Rated 5 out of 5 stars

I would love to give this add-on a good review, but I can't get it to work properly with Thunderbird 140.7.0esr. I have set the option to use BCC rather than the To line, but when I click to create a new message, none of the addresses are imported. Placing the cursor in the BCC box and clicking to add selected addresses at the top of the compose window also does nothing. If I change the settings to use the To line, it seems to work as described. I can use work-arounds (selecting all To addresses and moving them to BCC) that way, so the add-on is at least partly functional, but it would be cool to see the BCC option work out of the box. Thanks for your work on this one, it'll be a help ... with a few adjustments.

Replying to Helge: I didn't find any clues in the Debug function, but then did a full reboot of the laptop (Acer running Win 11), and when it came back up, the BCC option worked. Changing the rating to five stars!

I just updated and tested it on 140.7.0esr, it works for me with the BCC enabled (my default too). On what system are you running it? You could go to tools -> Addon and Themes -> select Extensions on the left -> click the cogwheel button (settings) -> Debug Addons -> click the Inspect button on RepSel -> check if there are errors in the console tab or the like. Thanks for reporting!
