Hm, I don't see ANY differences between Firefox 4 and Firefox 5. o.O It looks just the same!
I have noted a couple of differences.
For one, it seems to be a little faster than 4. Not much to the point where it's that noticeable, though.
The other, I'm not sure if it's new, but you can do a little something called "pin app" now. To learn more about it, go to the following link.
http://support.mozilla.com/en-US/kb/what-are-app-tabsI've been trying this new feature with a few sites I visit often, and while it has it's ups and downs, depending on the site, I'm actually liking this new feature a lot. There are some sites that I wouldn't recommend using it on, (one being deviantART) but for the most part, it's really nice.
So yeah, not much of a difference, but there is at least one big one.
