I do love that JavaScript and Flash killer thing-ies they've got, but I have to "teach" it which sites are okay and which aren't. Plus the Adblocker is very much improved over its older incarnation and now comes paired with a nifty list of ads to block (download separately) that gets continuously updated. I'm shockingly add-free at the moment. Hell, I don't even get ads or drop-down boxes on Megaupload or YouSendIt any more. *floves*
Also, vast improvements in DL ability. Firefox always used to crash on me if I tried to DL too much or too fast. I'd say the 1.5 build is massively, massively more stable than the 1.1 I had.
But best. tool. evah?
gSpace. No kidding. It's an upload interface that literally turns your Gmail account into file storage. I've been playing with it all morning sending MP3 files through it and...let's just say it's a hell of a lot faster and smoother than just emailing the damn file. Plus, it gets around that pesky 10 MB limit that GMail has on attachments.
Damn, I am impressed with this thing.
Another good addition, it's now a hell of a lot easier to remove extensions. Now you can do it with a click of the button, so, thank heavens for that.
Overall, now that I'm used to the new Firefox and extensions, I'm duly impressed.
