1447738 - Firefox freezing when closing tabs from touchscreen

Status: RESOLVED DUPLICATE of bug 1446904

(Core :: DOM: UI Events & Focus Handling, defect)

Description

[kaha]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36 Edge/16.16299
Firefox for Android

Steps to reproduce:

Firefox frequently freezes when I close tabs in from the touchscreen (tapping the "x" button), Windows 10.

My Firefox is up-to-date (59.0.1 (64-Bit)) and my only add-on is uBlock Origin.

Actual results:

Once that happens, I cannot change tabs, click on anything or scroll in the current tab which I tried to close.


Expected results:

Tab should close when tapping the "X", however, this can be fixed by min- and maximizing Firefox (tapping the Firefox icon in the taskbar twice; the minimize button in the firefox window is unresponsive), after which the tab is properly closed.

I reproduced the issue on Nightly 61.0a1 (2018-03-25) and Firefox 59.0.1, Windows 10, Surface Pro 4.

Note: On Nightly 61.0a1, the issue can be reproduced only with the finger, not with the pen.

I am marking this issue as New.
