Status: VERIFIED FIXED

(Core :: XPCOM, defect)

Description

[Simona Badau, Desktop QA]

This bug was filed from the Socorro interface and is 
report bp-58717263-5617-404c-b362-13b952161014.
=============================================================
After updating to the latest Nightly (Build ID :20161014030204), it crashes every time you write something in the address bar.

Steps to reproduce:
1. Launch the latest Nightly
2. Focus the address bar
3. Start typing an URL

Expected results:
Navigating should be allowed.

Actual results:
Firefox crashes the second you type anything in address bar.

Regression range: I'm currently searching for a regression window and I'll post the results ASAP.
  
Note:
Only the x86 builds are crashing on Windows 10 x64 bit. The 86_x64 builds are not crashing.

Looks like the following bug has the changes which introduced the regression:

Nightly build is pre-alpha build dedicated for testers.
If you can't handle it, just use stable or ESR build for everyday usage like other people.

The signature [@ ns_if_addref<T> ] seems like another regression from this bug, or another variant. I'll just put it in here for now.
Examples:
  bp-e8ed76aa-c741-4b56-940b-a7d0c2161014
  bp-c5c04ece-cded-405e-97e0-118372161014

This has been fixed by backing out bug 1308317, the new Nightly works properly.
