Status: VERIFIED DUPLICATE of bug 429903

Firefox nightly builds (2008041606 and 2008041707) often hang on page load, e.g. pretty consistently when navigating on http://www.istartedsomething.com/ to the full post "Pictures of new and updated Surface Demo apps", as of now the 3rd post:
http://www.istartedsomething.com/20080418/pictures-of-new-and-updated-surface-demo-apps/#more-2878

As recommended in bug 418811, I attached windbg, and recorded a stack trace using "!analyze -v -hang" (not "hung" as mentioned in bug 418811).

The stack trace ends at js3250!JS_GetPrototype, so it seems to be different to bug 418811. I'll attach the log.

Reproducible: Always

Attachment: another log, 20080418 nightly, fresh profile with adblock plus

On another machine I ran the same tests with a fresh profile, and the 2008041807 nightly.

The stack trace is similar, but not identical a bit further down...
The hang only occurred after I installed Adblock Plus.

Eh, I should have duped to this, but everything is over in the other bug now.
