User Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:50.0) Gecko/20100101 Firefox/50.0 Build ID: 20161208153507 Steps to reproduce: 1. load test case 2. open Javascript debugger 3. set breakpoint in resize handler (e.g. on console.log() call) 4. resize window Actual results: Mouse pointer is stuck in resize mode. Nothing can be clicked (not in debugger, not in Firefox, not in any other program). System is unusable until you kill the Firefox process.

It can be reproduced in Fx50.0.2 & 51.0b7. The mouse pointer is stuck in resize mode, but Firefox and the system is normal, press F8 key can to rescue from this situation. The works fine with e10s on in Nightly, but can be reproduced while File menu - new non-e10s window, whether devtools.debugger.new-debugger-frontend pref.

So you basically can not debug such an event handler, right?

I can't seem to reproduce this on any Firefox (all with e10s enabled) on the Mac.
