Do you know if this Issue happens with the Adobe (or other's) PDF Plugins too by Chance?
Version: unspecified → 4.0 Branch
I don't know. I'm not using PDF plugin because it's always been a bit unstable for me and the full Adobe window is more usable. I can't find an embedded PDF right now to test it. I don't know of any other plug-ins, I guess I don't have any installed.
Oh wait, it also happens exactly the same with Microsoft Silverlight. If that helps.

I just ran into this exact problem. I didn't realize that I had right clicked flash and was wondering why the tab was not closing. Going back to test again, I noticed that all mouse events were not happening (CSS, JS, mouseover, hover, etc) until either left or right mouse button had been pressed. Middle click blocked everywhere so links, bookmarks, close tab didn't work. Same problem in Flash 10.2 and Foxit Reader 10.0.1. Current testing in early 5.0b1 in win7 and winxp. Mozilla/5.0 (Windows NT 6.1; WOW64; rv:5.0b1) Gecko/20100101 Firefox/5.0 I also believe the platform should be x86 not x86_64 since there is no 64bit builds in windows at this time.
Has somebody found something useful by now? It still keeps bugging me badly. Watch a YouTube/Vimeo video, then close the tab middle-clicking on it. Fails every time.
