The full release in now available. If you get it today you’ll contribute to Mozilla’s World Record attempt if that sort of thing appeals to you.
I have installed it and apart from some plugins not being available all is well. A bug I’ve had since 2.x is still apparent which I was hoping would be fixed – an issue with my bookmarks toolbar which extends off the side of the screen. The bug is that the little double drop down arrow (the one that reveals the bookmarks that wouldn’t fit in the bar) still isn’t visible until I have clicked one of my bookmarks. It’s probably because my Stumble bar shares the line. Oh well the awesomeness of the awesome bar makes up for that!
