Got sick of the Intel driver crashing X11, and Ubuntu releasing their upgraded packages only on the recent version (Horny Heron or something). Bit the bullet, did the upgrade, and...
...Firefox 3beta got installed! What the hell?!? Poof go all (well, most) of my extensions, you know those handy things I use for, oh, locking down Firefox, anonymous browsing, other small conveniences that make using such a poorly-performing browser worthwhile.
Included in these was Zotero, in which I have quite a number of documents stored for offline viewing, and which *still* has no independent UI for accessing them (even the Open Office plugin requires a running instance of Firefox). Suckfest à la mode, just what I ordered!
A search of the Zotero forums, though, turns up a link to the Nightly Tester Tools plugin, which can be used to run an extension for a previous version of Firefox. Zotero is now up and running on Firefox 3beta.
Version 3 does seem to be a bit faster than 2, and hasn't been too crashy. The theme/extension writers should really get their act together and update/port their stuff before this puppy hits the street.
