Start typing into a form and it creates an autocomplete popup list of things you've typed there in the past. That's nice. But your past typos show up as well. The solution? Navigate to that entry and press shift-delete. Bye bye entry.
I only discovered this by accident. Polling coworkers, most people don't know about it.
What other really useful functionality does Firefox have that nobody knows about?
Maybe obvious because it's visible in the menu (if you clicked on the tab bar): Undo closed Tab. Life safer. Ctrl-F12.
Also, when I need to reclaim memory (or restart Windows) but keep all my gazillion (well, ok, thirty) tabs in various windows, I kill Firefox and let the Session Saver restore my urls after restart.

Playing devil's advocate, maybe the OP doesn't want this to happen *every* time FF starts, just as and when he chooses.
just delete works the same.

In Firefox 2 it did require Shift-Delete. Interesting that in Firefox 3 it’s just Delete alone; thanks!
... and even in MSIE, too.
I did write about this some 2 years ago... And it had taken me a very long time to discover this, too.
