Are Extensions Crashing Your Safari?

Safari 5 has been pretty solid for me. I run with 10-20 extensions active at all times and test many new ones every day. So you'd think that if there was crashing to be had, I'd be getting it.

I do see crashes sometimes when I'm installing or uninstalling extensions, but that's pretty much it, like Chris here...

The good folks on Twitter seem to be having a tough time, however, some are zeroing in on the Adblock and Javascript Blacklist extensions.

Let's get to the bottom of this. If you're getting crashes, is it with certain extensions? Are extensions even involved?

Please weigh in and help solve the mysteries.
