I have done all this:
On order to use the add-on, turn off HTML composition (per account setting, Composition & Addressing → Composition → Compose messages in HTML format) and also make sure that "mailnews.send_plaintext_flowed" is disabled in the configuration (about:config). Furthermore, mailnews.wraplength needs to be non-zero

I get the little Line Wrap selection in the top right and it toggles off and on but I don't get any line wrapping.

I have two email accounts and both are set for HTML turned off for composition. mailnews is set to 72 and flowed false.

I have tried it on two different machines. One on TB 102.7.2 the other on TB 102.8.0

What else do I need to do?
