Wao !!!! So great Rated 5 out of 5 stars

It should be a standard feature of Thunderbird: allows to fill in the send to field on a single line, exactly what I was looking for!
I think it also solves this bug: https://bugzilla.mozilla.org/show_bug.cgi?id=528503
Thanks Michel!

Thanks a lot for your feedback !

Problem in Thunderbird 51 Rated 4 out of 5 stars

Thank you for your good extension;
But when I upgraded Thunderbird to version 51Beta, I couldn't send messages.
Please fix this bug.
Thanks again

Thanks for your feedback.

For bug reports, please use the email support. It'll be easier for us to communicate.
As an example, the compatibility with TB51 is fixed in internal dev version and I could ask you to test it.

Very good extension Rated 5 out of 5 stars

Odd font settings bug? Rated 3 out of 5 stars

Addon works as described.

However — and after a Thunderbird reset and some debugging work to figure out the cause — it seems this addon changes the HTML font setting in Thunderbird Options -> Composition -> General -> HTML to a size of "x-small".

Even a manual reset of the font size in a Thunderbird session is lost when Thunderbird is restarted.

Not sure if the problem is solely the fault of MRC Compose or MRC Compose in conjunction with another addon, but the bug does go away when MRC Compose is disabled.

Thank you Rated 5 out of 5 stars

I have been looking forever for this add-on. It allows me to enter 'cc' and 'bcc' fields from the keyboard (without using a mouse). Thank you!

Very useful Add-On Rated 5 out of 5 stars

Thanks for providing this excellent Add-On! It greatly improves editing recipients. Works well on OS X 10.9.5 with TB 38.2.

A great improvement to the traditional way of entering email recipients!

The latest version however breaks the BorderColors GT addon. Too many changes in the message window overlay?

[sorry for the bug report here, is there a better place?]

Thanks for your feedback !
For bug report, you can use the support email, defined in the right column.

I tested with current version of BorderColorsGT and saw no problems. (Disclaimer : I installed BorderColorsGT *after* mrc compose)
With support email, can you send me screenshots to describe what doesn't work for you ?

Perfekt – Thank you very much! Rated 5 out of 5 stars

I am impressed: You integrated my request concerning possibly deleting the grey text in the to-, cc- and bcc-lines as an option.
And you repaired the bug, I just recently told you.
I am happy!

"Send without save" not working Rated 5 out of 5 stars

Hi, version 1.8 seems to conflict with the add-on "Send without save" and the same button in the add-on "toolbar buttons". Messages that should be sent without saving a copy using these buttons are sent, but with a saved copy. Could you please check?

reply to Michel: The add-on "Send without save" does not seem to be downloadable any longer, but the same problem occurs with the "send without saving" button of the add-on "Toolbar buttons", which is available here at mozilla.org. The problem is not with saving messages or their drafts. The "send without saving" button in Toolbar buttons should send an e-mail without keeping a copy in the "sent" folder. However, if MRC compose is installed, a copy is always kept in the "sent" folder, regardless of whether you use the standard "send" button or "send without saving".

Fixed with 1.8.2, thank you!

This review is for a previous version of the add-on (1.8).  This user has 2 previous reviews of this add-on.

I can't find the addon "Send witout save" so I can't test it.
Can you describe what is the conflict ?
Mrc compose doesn't modify the "save" button. mrc compose enable/disable only the "send" button if there is at least a recipient.

Greate add, but after update to 38.0 I have a problem with this add.

I'm using PKI, but if this add is runing thunderbird not sign my e-mails and every time when I want crypt. message I have notification to configure PKI.

The problem has been identified and is being corrected. A new version will be available in next days. Thanks for your support.

Urgently needed - Thanks!! Rated 5 out of 5 stars

Thanks so much!! I just changed two week ago from apple mail to TB and I was excited about its functionality and configurability. The only thing I really was pissed off was this cranky UI for addresses of mail recipients.

I have to write many times mails to several but always different people. I always had to look up with the scrollbar who was already included as recipient. It happened twice to me, that I changed my mind during writing and forgot to remove a person, because I could not see who I have already added. With sensitive mails (e.g. in human resource issues) this could be disastrous!

Your plugin is really a relief!

Great Rated 4 out of 5 stars

Thank you for this add-on it is useful when you are sending to many addresses.

It will be perfect if:
- The email addresses are drag-and-droppable like in Outlook or Gmail. That way you can very easily move some addresses from To to Cc, etc.
- Like Outlook/Gmail, have a delete button on each email address. So you can remove some addresses very easily.

This review is for a previous version of the add-on (1.8). 


and it won't be perfect :-(
because it would be too complicated to handle addresses as objects in the existing window. I tried... and it would require to rewrite the entire compose window !

