Great addon, however I experience the same thing as 'erricodavide' down below.

From this version on, when I edit a subject, the message gets appended with current date instead of its header date.
Thunderbird continues showing the correct date (the header one) and behaves accordingly, but Gmail app/webapp show the message as if it arrived at the time of subject editing process.
This discrepancy between TB and Gmail app/webapp makes your tool unusable for my purposes.

I genuinely think I'm not the only one facing this problem.
Also, updating TB to 78.8.1 doesn't solve the issue.

Any clue?

I am using TB91, so that doesn't solve it either. For now I had to uninstall the addon, but will be glad to use it, when this thing get fixed.

Hope that it will be soon!

This review is for a previous version of the add-on (5.1).
