I have similar problems. I upgraded my laptop from Dapper to Edgy and Firefox crashed every time I visit any site with flash in it. Oddly, I did a fresh install of Edgy in a VMware environment at work and I can view flash sites in Firefox just fine.
-- firefox hangs with flash plugin installed on certain sites https://launchpad.net/bugs/302 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
