>>> My Info: Win7_64, Nightly 49, 32bit, ID 20160526082509 STR_1: 1. Open attached "testcase 1" AR: Firefox hangs and freezes all opened applications and OS itself ER: Firefox shouldn't hang, just like GoogleChrome Note: 1) This bug was filed for Firefox developers to prevent OS hang, unless they think that it's expected from e10s browser. It's not up to me to decide how you want to prevent the hang, but there's at least one option: to show "crashed tab" dialog with explanation, just like GoogleChrome does. 2) AR isn't completely accurate. If you spent 5-15 minutes near hang PC, you'll notice that sometimes mouse pointer responds to mouse movements, so in 15 minutes you'll manage to kill all Firefox related processes and get your PC back. If this is intended workflow, please tell that explicitly.
User Agent Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:54.0) Gecko/20100101 Firefox/54.0 Build ID 20170129110302 I haven't managed to reproduce the issue on the latest Firefox release (51.0.1), the latest Nightly (54.0a1) or Nightly 49.0a1 (20160526082509). When the Script is loaded in a tab the browser starts to hang, but it doesn't affect other programs and applications, I was able to switch to other applications without issue. And after 15-40 seconds, depending on the version I used, the browser becomes fully responsive again. Since the reporter's account is disabled and I cannot reproduce, I will mark the issue as Resolved-Incomplete. If anyone can still reproduce on the latest Firefox version, please feel free to reopen and provide more information.
