You likely did not lose anything, because, by default - the extension doesn't actually delete any messages: It only moves them to the trash. Please look in your trash folder, and you'll likely find all those messages.

To actually delete anything, you have to explicitly change a setting on the review dialog to perform a permanent deletion, then provide a second authorization when I warn you about deletion being permanent.
