When Firefox freezes and reboot is needed, Firefox always tries to open the same tabs that caused failure before.

I use tabbed browsing all the time. When I open a tab to a website that causes a problem, freezing Firefox (but not the computer) I usually find that I can clear the Firefox problem only by rebooting the computer. I am then dismayed to find that Firefox then tries to recreate the same set of tabs that caused the problem in the first place, causing Firefox to freeze a second time. Usually I can get out of this by closing Firefox and waiting a very long time for Firefox to fully close so that it can be restarted again.

This problem happens in version 4.0 as well as in the last version of 3 that I had. I recall that in some earlier versions Firefox would ask if you want to recreate your tabs or open as a new browser window. I always took second option. That choice is no longer appearing.

Chosen solution

Set the pref browser.sessionstore.max_resumed_crashes to 0 on the about:config page to get the about:sessionrestore page immediately with the first restart after a crash has occurred or the Task Manager was used to close Firefox.

That will allow you to deselect the tab(s) that you do not want to reopen, but will allow to reopen other tabs.
See:


To open the about:config page, type about:config in the location (address) bar and press the "Enter" key, just like you type the url of a website to open a website.
If you see a warning then you can confirm that you want to access that page.
You can use the Filter bar at to top of the about:config page to locate a pref more easily.
