408787 - Being able to kill a thread for an open tab thats causing firefox to hang

Status: RESOLVED DUPLICATE of bug 407117

(Firefox :: Tabbed Browser, enhancement)

Description

[Joseph Ssenyange]

User-Agent:       Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0; SLCC1; .NET CLR 2.0.50727; .NET CLR 3.0.04506)
Build Identifier: 2.0.0.9

It would be cool to be able to kill a thread/tab that causing the whole firefox process not to respond(hang). A situation where you have a number of open tabs and one makes firefox stop responding, you kill the entire firefox process but with hope of restoring to the previous session when restarting the firefox process. However every time you restart the process the tab still makes browser not respond. Its quite annoying to start a new session and have to go through you entire history  to open over 27 tabs.
It would be cool if you could be able to kill a specific tab thread for example from another mozilla session though it would raise again other security concerns.

Reproducible: Always

Steps to Reproduce:
1. Open a tab having a script or a big pdf that will take time to display
2. Kill process
3. Restart firefox and restore session
Actual Results:  
Keeps reopening the tab hence hanging again

Expected Results:  
I should have an option of selection specific tabs/websites that i want restored where restoring session.

A Tab does not run in a single Thread, also a window does not run in it`s own Thread.

But you describe to different things in your bug report, your summary means that firefox should be able to kill a hanging Tab/thread which is imposssible and your expected results are about session restore (btw: The component "Session restore" would be correct instead of your selected "Tabbed Browser") 

marking as dupe of bug 407117
