The general theme is hangs, both finite & infinite, and the ability to provide additional details to enable investigation of the issue. Bug 1278794 is an example issue that can not be investigated further. Possible solutions here is a specific about:hangs page or options on about:performance that provides exportable hang history.
Could we track this as part of profiler work?
Yes, can you create a meta bug to collect this? I believe there are others as well.
