Details

(Whiteboard: [Snappy:p1])

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.

I don't exactly know what it means but I guess it's a good idea :)
