This is a great browser! I actually have been using Firefox Aurora's before this, I then went to water-fox but the newest version is slower then normal. Then I found out about Cyberfox and have to say, it's super fast, is like Firefox so I know my way around, and its undoubtedly the best x64 browser out there!.
I think it is a dumb idea to use its own profile. It was brilliant until version 28 when it still shared profile with Firefox. Nobody wants to maintain multiply profiles. And remember that a variant can never completely replace the genuine.
doesn't work with XP,but i tried,it seems Firefox has went the way of all the others new and improved just seems to be doesn't work worth a damn,i have been using Firefox since the beginning and now i am trying really hard to find something that works and doesn't stall out,chrome crashes too much,some one needs to buy the copy write for XP and continue support,
Cyberfox is great, but dude; seriously, fix your installer. It just force restarted my computer and canceled my 3 day long Render, WHILE the Cyberfox "Do you want to restart" dialog was still apparent. Happened on Windows 8 Pro x64 -- That's pretty crappy man..
