Status: RESOLVED WORKSFORME

(Firefox for Metro Graveyard :: Browser, defect)

I'm seeing this a bit too often lately. The browser gets stuck after several operations. I can access Windows' menus: charm bar, or can change Firefox settings (show tabs), but can't close/open new tabs or type in page or URL bar.

This is probably always related to closing and opening tabs.

I can reliably reproduce with the following steps: 
1. Activate "Always show tabs" from Settings.
2. Open five-six tabs using the + button.
3. Close each tab using the x button.
4. Repeat steps 2,3 while clicking faster through tabs if it can't be reproduced at first

Actual result: can't close/open new tabs or type in page or URL bar. restart needed to resume.

Can't find a good story to block against, so filing separately.

I think this could have been caused by the same issue as Bug 856244. If you double click the add new tab button fast enough, you can end up with your clicks trapped.

Taking a stab at the story this should be attached to

I can no longer reproduce this with the latest build - haven't had any such problems while testing yesterday. Not sure what fixed this, so resolving as WFM. Probably bug 856244 should have been fixed as well.
