Yep, I'm using it now and so far I'm pleased with it, although it doesn't seem to be much more advanced than 1.5.04. Good things: it kept my bookmarks, and I can get the search bars with Google, Ebay, Amazon, etc. that I couldn't with 1.5.04. Bad things: it underlines the words I misspell like with Word or something. And I still can't keep the new tab button there between restarting Firefox. Much better than IE 7 though, considering it won't let me use tabs there.
