While writing a comment on the blog-site mentioned above I minimized mozilla to chat with a friend over ICQ. 
When I made FireFox visible again its window did not react and it consumed 99% CPU.

I made a stack-trace, maybe full stacktraces can be generated using talkback-debug-information:

your stack trace isn't valid because you don't have symbols, in the future please don't paste such stack traces (rebuild --enable-debugger-info-modules or --enable-debug if you want usable stack traces).

1.) well if mozilla.org would deploy builds with debug-information in it I would post the stack-traces with debug-information.

2.) Furthermore talkback is able to recontruct symbols just from the adresses, so why isn't this possible here?

3.) #0  0xb7e50800 in nsCycleCollector_forget ()
but wthe adresses are resolved to method names right? To be honest I don't understand the problem.

I tracked the problem down to this site: http://blogs.sun.com/fatcatair/entry/tiered_compilation_issues

It does not always happen (for me it happend "just" 3 times, but always when I was there).

I'll try to get a debug-build working and send more useful information.
