Firefox hangs on close

[E Guest]

Hi,

I am having a problem with Firefox failing to close when I exit the program. Although the window closes, an instance remains open in the Task manager. Each time I run and close Firefox, a new instance remains open, clogging up memory. When I try and terminate the process in Task manager, I get the message "The operation could not be completed. Access is denied." Ultimately, I have to reboot to get rid of the open instances.

I am using Firefox 25.0.1 and Noscript 2.6.8.5. Operating system is Windows 7 Home Premium sp 1 on an Intel i5 HP machine. I have Norton Internet Security ver. 21.1.0.18 installed.

I disabled all other add-ons and extensions in Firefox and the problem still occurred. When I disable Noscript, Firefox exits without hanging.

I have uninstalled Noscript and installed earlier versions back to 2.6.8.1. Problem still persists.

Any ideas on how to fix? Your help is greatly appreciated. I love Noscript and would like to keep using it.

i think this is a firefox issue, nothing to do with noscript
also reported with adblock plus here
you could try removing firefox 25 and installing firefox 24 esr or 26.0b1 (available at https://ftp.mozilla.org/pub/mozilla.org ... /releases/)
otherwise see the abp thread for suggestions

I have the same problem since updating to ff 25, and still with 25.0.1. After reading this thread:http://forums.mozillazine.org/viewtopic ... eaf0deb5c3, I saw that private browsing might be the problem for some. So I turned private browsing off, set all to clear upon closing, and in addition to that, I have to load in at least one page prior to closing FF (as on startup I have blank page.) That's resolved the problem for me.

Hi,
I have the same problem but only on Windows 7 Home. In fact, my other PC with Windows 7 Professional doesn't show the issue.
My setup: FF 25.0.1, NoScript 2.6.8.6.
Start Firefox, default home page opens, close Firefox, inspect Task Manager: Firefox process still appears in the list, memory apparently unreleased. When trying to terminate it, I get "Access denied". I also tried with "taskkill /f /pid" from the command prompt to no avail.
Tried also to start with a brand new FF profile and install NoScript as the only addon: same issue.
I'm neither using AdBlock nor Private Browsing so I can't say if these things are related.

Like I said, I don't have any such problem on Windows 7 Pro with same FF and NoScript versions.

I found a similar issue. On a Windows 8.1 PC, a freshly installed firefox 28.0 browser with the noscript plug-in 2.6.8.19 will cause:
(1) multiple firefox.exe processes (as seen in task manager) to persist after all firefox browser windows are closed; and
(2) the same stale firefox.exe processes will persist across Windows 8.1 restart.
(3) task manager's end-task button does not seem to be able to kill these stale processes.

Would appreciate any advice on this problem.

Thanks,

So if you disable NoScript, FF no longer hangs on close?

> firefox.exe processes will persist across Windows 8.1 restart

Explain.
You're actually restarting the computer or you're just putting the computer to sleep?

> task manager's end-task button does not seem to be able to kill these stale

Heh. Can't comment on Win8/8.1.

What Plugins do you have?
Are you clearing history/cache on close?

If it helps at all, I've written a small program that provides a clunky-at-best workaround for the problem. No charge.

You can download it (and the source code) here: https://firefoxkiller.codeplex.com/
