guylifshitz / DontRestoreTabsRevival

This is a remake of the DontRestoreTabs extension. It is compatible with Thunderbird 68+. The code is based on the tabControl extension.

Build and install

To run this code, simply ZIP the file and change the filename and extension to "dontRestoreTabsRevival.xpi". Then install on Thunderbird with "Install add-on from file".

Testing

To test, open some e-mails and close/exit Thunderbird. Then re-open Thunderbird and all the tabs you had open previously open should be closed.
