1241462 - hung tab notification should indicate which tab is hung

Status: REOPENED

(Firefox :: Tabbed Browser, enhancement, P2)

Description

[u123541]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:46.0) Gecko/20100101 Firefox/46.0
Build ID: 20160112030227

Steps to reproduce:

In order to stress Nightly, I have 14 FF windows with a total of over 500 pages open (526 counted two days ago). Usually, this runs fine; but lately it's been quite slow (understatement).


Actual results:

Now seeing processHang (A web page is slowing down your browser. What would you like to do?) messages appear & disappear on their own with no clue as to the offending page(s).


Expected results:

A clue as to which page would be greatly appreciated -- unless button_stop is a placebo; the page's URL should be available. A "Switch to tab" would be better.

This is a process per tab related bug. currently a single hung tab means all tabs are hung.

I also regularly get the message "A web page is slowing down your browser. What would you like to do?" but the options are useless without knowing which tab it is.  If it's the tab or page I'm waiting on and wanting to interact with next, I'll choose Wait.  If it's another tab I'm not using right now, I'd choose Stop It.  The information about *which* web page it is is essential information for determining the answer to the question.  This is an important UX issue!
