Thunderbird is Slow

I found a solution: http://kb.mozillazine.org/Inbox_stays_blank

This worked just fine for me.

Had the same problem about slow downloads and even slower uploads. I disabled my Panda antivirus and it solved my problem. It worked great in the past but it reached a point where it would interrogate every letter typed. I uninstalled Panda and I installed the free AVG antivirus and it works fine. Hope this helps.

I tried to compact, its working fine

Thanks Jason!! Disabling the TB talkback feature in add-ons solved my problem. I am no longer suffering from slow startups, slow opening emails, ghost windows after sending emails, etc. Seems my problem has been TB's very own talkback feature for reporting bugs was causing the hangs.

when I opens thunerbird at first(after booting into windows)it s getting hang also displaying a message "downloading messages .......please wait"in thunder bird status bar.

When I restarts the thunderbird, it works fine.This problem happening every day. I deleted inbox.msf files, but problem is still there.

Plz tell me the soln for this

Also I have created filters.Some mails which have to go on filtered folders its coming in Inbox also(duplicating).I checked the filter settings(ie,I put 'move to ' insted of 'copy to folder'option.)
plz help me sort out this problems

thank you

There's a simple solution:
Open Thunderbird
Make a new folder
Copy all inbox msgs to the new folder
close thunderbird
Open explorer
Delete both inbox file in the appropriate folder
restart thunderbird
Copy the msgs back to the inbox
done

Hey there,

I had this problem too, and it was making me nuts since none of the convential fixes would help. No matter what I did, when I started up TBird, it would take approximately 790Mb of Memory and spike the cpu at 50% (On a 4GB RAM 2.0GHz dual core system) and then come up after 5 minutes or so.

The solution I found was somewhat simplistic. Once I found it, and took action, my performance went right back to normal. Doing a scan of my TBird directories, I found that my mimeTypes.rdf was almost exactly the same size of the memory used at startup (790Mb). I made sure that the default mimeTypes.rdf existed and deleted the humungous one. And that was that; everything was set :)

Hope this helps someone out who finds themselves in the same boat!

if your thunderbird start and then very long time thinking and after that you have for example empty inbox. this means that some mails in your inbox broken and theris only one solution in this case that i know and that is exactly perfectly work.

you need find file that correspond to your inbox and remove all string

X-Mozilla-Status: xxxx
(xxxx - number)

inside this file

this can be done for example with this script
#perl -pi -e 's/(.*)X-Mozilla-Status:(.*)/X/' Inbox

Hi and thanks alot for your help. I can recommend the solution found by Mike Golvach, cause it's the only one working on that slow starting problem. I have tried all of the posted ideas which didn't help but wasted my time, unless one. Thank you Mike for finding that solution. Clever done!

Mike Golvach's solution worked for me as well. I wonder why that file got so big?
