I'm still hitting this a lot (several times a day) on Nightly (64).
I'm using 63b3 and crashing with while using Waze map editor.
Should this be solved in 63b3 ? Or my crash is about other bug ?
We have a separate bug for this crash: Bug 1488427
Fernando, do you have a STR or the crash is random?
Flags: needinfo?(matafagafo)
It's a STR, very easy to reproduce.
* go to
* Login
* right click on the map and start to drag the map around, in some seconds the crash happens. 

Do you want I post this on Bug 1488427 ?
Flags: needinfo?(matafagafo)
Thanks a lot for this STR. I wrote a patch.
