Thunderbird takes over 1 hour to start up

Hello

When I restart my PC (windows 10) and open Thunderbird it takes over an hour to start up. I get the 'Thunderbird is not responding error' all the time and it is very very slow. Even when it eventually starts up, it crashes every time I click on the screen for about a day before it gets back to normal. I have just been leaving Thunderbird open but I need to restart my PC every now and then.

I have no Antivirus apart from Windows Security and have added the entire contents of the Thundebird file within the :C drive (Local Disk) to the exclusions.

When I start my windows PC in safe mode with networking, Thunderbird starts up immediately and I have no issues, but I have no idea what is causing it to be so slow when in normal start up and how I can fix this issue?

I have been having these issues for a long time now and have tried everything I can think of.

Any help would be greatly appreciated, have used Thunderbird for years and it would like to stick with the platform!

Many Thanks,

Hello

what are you calling the 'Thunderbird file' ? is it under c: \program files ? if yes, it's the profile (usually under c:\users\your-login-name) that should be added to the exclusions.

Hello,

Thanks for the quick reply.

Please see attached screen shot showing the folder I have added.

There are no files in the login name folder referencing to thunderbird.

Thanks!

Yes, your exclusion is not useful. You should have a directory called C:\Users\(userlogin)\AppData\Roaming\Thunderbird

In W10 Settings, type startup in the search box, and post the Startup Apps that are enabled. These apps are bypassed in Windows safe mode, so one of them might account for the slow TB start.
