Key notes
Thunderbird is one of the best desktop email clients on Windows 10 thanks to its ease of use and efficiency. However, users have been complaining that Thunderbird is not responding on their PCs for some reason.
This can be annoying, as it renders the email client completely useless. Fortunately, it is not the most challenging issue, as it only requires a tweak or two.
Why does my Thunderbird keep freezing?
How can I fix Thunderbird if it’s not responding?
Below are some of the troubleshooting steps you should try before applying any of the fixes in this guide:
1. Run Thunderbird from Safe Mode
If Thunderbird is not responding, it might be because of some apps or processes. Restarting your PC in Safe Mode will only enable the needed drivers and services to run your device.
If Thunderbird works in Safe Mode, then the problem is most likely caused by a third-party app.
2. Disable antivirus
In some cases, Thunderbird might not be responding because your antivirus is blocking it. The quick fix to this is to disable your antivirus temporarily.
The steps above only show how to disable Windows Defender. If you have any third-party antiviruses, you should disable them too.
3. Uninstall third-party antivirus
If disabling your antivirus does not fix the Thunderbird not responding issue, you might need to remove the software altogether. This is especially the case for AVG, as users have confirmed that it does not work well with Thunderbird.
That is all there is to fix the Thunderbird not working with Gmail, not responding, and other variations of the issue. All you need to do now is follow the instructions carefully, and things should return to normal.
