Génial pour bien s'y retrouver dans ses mails quand les expéditeurs ne les renseignent pas bien. Par contre n'accepte pas les caractères accentués chez moi sous TB 7.01.
Et attention toutes les modifs sont perdues si l'on répare le dossier.

good idea, not IMAP compatible Rated 1 out of 5 stars

The idea of the add-on is good, but I can't make use of the add-on because the add-on doesn't work for mails in IMAP mail folders. In my opinion, the subject-edit-window should be expanded.

Edit: Sorry, but the description has the wrong language. I can't read French. If I put your description into the Google translator, it says to me, that I can change incoming messages with the add-on and the changes occurs at the database-message.

New Version

Hi, try new version. In this one, changes could be locals only, or server-side IMAP compatible.

Bonne add-on, même si la fenêtre d'édition du sujet est décidément trop courte (et que les modifs restent locales).

Sinon, l'idéal serait de pouvoir modifier également le contenu des messages...

Nouvelle version

Une nouvelle version 1.0.1 en attente de révision: https://addons.mozilla.org/fr/thunderbird/addon/edit-email-subject/versions/

Avec une fenêtre d'édition plus large et qui peut être agrandie

Thanks, but a much wider edit window would be even more useful Rated 4 out of 5 stars

I have been looking for an add-on that will do this and am very glad to have it. However, the editing window needs to be three or four times as long before it will be really useful to me; I need to be able to see the whole subject line to make editing easy. I tried to drag the edge of the dialog box to achieve this, but it was a set size.

New version

New Version 1.0.1 waiting for review: https://addons.mozilla.org/fr/thunderbird/addon/edit-email-subject/versions/

With wider and resizable edit window

Nice, but only local changes Rated 4 out of 5 stars

It would be nice if this tool could make changes persistent by changing the real header of the email (at least optionally)!

Otherwise, on a shared IMAP folder it doesn't really work sorting emails when the new correct names are not available to all users :-(
