TB 115 has a lot to like - so much that I immediately added another contribution. Then I noticed that there was no HTML tab in the composition window, so no chance to fix broken HTML (from copied source). I'm pretty sure that facility was not native, but came from the ThunderHTMLedit add-on -- but there seem to be ''NO'' add-ons. So I came looking for "115 add-ons", and the first hit is the [[https://support.mozilla.org/en-US/kb/thunderbird-115-supernova-faq | TB 115 FAQ]] -- but it says nothing about add-ons! IAC, a search for ThunderHTMLedit returns nothing, so that great add-on may be gone anyway, but what is happening with TB 115 and add-ons generally (and why does "115 add-ons" get a hit on the FAQ when the FAQ is silent on add-ons)? [As much as I like TB 115, this may send me back to 102.]
