User Agent: Mozilla/5.0 (Windows NT 6.2; WOW64; rv:13.0) Gecko/20100101 Firefox/13.0.1 Build ID: 20120614114901 Steps to reproduce: Using Firefox on Windows 8. Switching between tabs, closing tab(s), new tab, etc. Between 4 and 12 tabs. Actual results: Response to the command by Firefox (closing the tab, switching to next tab, etc. ..) is super-slow. One second at least, can be more. Expected results: Instant execution of the action... Seems that the issue mainly happens when the Win8 task manager shows 70% or more of OS RAM as used (<= 30%). BUT the slownessis not (directly, at least) related to the OS lack of memory: All the other applications are not slow AT ALL and I have to other browsers with between 4 and 30 tabs where I can do anything (create new tabs, close, etc. ... ) without any slow down. Maybe Firefox is swapping too often when free OS memory is under < 30%? Maybe Firefox uses memory a way Win8 does like...? I'd by happy to provide more detailed info, just tell me how.
Lets use this as a tracking bug for janky tab strip performance.
Depends on: australis-tabs-win
