I'm running Firefox 9.0.1+build1-0ubuntu0.11.04.1 (that's on Linux Mint).

One of the tabs has a site loaded which crashes Firefox each time it loads.

Therefore, I can't close the tab quickly enough after starting Firefox to stop that site loading.

How can I make Firefox "forget" its current session?

You can also start Firefox in Safe Mode by quitting Firefox and then going to your Terminal and running:
firefox -safe-mode

Source: How to start Firefox in Safe Mode

A bit late but I confirm it's normal behavior, safe mode only loads the strict minimum from your profile in order to prevent cases like these.

From safe mode, can I get Firefox to forget the tabs open in "normal" mode? – eoinoc Jan 10 '12 at 11:24
Tools/Options/General/StartUp and set "When Firefox starts" to "Show a blank page" – stuartd Jan 10 '12 at 11:51
Fixed by just entering safe mode: When I started safe mode, it gave me the screen "Well that's embarrassing". I was able to choose "Start new session". Firefox in normal mode now starts with my normal homepage only, which was the setting already... – eoinoc Jan 10 '12 at 12:17
