is there any reason to use that? I mean pretty much all users would have to upgrade their browsers
I'm watching the demo video in Firefox Minefield right now and it works like a charme. Video without flash means for me (on linux) no random crashes or lockups. And if someone is too lazy to upgrade their browser then well, there are a bazillon flash video sites out there for them, no?
And what os are you running that a reboot was required for firefox?
OS is vista, but the reboot was required by firefox, not the OS.
