User Agent: Mozilla/5.0 (Windows NT 5.1; rv:10.0a1) Gecko/20111005 Firefox/10.0a1 Build ID: 20111005130150 Steps to reproduce: 1. Open up a window without tabs-on-top with say 3 tabs 2. focus the middle tab 3. Hold left mouse button down on from bottom of the tab(below text) and move a straight line down() below the tab bar(about 5 pixels into the webpage) 4. Release and go straight up (I know this is a little hard but if you're using a touch pad this is a lot easier) Actual results: The tab thinks I am still dragging it even though I have released my mouse(I made sure I did) Expected results: The tab should stop dragging. I tried this on Nightly 10.0a Windows XP SP3 Home
I can reproduce this in Beta 8.0 on OS X 10.7 Lion. Bug 675340 is relevant. There seem to be at least two different ways of triggering this phantom drag.