If you really want that feature, you can install addon "conversation" (https://addons.mozilla.org/fr/thunderbird/addon/gmail-conversation-view/) : the 'quick reply' mode behaves just like you want !

Copy / paste addresses from excel-Copier/coller des adresses issues d'un tableur Rated 3 out of 5 stars

hello, Bonjour

(traduction par Google)
TB31 no longer accepts copy / paste from Excel address list that ds empty box!

(But Thunderbird 24 accepts the copy / paste)
See the discussion http://forums.mozfr.org/viewtopic.php?f=4&t=122253

MRCompose either!
MRCompose sends a message to the empty addresses!.
Error message: An error occurred while sending mail The mail server responded:." 5.1.3 Bad recipient address syntax ".
Please check the recipient's address "" and try again

Would it be possible to correct this?
Would require the extension removes empty addresses before sending.

thank you

MRCompose non plus !
MRCompose envoie un message à des adresses vides !.
Message d'erreur : "Une erreur est survenue lors de l'envoi du courrier. Le serveur de courrier a répondu : "5.1.3 Bad recipient address syntax".

Vous serait-il possible de corriger cela ?
Il faudrait que l'extension supprime les adresses vides avant l'envoi.



This review is for a previous version of the add-on (1.6.2). 


As you said, it's a Thunderbird change, it has nothing to do with mrc compose.

Mrc compose only takes care of editing recipients. Then when user press "Send", it's Thunderbird that *really* sends mails.
Mrc compose helps user select recipients, but user is free to type what he wants in the textfields : so it's up to him to type correct emails adress.

Cleaning data is always a very difficult thing to implement : it depends of the state of the bogus data,
so it can't be done in a "one step" process, or a "one fits all" cleaning.
So you can *not* be sure what Thunderbird done when it was doing some cleaning! Maybe it removed some correct recipients ?
IMHO, it's much more sane that no automatic cleaning is done now : it allows you to know exactly the recipients of yours mails.

What you describe is not a mrc compose bug. It may be an idea for a future enhancement (ie add some tools to provide some cleaning of email).
For exemple, "replace line feed by comma" or "replace two commas by one". But it'll user responsability to call them.

The real answer to your problem is to provide only clean email data to Thunderbird/Mrc compose.


Comme vous l'avez dit, c'est un changement dans Thunderbird, cela n'a rien à voir avec mrc compose.

Mrc compose s'occupe seulement de l'édition des destinataires. Quand l'utilisateur clique sur "Envoyer", c'est Thunderbird qui s'occupe *vraiment* d'envoyer les mails.
Mrc compose aide l'utilisateur à choisr les destinataires, mais l'utilisateur est libre d'entrer le texte qu'il veut : alors c'est sa responsabilité d'entrer des emails corrects.

le nettoyage de données est toujours un processus complexe à implémenter : cela dépend de l'état des données
alors cela ne peut pas être fait en "une fois", ou avec une méthode "qui nettoie toutes les données".
Alors vous ne pouvez *pas* être surs de ce que Thunderbird faisait quand il nettoyait les données ! Peut être a-t-il supprimé quelques emails corrects ?
AMHA, c'est beaucoup plus sain qu'aucun nettoyage automatique ne soit fait désormais : cela vous permet de savoir exactement à qui vous envoyez vos mails.

Ce que vous décrivez n'est pas un bug de mrc compose. Cela pourrait être une idée d'amélioration future (ie ajouter des outils pour effectuer certains nettoyages sur les emails)
Par exemple "remplacer les sauts de ligne par des virgules" ou "remplacer 2 virgules par une". Mais ce sera la responsabilité de l'utilisateur de les exécuter.

La vraie réponse à votre problème est d'envoyer uniquement des données propres à Thundebird /Mrc compose.

Thank you for this Rated 5 out of 5 stars

Fantastic extension. The way Thunderbird forces one address per line is absurd. Why Thunderbird doesn't use this style of adding multiple addresses per line separated by comma is beyond me.

The only thing I didn't like about this extension is the phrase "enter one or multiple addresses..." that appears in the "TO" box in new messages. It goes away once you start typing in the box but I found the phrase an unnecessary aesthetic intrusion, as I prefer a cleaner, blank interface. So I edited the XPI file to remove the phrase. Now it is perfect.

Very well done!!

I also had the same problem as reported by ezrider with TB 31. Michel told me about the fix and after a few hours waiting, I did go to Version Information down at the page and selected to see complete version history. There I was able to download version 1.6.1. and it works again as it suppose to be, so I am very happy with the fast support! Thanks Michel!!
