Every time I log into Yahoo Mail Classic.. I can read my mail, but when I go to send a mail I cannot access my contacts with "TO" or "Insert". Then when I go to log out from my mail, and close Firefox, it keeps running in the background and I have to start my task manager and close it with the "End Process" button. I am not having this problem when I use Internet Explorer... Firefox seems to hang on other pages, and having to go into task manage to "End Process" on  a regular basis... Seems like a Java problem, but I am not sure. I reinstalled Firefox, updated to latest Java, Adobe Reader & Flash no avail.

Reproducible: Always

Steps to Reproduce:
1. Start FireFox
2.Goto Yahoo mail ...Log In and try to create new mail in the old classic version of yahoo mail. Try to insert a contact in your new mail using the "TO" or "Insert Address" button... System hangs...  Log out close and shut down Firefox...
3. Go to Task manager , open process tab..and Firefox is still running.

Expected Results:  
Firefox should close itself down every time it is closed.

Is this a security problem???????? I don't have the experience to say, but it makes me nervous about why this is happening. I am checking the security button below, because I don't know.
Rick: Can you try running in Safe mode without any extensions to see if the problem persists? explains how to do that.

When I run it in safe mode it is working ok. Re-tried it after safe mode, and got the same crash from yahoo mail.
One of your addons seems to cause your problems.
Please go to tools/addons/extensions and disable the addons one by one and restart Firefox between your tries. You should find the broken extension with that way.

Turned all off and found it was the Zone Alarm Browser Security 
Safe browsing toolbar. The versions inside the tool bar is :
Zone Alarm Browser Security
Spyware Scanner
Anti-Phishing Database
Spyware Sites Database 04.130

Now my concern is it something that is attacking while in Yahoo mail that Zone Alarm Is shutting down, or is it a bug with mozilla and/or zonealarm?

Found that it is not just in yahoo mail that the zone alarm browser security plug in hangs firefox browser, but it happens at several other websites. I am not sure that I am able to run a stacktrace with WinDbg, might be beyond my technical skill. But I will give it a try. It might take me a day or two.

(sorry for the delay)
1. you installed the 64bit version of windbg, please go back and install (And use) the 32bit version of windbg
2. since you aren't running as an admin, you need to use a path you can write to,


.logopen /t "${HOMEPATH}\firefox-debug.log"

Please use "add an attachment" to attach the file (it should be in your %userprofile% directory

Closing old bugs in the Plugins component. We aren't going to track issues in 3rd-party plugins in the Mozilla bug tracker. In addition, support for NPAPI plugins will be removed at the end of this year; for more details see the post at

If there is a serious bug in Firefox, it needs to be filed in the "Core" product, "Plug-Ins" component.
