[Bug 66350] Re: Firefox uses high CPU for extended periods of time when spawning a new window with many tabs already open

[Adrian Saldanha]

Confirmed here, also.  Firefox uses 100% of one core of a dual core CPU
when opening a new window, when I have many tabs open.  This is always
the behavior, no matter what I use.

My extensions:
Adblock, Add N Edit Cookies, Adsense Notifier, Canadian English Dictionary, Download Statusbar, DownThemAll, FasterFox, Firebug, FireFTP, FoxClocks, Greasemonkey, MediaPlayerConnectivity, mplayerplug-in, Add Tab Button on Tab Bar, RefControl, Restart Firefox, SearchStatus, SwitchProxy Tool, Tamper Data, VideoDownloader

Usually have quite a few tabs.  As I said, it always happens, but I
haven't tried any debugging.
