You could try ConfirmBeforeDelete by klades (aka Kaosmos). Look for it or klades on Mozillazine forums for more details.

I've used this super little shield for years but now, sadly [quote="drakoshaa"]Is there anyone who is willing to adopt the extension and update it for TB 3?[/quote]

I like this addon. Do you plan on making it compatible with TB 3.1?

Usefull, but should work on folders too.

Very useful to delete stuff bypassing the trash can. However that behavior has to be configured in the options of the add-on.

great extension, i just have a habit of shift deleting everything and this saves big time.

This add-on enables you to delete emails more effectively, highlighting several at once as well as not opening emails automatically after deleting the one above it. Very useful!

This review is for a previous version of the add-on (0.2.5).
