Hi, The Gecko Profiler used to be notoriously unstable on 64-bit Windows. (If you're curious: it's mostly because the unwinding rules for Win64 require the system libraries to do a lot of synchronization, which our stack walker would often call in ways that could deadlock.)
Ever since the last Quantum Flow work week, I've been working on fixing these issues. As of this week's nightlies, all of the hangs that have been reported to me are resolved fixed. There might be some rare corner cases still remaining, but I'm confident that the most frequent problems have been addressed. So my ask is: if you've previously been deterred from using the profiler on Win64 builds, please give it another try! Flag me on any issues you find and/or mark them blocking bug 1366030. I will treat these bugs with high priority since I want to keep Quantum activities unblocked.
