Description

4 years ago
This bug was filed from the Socorro interface and is 
report bp-8691948f-9b87-425f-929d-a75fc2141031.
=============================================================

Ran into this after:
1. With Facebook open (although I don't think this matters), opened Tools/Options.
2. Tab to list of categories and select Security.
3. Tab to Saved Passwords and hit Space.
4. Enter a search string because I want to look up a password I had saved.
5. Tab to Show Passwords, and Yes the dialog that pops up.
6. Look up the saved password.
7. Press Ctrl+W to close tab.
8. landed back on categories list in Options, press Ctrl+W again to close tab.
9. Crash.

It's even simpler than the above:

1. Tools/Options.
2. Tab to list of categories, focus is on "General.
3. Ctrl+W. Boom!

Then this could point to bug 1076816.

Note that I have to have keyboard focus in the list of categories on one of the items. If I tab into the settings themselves, like onto any of the checkboxes of the General page, for example, and then hit Ctrl+W, I don't get a crash.
