Just finshed installing it. I installed over the top of my older version. Nothing's broke yet.

Anyway, here's the link so y'all can look over the new features.....

Haw. I found a glitch already. Maybe it's intended.

Anyway, we all know how we like to customize FF to our own liking. I have the tab bar showing at all times. I also have my about:config set to have a close tab button on the far right side of the tab bar. I don't like the close tab buttons on each tab.

Soooooo, i was surfing and i closed the only tab open and the browser closed. Closed!

Well, i found a tweak if that happens to you.

Open about:config and paste browser.tabs.closeWindowWithLastTab into the search field. Double click the entry that shows (it will be the only one) and it will turn bold and it will set to false. All set. Done.

If you use any themes, do they work in 3.5?

Most of mine worked. Those are usually the ones that the authors updated to work with the new release beforehand. And usually within a couple weeks, the others will come along with updates.

But i don't see much difference in this new release other than the Private Browsing thing they now have.

i installed it last night, had to remove most of my add-ons

Installed it earlier tonight; had to remove a couple of my add-ons (though I hadn't been using them, so no big loss). None of my themes worked, which is a shame, because I haven't been able to find a suitable theme since.

The browser itself seems pretty solid thus far, though I'm struggling with the lack of a solid theme....
