Thunderbird keeps crashing on start-up. No, it's not corrupted .msf files. I followed a link to a Thunderbird extension's homepage, which opened in a Thunderbird tab; it immediately caused Thunderbird to eat up lots of CPU and gobble more and more and more memory, until I killed it. But now when I restart it, it gets stuck before I can close the problem tab. How can I discard the remembered tabs and open Thunderbird with just the default view?

I'm running the latest Thunderbird, on Windows XP. I've looked at the profile folder but I'm not sure where the last session's tabs are recorded. (And I'm not looking for safe mode: the remembered tabs will come back as soon as I deactivate safe mode).
