1495020 - Window hangs with Unresponsive script chrome://global/content/bindings/text.xml:29

Status: NEW

(Toolkit :: UI Widgets, defect, P4)

Description

[13hu]

Attachment: Console hang after clicking Debug unresponsive script

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:62.0) Gecko/20100101 Firefox/62.0
Build ID: 20180913170346

Steps to reproduce:

Unity desktop Ubuntu 16.04

Multiple tabs and windows open (1 regular window, 2 separate incognito windows all with at least 2 tabs), streaming music in one regular tab

In a Private Browsing session window with 3 tabs, trying to close active tab. None of the websites seem JavaScript heavy.


Actual results:

Hang, unresponsive script warning

A script on this page may be busy, or it may have stopped responding. You can stop the script now, open the script in the debugger, or let the script continue.

Script: chrome://global/content/bindings/text.xml:29

I clicked debug, but the Console window isn't rendering (see screenshot).

I also can't switch tabs or click anything in that window (no button previews even).

Extensions uBlock Origin, HTTPS Everywhere, Disconnect

Same issue line is mentioned at https://openclassrooms.com/forum/sujet/angular-probleme-a-charger-un-json/90942524

Sorry I don't have further debug info.


Expected results:

Tab closes normally

Entire window doesn't hang
Console doesn't hang after clicking Debug unresponsive script

Can you reproduce this? Does it happen with extensions disabled?

The bug has a release status flag that shows some version of Firefox is affected, thus it will be considered confirmed.
