Rated 5 out of 5 stars

Dear @DS, your suggested edit works perfectly on v68. Thank you so much.

Oh, except that it seems to disappear from the TB toolbar each time I restart TB :(

Further investigation shows it only does not persist on the Menu Bar (which is where I always have located it). It remains ok on the Mail toolbar, though.

TB68.2.0 64 bit

This review is for a previous version of the add-on (0.7.2).
