Thunderbird is "not responding"
Hi I am having problems with Thunderbird, i’m not sure if it’s to do with a windows 11 update or something else. Thunderbird is not responding also at the start of the ‘not responding’ emails from one of my accounts disappeared and then gradually started to reappear but didn’t get up to date and now just not responding st all. I have tried various things to resolve this, uninstalling and reinstalling Thunderbird, doing this and opening my pc in safe mode, doing this and opening Thunderbird in safe mode. Deleting and reinstalling the latest windows 11 update, reinstalling the latest Thunderbird update. I don’t know what to try next? I read somewhere to delete your profile, after saving it, and getting a new profile but no idea how to do this. Any help appreciated.

What's your OS?
opening my pc in safe mode, doing this and opening Thunderbird in safe mode.
And what happened then?
Hi OS is Microsoft Windows Thunderbird opened but curser just spinning and then Thunderbird not responding message again. No emails downloading.
What is your anti-virus software?
Try to start Windows 10 in safe mode with networking enabled.
Does the problem go away?
Windows safe mode disables anti-virus software. This is a troubleshooting step, not a solution.

I have a new protection recently installed by Microsoft, Microsoft Defender. My main protection is Malwarebytes.
I have removed Microsoft Defender and then tried starting my PC in safe mode, Thunderbird still not responding.

Windows 10 and 11 have Microsoft Defender built-in. What do you mean with "I have a new protection recently installed ..., Microsoft Defender". Which version of Windows are you running?
My main protection is Malwarebytes.
I'd rather stick with Defender, and get rid of Malwarebytes.

Can you confirm you did start Windows in safe mode with networking enabled?
The safe mode instructions are https://support.microsoft.com/en-us/help/12376/windows-10-start-your-pc-in-safe-mode
Also, in Windows safe mode, start Thunderbird in Troubleshoot Mode - https://support.mozilla.org/en-US/kb/troubleshoot-mode-thunderbird
Does problem change?
Hi Thank you for this, I hadn't been doing the correct safe mode start up. I followed your instructions and Thunderbird loaded Ok and I could access 2 of my accounts the 3rd was 'not responding' but then opened Ok. I closed it down then opened up again and all was Ok. It is now working as normal not in safe mode.
What is it that causes this problem?
What is it that causes this problem?
Most likely your anti-virus software. To avoid problems in the future create an exception in your anti-virus software (or an exclusion in case of Windows Defender) for the Thunderbird profile folder, so that the anti-virus real-time scanner will not scan it. https://support.mozilla.org/en-US/kb/profiles-where-thunderbird-stores-user-data#w_how-to-find-your-profile
I closed it down then opened up again and all was Ok. It is now working as normal not in safe mode.
Without creating an exception it's quite likely that the problem will return.
