Thunderbird Win 7 64 bit CPU usage

I have the latest version of Thunderbird portable installed on a thumb drive and finding a some instability problems and high CPU usage. In Task Manager there two processes instances listed; one "thunderbird.exe *32" with about 50MB memory usage and continuous 13% CPU usage and one "thunderbirdportable.exe *32" with about 4.5MB memory usage and 0% CPU usage.

A check of the processes listed after exiting Thunderbird still shows they are still present and the cpu usage is the same. Restarting without using Task Manager to shut the processes down is not possible.

Thunderbird is unstable and shuts down intermittently.

Any advice will be appreciated.

Thanks

Thunderbird Itself

If you see that after you close Thunderbird, it means that Thunderbird itself did not close when you closed the window. The process thunderbirdportable.exe sticks around until thunderbird.exe closes and then does some final cleanup of files on the local PC. This can be caused by a corrupted install or by a misbehaving extension.

If you see this while Thunderbird is running, our side is normal. Thunderbird may be indexing messages, which is causing the CPU usage.

I guess it must be corrupted since the CPU usage, 13%, is continuous for hours on end, even when it is operating normal, and the performance slowed down. It became unstable after installing the last major Thunderbird update when using it on the XP Pro 32 bit system and is worse now that it is plugged into the new Win 7 64 bit system.

This is going to be a real job to delete the portable folder and figure out if the custom mail folders, custom address folders and address can be saved intact so that a lot of time will not be required to recreate everything.

Is there some way to do a new Thunderbird install into a different Thunderbird folder and copy certain files from the old folder to the proper areas in the new Thunderbird without recreating the same problem which exists now? If this is possible it might transfer all my mail, custom folders, and custom address book.

Thanks

64bit is larger

32bit apps consume more memory and CPU time on 64bit systems due to the WOW32 setup.

To do a reinstall, delete the ThunderbirdPortable\App folder and then install a new copy of Thunderbird Portable over the top. Your data is preserved.

I deleted the App folder as instructed and performed a reinstall but it still has the same problems. I think I'll just leave it alone and turn it on a couple of times a day then use task manager to shut the processes down to free up the CPU resources. I have a couple of other 32bit version programs that only use CPU time when performing operations and none when in standby. Maybe in one of the future versions it won't do this.

Thanks for trying.

Clean Profile?

If that's the case, then it's something in your profile itself. Any extensions in use? Anything else? You could try a clean install and re-setup your accounts.

Clean Profile?

The profile is corrupted and was unable to make things work. I did a new portable install and imported the address books from the old one. It is so slow with the corruption it will take forever to forward my saved Emails back through the account again. I'll just do that once in awhile as time allows. If I knew which was the Email data I could copy them directly to the new install.

Thanks

Mail folder

There is a Mail and an IMAP folder in there. Inside there you'll see a bunch of folders from your actual install. You can copy those right in.

Mail folder

This saved a lot of time.
The original Thunderbird was setup a couple of years ago with POP and when the profile became corrupted and installed the new version of Thunderbird it automatically set it up with IMAP.

Thanks for your help,
Dennis
