Public bug reported: Firefox sometimes freezes and turns gray when the process "JS GC Helper" is active. This is not a temporary freeze, but blocks Firefox completely until you close it.
There are two ways you could force quit Firefox: 1. By killing "firefox" in the system monitor, "JS GC Helper" won't be killed, and upon restart Firefox will tell that another instance is running (because its lock file hasn't yet released). 2. By killing "JS GC Helper", firefox closes also and you can restart it.
