I too have about a lot of tabs, 15 tabs open all the time (sure I’ll read them one day), plus a lot more of them in Panorama (40?).

Also note that when my machine hibernates and I bring it back up to life, Firefox is freezing for several minutes (I cannot use it, the tabs disappear and the address bar look weird) until it is responsive again (reacting to mouse overs, or clicks, …).

Good luck with all of that Tara, the work you are doing and sharing with us is enlightening and unusual, which makes it interesting.

I haven’t measured it, but closing Firefox can sometimes take in excess of 2 minutes. During that time, trying to start Firefox is completely impossible — ergo, my “experienced” start time blows out to over 2 minutes in those cases. And I never, ever dare minimize Firefox and leave it in the background. If I do, the only way I can make Firefox responsive again within a sensible amount of time is to kill it and restart. (Note: I regularly use about 50 tabs.)

I actually tried verifying Talos numbers with about:startup a week ago and the extension (as well as the getStartupInfo API) works great.

One side effect of the crazy optimizations is apparently that Talos’ ts_shutdown numbers are all wrong as I noticed in https://bugzilla.mozilla.org/show_bug.cgi?id=648749 (my patch there fixes the issue). Talos will try to close the browser immediately when the first page loads – but browser initialization is apparently not finished at this point, consequently you get ts_shutdown numbers that are too high.

Firefox 4 has definitely improved the second and I think it also improved the first. However stopping can sometimes still take a long time. If I do not wait for Firefox before stopping the computer, then I will get the Firefox crash startup where FIrefox offers me to select a set o ftab to open because Firefox did not close properly last time.
