I was watching some Adobe Acrobat videos over the internet when suddenly IE8 crashed and the tabbed window just closed. Immediately after, a yellow speech bubble (or tooltip box) pops up, pointing at that tab with the following text (roughly).

This tab has been recovered (yes we are the hero)
A problem with the web page CAUSED Internet Explorer to crash!”

Then I switched over to FireFox. The same error happened, but at least FF3 is more modest.

We’re Sorry (don’t worry, it’s ok, foxy)
Firefox had a problem and crashed (not blaming the web page, Adobe, at all). We’ll try to restore your tabs and windows when it restarts.
To help us diagnose and fix the problem, you can send us a crash report.”

So at least FireFox is going to fix the problem for us. Nice work.
