Love this add-on and use it daily. Too bad TB version 78 broke it. I hope the developer can fix it. I would pay for this add-on I use it that much. What a shame that Mozilla is doing things to their code that is breaking so many great add-ons like this one. Please try to fix this if you can. Thanks for all your work

Since Thunderbird doesn't tell you what it will disable when it upgrades, big problems ensued in upgrade to TB78. Do you plan to adjust the add-on? I would give the highest rating to this add-on but can't use it any more. I may have to see what it takes to revert. Is there another product that does the same thing?

Great Add-on for earlier versions, but it is needed on Thunderbird 78. Will there be an update? If not I'll stay with the old Thunderbird. Can't manage without this! Thank you.

I'm using this tool for years now but it doesn't work anymore since the auto-update to thunderbird 78.5.1.
Will there be an update of this tool or do you have a suggestion for an alternative?

Thanks in advance

Era un ottimo componente ma con la nuova versione di Thunderbird 78.4.0 non funziona più. Spero sia aggiornato velocemente

I have been using this regularly for years - mostly to edit the title of emails so that they can be stored and found easily. It doesn't work with current versions - I would love to see it fixed.

WORKAROUND:
1. Drag the email into a drafts folder.
2. Edit and save it
3. Drag it back to inbox. Done.

It was a great extension, but it won't be updated to work with TB 68+. As a workaround though, simply save an email as a file with an .eml extension and then open it in a text editor like Jarte. After you make the changes and save the file, drag and drop it back into TB. Works for me every time.

My four star rating is for what the extension used to be. One star lost because it the extension won't be updated anymore.

This is not working correctly. I have Thunderbird 60.8.0. I just tried this....used "Edit Source" to type a note next to text in a message. When I finished and re-opened the message, the note I typed is not there, not anywhere on the page. However, when I went to "Edit Source" again, the text I typed is still there.

Also, this says the original (unedited) message will be moved to "Trash," but I cannot find the message in any of my "Trash" or "Deleted Items" folders. (However, the supposedly edited version is in my inbox, so I didn't lose anything.)

Great addon for editing message source!

but it has severe drawback - it messes the encoding every time when a message with several different encodings is processed

It changes the subject, which I am very happy with, but the email cannot be found any more. The reason I want to use this plugin was to rename and find again.

I just saw that when I edit the source it is possible to find hen searched for. So I added two more stars...

Can, please, someone tell me if it's possible to alter the header of an email to be sent? If yes: how?
Thanks very much in advance
