Firefox 4 - Memory Useage

[suarve]

Hi,

I'm on Win 7 x64 and am using FF4.

Is the following normal?

I have roughly 20 tabs open. When FF4 loads the memory useage immediately levels out around 470 MB.

I've just been doing a bit of light browsing and have a quick look at the memory useage after one hour - it was a huge 2.2 GB.

Is this normal, as I don't rember FF3 using that much.

Thanks

Well, may have found the offending plugin. I was currently sitting at just under 2GB with all my original tabs open.

I randomly noticed in the bottom right hand corner that firebug was running for all pages. Turnied this off and after about 5 mins the memory useage shot own to around 500MB.

If you right click on the small firebug icon you get the latter option.
