.

I have the same problem. I was using the FF plugin as a connector, running standalone. I'm running FF 10.0 on Linux Mint 10

After the latest restart of Firefox, I cannot start the standalone, and I get the message "zotero is running but not responding".

My crashes have happened while saving items by clicking the icon, the latest one on Google Books http://books.google.com/books?id=8oeXQAAACAAJ&dq=ranabir+samaddar+political+subject&hl=en&sa=X&ei=Fw8yT761KqXlsQKX_cnhBg&ved=0CDcQ6AEwAQ
and the previous ones on various journal websites, sage and taylor & francis

The mozilla urls of the the last 3 crashes are

Incidentally, on opening an amazon link http://www.amazon.com/Emergence-Political-Subject-Ranabir-Samaddar/dp/8132102908/ref=sr_1_1?ie=UTF8&qid=1328681854&sr=8-1 the zotero icon is missing and the page has the loading arrow endlessly circling. Though this is possibly due to the non-responsive zotero process

Thanks for finding a solution.
Could you please post the exact url of the firefox build that has to be
installed by ubuntu users?
Also, I think this problem has to be mentioned in the zotero download page. Note that most new users will just conclude that "zotero does not work" without even looking at this discussion.

sorry Dan, i just saw your message, my build is from the official firefox stable ppa. I'll try getting it from their website, if that's got something different

Works me too now. Thanks a lot!

it updated this morning and I just tried it, but it still crashes

The one we are supposed to use is this right?

Thanks,
Rick

You need the official Mozilla version of Firefox until this is fixed.

or you can upgrade to the most recent version of Ubuntu - i.e. 11.10 - which isn't affected.

ajnaram: What matters is the build you're running, not the version. If you're running a Ubuntu build, you need to install the official Mozilla build or upgrade your system.

wsetyonugroho: Nothing to do with the .firefox directory—that's data, not program files. You just need to run the downloaded Firefox version until Ubuntu rolls out a fixed version. Or just upgrade to a newer version of Ubuntu, where this doesn't occur.
