Firefox 3.5b99 is now available from download.opensuse.org/factory or
download.opensuse.org/repositories/mozilla:/beta
I have it installed in both 11.1 and Milestone 2. Looks good.
Using it now on 11.2 Milestone2 updated from factory Oss repo. I agree it looks good, been using it over 2 days. However I have no sound with Flash streaming internet video (BBC iPlayer). Sound works to amarok, but as you know my KMix crashes on start.
