This works great for my use: changing the subject line to something useable. Please get it to work for 78.5.

This is a "must have" add-on to change the subject of all those anonymous invoices and those fools who use an old subject for a new email. I was avoiding TB 78 but it has crept in - need this updating to work ASAP. Pretty please!

This is really a great tool, I love it. Please upgrade to Thunderbird 78.X

Dillinger, amazing work on one of the best Add-ons.
Temporarily dropping 1 star as it does not yet work on TB 78.4 (which I love, a huge improvement IMHO over older TBs)
Hopefully a new version comes out soon.

I am writing this in reply to elliottqk's comments on September 15. If you are only interested in editing the subject line of messages, you can try the addon EditEmailSubject, which is recently updated to work with TB78.

I have been using this since February. I still love it. Can't do without it and now of course TB is updating to v78. Will you be updating this as well or must I stick with v68 for now? Thank you for considering.

I'm not updating TB past v68 until this is available

Nice addon to change a few things ...
But could you please add to your addon the ability to check the real date and real time an email you received was really sent to you and was "really" received on TB ?

Love this add-on. I organize my emails by changing the subject line. For a while this add-on did not work. Thank you to the developer for fixing it. Very simple use and works well.

Eccezionale. Per un periodo non era più disponibile e per me si tratta di un componente aggiuntivo indispensabile. Consente di modificare l'oggetto delle mail ricevute, la data, l'ora e altro. L'utilità consiste nel poter ordinare a piacimento le mail, ad esempio i modelli creati che si vuole avere in una determinata sequenza. Cambiando l'oggetto si può identificare subito una mail con parole chiave.

Grazie per aver ripristinato questo componente, spero che sarà sempre disponibile anche per future versioni di Thunderbird. Se possibile farò una donazione allo sviluppatore.

It is really nice to have this ability to change the Subject line on emails. Thank you for restoring it.

This was really one of the most useful addons that existed. Many thanks for upgrading to T68.
It really is incredibly useful for correcting inaccurate headers or deleting Re: x 10....
Or adding in relevant information to the Header as required.
Well done again!

Many many thanks for the update!
I often change the email subjets, to better search the email.

At the first of the year, I decided that I needed HeaderTools badly enough that I would backlevel Tbird to the last release in which it worked. Last week, I vowed that it would be the first thing I did this week. I had just finished backing up my system and downloading the installer for TB60.9 when I little bird :-) whispered in my ear, "Check for a new version of HeaderTools one last time before you do anything drastic."
Bless You, Dillinger!
This utility belongs in the small cadre of such stupendously useful "free" software that I am willing to support it financially. How may I do that?
And WHY isn't it an integral part of Tbird?

Thank you, there is a "Contribute" button on the Add-on page but I haven't activated it (yet). I'll look into that, probably need a PayPal account or something like that.

So glad to have found this add-on. The previous "EditEmailSubject" with the shortcut 'e' was great. When TB updated and I lost functionality of subjects I was crushed.... Now I can again with this. Great job Dillinger. I was looking through your work all very nice.
If you 'have nothing else to do' :-) can you do a something like the add-on "ColumnsWizard" - we lost that one with the TB update as well and Mitz doesn't seem to be active anywhere nowadays.
Thanks, JR

I also "revived" Edit Email Subject, you can install that too, if you want.
I'll have a look at ColumnsWizard.

Edit:
Apparently Micz added Christopher as dev for ColumnsWizard, but he may be too busy these days.
We'll see, it is not a very simple add-on so it will take some time.

Pls add shortcut for editing subject (older version had "e" key).

This review is for a previous version of the add-on (2.1). 

The shortcut "e" comes with the Edit Email Subject add-on.
Adding it here would conflict with Edit Email Subject.
In the options for this add-on you can choose a shortcut key yourself.
