660698 - firefox freeze dialog is too slow to appear and unfriendly

Status: RESOLVED INCOMPLETE

(Firefox :: General, defect)

Description

[Notlost]

User-Agent:       Mozilla/5.0 (Windows NT 6.1; WOW64; rv:6.0a2) Gecko/20110530 Firefox/6.0a2
Build Identifier: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:6.0a2) Gecko/20110530 Firefox/6.0a2

when firefox freezes, from plugin-container OR as javascript becomes unresponsive, firefox freezes totally for a long time before the box appears

Reproducible: Always

Steps to Reproduce:
1. Go to a website where javascript freezes the browser.
2. Wait the REALLY long time for the box to appear.
3. Stop the script


Actual Results:  
The freeze goes on long enough that the average user in my house will just kill the program instead of waiting. 

Expected Results:  
The box to appear BEFORE windows decides ff is no longer responding.

You could probably put the UI is a separate thread fro JS, but that might not be easy. A quick fix is to set the 'freeze' timer to a shorter value.

if it's the unresponsive script warning, you can lower the timeout with these instructions :

Note that many people think the default (10 seconds) is too low ...

I think the default, from a user standpoint, is NOT 10 seconds, however  it is occurring. I had to switch to IE to do my browsing for at least ten minutes before the dialog appeared. and on the test site it didn't appear until the script had finished.

Also, the ENTIRE firefox process freezes, not just the current window.

Tested with latest update, the problem still exists. I waited 10 minutes before killing the app with task manager. I had set the wait time to 4. The box did not appear.

Can you attach a screen video capture of the issue. It's still unclear how to reproduce it. Thanks.

Dammit. The video is 149 mb.
Should I upload it to rapid share, or what?

Try converting it into ogv file format at a low resolution. It should solve the problem.

Are you still able to observe the issue you have logged?

Comment 15

[Notlost]

Yes. Still  occurs.

I'll upload it to youtube.
IT seems to be working.
