Hello Every time I launch Thunderbird v78.9.0 (64-bit) I get the pop up about making Thunderbird the default. If I click on set as default and then close Thunderbird the same pop up will come up.

If I go to Tools > Options > General > System Integration > Check Now. The E-Mail is un-ticked. If I tick it and click set as default I still get the same problem.

Check the operating system for default: In Windows 7's Control Panel, go to “Default Programs”, and then “Set Default Programs”. On the left will be a list of programs installed. Click on the program you want to use as your email program - Mozilla Thunderbird, and its details are presented in the right. Click on Set this program as default to make it the default mail program.

Do you have more than one installation of Thunderbird ? I have two different installations on purpose, one has the 'Email' option selected, the other does not.

Exit Thunderbird. Check the shortcut you use to open Thunderbird. Rigth click on shortcut and select 'Properties'. The 'Target' information will tell you which location is being used for the Thunderbird you are opening.

Check in both of these locations for a 'Mozilla Thunderbird' folder and delete the 'Mozilla Thunderbird' folder which you are not using. Then empty the Recycle Bin.

  • C:\Program Files\Mozilla Thunderbird
  • C:\Program Files (x86)\Mozilla Thunderbird

You may be seeing the bug that is reported as fixed in 88b1 (first item under Fixes), and if that's the case and the other remedies don't help, the fix should appear in the next release in the 78 branch.
