HTTPS Everywhere 1.0 causing crashes on multiple sites
Please refer to this bug:
I can confirm that this extension causes easily reproducible crashes in http://www.interviewstreet.com/. This doesn't happen with version 0.9.7, but it happens with 1.0 and 1.0.1 This is in Aurora (future Firefox 8).
It could be Mac OS-only, nobody has confirmed in any other OS.
