264006 - Clicking away from a newly opened window/dialog causes browser to freeze

Status: RESOLVED WORKSFORME

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

Description

[Timofey Vorobyov]

User-Agent:       Mozilla/5.0 (OS/2; U; Warp 4.5; en-US; rv:1.7) Gecko/20040617
Build Identifier: Mozilla/5.0 (OS/2; U; Warp 4.5; en-US; rv:1.7) Gecko/20040617

When a popup appears that asks the user to confirm opening a secure connection,
clicking into another open window causes browser to freeze, eating 99% CPU. Same
behavior occurs when I open DOM inspector by accident (wrong keystroke), than
click into a window that was previously active without waiting for DOM inspector
to render the current page.

Reproducible: Sometimes
Steps to Reproduce:
Either:
1. go to the url shown above, switch to english
2. click "Citibank online login"
3. When a new window appears, click back to the previously active window

or:

1. while rendering a page, type "DOM Inspector" hotkey
2. click on the browser window



Actual Results:  
In both cases:
Observe a freeze - browser controls are ineffective, dragged windows do not
redraw. The only solution is to kill the browser.


Expected Results:  
No freeze.

Tried your scenarios a few times, nothing special happened. No freeze occured.
You could try updating to 1.7.3 (although I doubt that will change anything), or
try with a fresh profile. Do you have any extensions installed (TabBrowser
Extensions, PrefBar etc.)?

Timofey, have you tried with a fresh profile? Can you still reproduce this?
Otherwise, please resolve with solution WORKSFORME.
