Just made the switch from Chrome to Firefox. I noticed that even on a high-end Macbook Pro, when I opened a large amount of tabs in quick succession Chrome would lag intolerably. It did so on earlier releases of Firefox but I just tried on 29 and it opened 40+ tabs with without a hick-up. Very pleased indeed

Edit: I just noticed that the text selection now works as it does in text editors with blinking cursor and all. Great feature!

The text selection thing probably means you turned on caret browsing; press F7 to turn it off again if you need to. That's been there ~forever (like, Firefox 1.0 or earlier).
