Steps to reproduce: 1. Launch Firefox. or 1. Cmd+T. 2. Paste "http://www.squarefree.com/start/". 3. Press Enter. Now hover over links, tabs, or items on the bookmarks toolbar. For links, the cursor fails to turn into a hand, and for the chrome items, hover effects are missing. After clicking in an empty area of the page, the problems (even for chrome) are fixed. I suspect this is a regression from the switch to Cocoa, but there weren't any nightly builds for a week leading up to the switch to it's hard to tell.
Another problem that happens at the same time: Cmd+clicking a link makes a drag indicator appear during the click, even if the cursor doesn't move at all.
I can't reproduce this.
Cannot reproduce either, verifying.
WFM here too.
