DOES work with TB 3.0.4 Rated 4 out of 5 stars

I've been using Buttons! for years too; how time flies. After updating TB to 3.0.4 my Buttons! installation suddenly stopped working. A message under Add-Ons said -Does not provide secure updates-.

I re-downloaded Buttons! (wasn't the same size as my previous download with the same version number) and re-installed and suddenly the message has disappeared and it works again.

Maybe the numbering should be changed to ;-)
