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

[Joshua Wise]

I can't seem to repro it now by hitting C-n while I have 9 tabs open in
one window and the download manager open.

I am currently using a Firefox that reports itself as Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.1) Gecko/20060601 Firefox/2.0.0.1 (Ubuntu-edgy).
I am using Flash 9 (not sure which minor version).
I'm not sure which Java package I have installed, but I know that I have one.
I have installed: Firesomething 1.7.0 (disabled since an upgrade), Greasemonkey 0.6.7.20070131.0, Live HTTP Headers 0.13.1, Long Titles 1.2.4, Nightly Tester Tools 1.2.1, Restart Firefox 0.3, Sage 1.3.10, SomethingAwful Last Read 1.15.1917, SwitchProxy 1.4 (disabled since an upgrade), and VideoDownloader 1.1.1.

I will post another comment with a test case if I can reproduce the bug
in the future.
