Best addon ever! This functionality was sorely missed!

Great & one small request Rated 5 out of 5 stars

This is a great Add-on. Thank you!
Could you add the option to make disappear the words "enter one or multiple emails separated by commas"?
I know it und for me these words are too much (aesthetic)...
Thank you

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.

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!
See bugzilla https://bugzilla.mozilla.org/show_bug.cgi?id=1124124
(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.

Excellent !!!

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!!

problem with TB 31 Rated 5 out of 5 stars

MRC Compose is great, but there seems to be a compatibility issue with TB 31. I cannot send e-mails with MRC Compose 1.6 and TB 31.

This review is for a previous version of the add-on (1.6).  This user has a previous review of this add-on.

Thanks for your feedback. Version 1.6.1 is already uploaded and is waiting for Mozilla final validation. It should be available in few hours.

Rated 5 out of 5 stars

I've been looking for a long time for an add-on like this. Should be included by default in Thunderbird. Most other e-mail clients allow sending to several addresses by using a list of comma separated values. Now Thunderbird does it too, with the help of MRC Compose!
Works flawlessly. Many thanks to the developer.

random crash when query LDAP

I'll look at that report.
Please use the support email for such feedback : it'll be much easier for me to ask you some complements. Thanks.

I really appriciate for all of your effort. It works well on my windows system with the latest TB, version 24. However, autocomplete feature does not work with LDAP. Besides, I'm not able to find the option related LDAP from "MRC Compose Option" page.

My software is icedove 17.0.10 on Debian 7.

Does this addon support LDAP on Linux?

Thanks for your feedback !
In order to answer your question, can you send me en email (use support email indicated in the right column) ?

Rated 5 out of 5 stars

Great add-on. Just what I needed.
It works without any problem with TB24. To remember the settings for CC and BCC, just check the corresponding choices in the "fields appearance" tab in the MRC Compose Options in the Add-ons manager. It is true that changing these options in the compose window is not working even with TB24.1.0.

This review is for a previous version of the add-on (1.6). 

Glad you like it !
Changing options in the compose window is only temporary, just for the current window. The only way to have the options permanent is through the settings panel. It's not a bug, it's a feature ;-)

does not remember Show CC and Show BCC settings Rated 1 out of 5 stars

Was 5 Star. Before TB 23 or TB24 working OK.
But now: It does not remember Show CC and Show BCC settings when creating a new mail. When I select Show BCC it does not show the BCC emailaddress I set in the TB account settings. Now 1 star

This review is for a previous version of the add-on (1.6). 

Which version of TB are you using ?
MRC Compose has been tested on TB24, not on TB25 or more as they are pre-releases.

Exactly what is needed but for a buglet Rated 3 out of 5 stars

Just what is needed and thanks for it :)

But ... the usual drop-down list of matching addresses as the address is typed does not appear.

With the error console open, as soon as a single letter is typed into the To field:

Timestamp: 03/11/13 11:14:33
Error: NS_ERROR_XPC_CANT_MODIFY_PROP_ON_WN: Cannot modify properties of a WrappedNative
Source File: chrome://mrc_compose/content/mrc_compose.js
Line: 1719

Same behaviour with all other add-ons disabled

Thunderbird 17.09
OS: Slackware64 14.0

Sorry for posting a bug report in a review but I could not find out how else to do it.

This review is for a previous version of the add-on (1.6). 

Andreas Wagner (who developed the LDAP part) confirmed that the problem is related to LDAP and TB17 (it's ok with TB24). He's working on modifications. Cheers.

Great, but problems with 1.5 and TB24 Rated 4 out of 5 stars

This add-on is great, but alas it stopped working with TB 24:The "Send" button doesn't get enabled when I enter addresses in the To or CC field. This used to work in older versions.

I disabled all other plugins except MRC compose: problem persists.
I disabled MRC compose plugin: problem vanishes.

There's one workaround: write email, save to Drafts folder, open mail again from the Drafts folder, send. (The send button is enabled when you open a draft). However, this is too much work.

This review is for a previous version of the add-on (1.5). 

Thanks for your feedback !
The "Send" button problem is identified and will be corrected in version 1.6. It will be available in few days.

probleme avec la v1.5 et TB24 Rated 4 out of 5 stars


J'ai le même souci que "ezrider", à savoir qu'avec MRC Compose activé, je n'ai pas accès au bouton "Envoyer" lors que j'écris ou que je transfère un email. Ce bouton est grisé;

Par contre lorsque je désactive ce plugin, dont je ne peux plus me passer (!) je retrouve bien le bouton "Envoyer".

Pour compléter et comme demandé :
* OS : windows 7 ultimate 32 et 64 bits (sur 2 pc différents bien sur).
* Addons : au total j'ai 52 addons activés dont pas facile de faire la liste, mais avant de trouver le truc avec MRC Compose, j'en avais désactivé 17 qui concerne de près ou de loin la fenêtre de composition de message.

* Test 1 : je viens de désactiver tous les addons sauf MRC COmpose et le problème reste le même.

* Console d'erreur : aucune erreur, aucun message ou avertissement ne concernant MRC Compose.

* Test 2 : Toujours avec tous les addons désactivés, je viens de remettre la version 1.1 de MRC Compose et le problème est toujours là.

* Idée : N'étant pas expert, je soumets néanmoins le fait que Mozilla a du changer quelques bouts de code dans cette fonction "Envoyer" qui entre en conflit avec votre code ....

Pas facile de trouver le "truc" avec ceci, mais j'espère que vous pourrez solutionner la chose.

Désolé d'avoir été si long !!
Bon courage et merci pour cet addon

Ultimate Addon Rated 5 out of 5 stars

Hi ,This is a great plugin which should be default feature in Thunderbird. I have been using this plugin for more than three months but suddenly from september 15 autocomplete of mail id feature is not working. I am using the Ubuntu Thunderbird 13.0.1 is it possible to fix this issue.

This review is for a previous version of the add-on (1.5). 

Thanks for your feedback.
Can you perform some checks ?
- what is your OS ?
- what is the version of mrc compose ?
- open the "Error console" from the "Tools" menu, then create a new message and try to enter a recipient. Then if there is new lines in the error console, just send them.

Great add-on!! Rated 5 out of 5 stars

This is a great add-on, that corrects one of Thunderbird's most evident flaws in the "Compose" window. I've wished for a long time for something like this (which should have been Thunderbird's default, actually) and now I can finally manage recipients for my messages in a much more efficient way. I would have rated this add-on with five stars if it weren't for a small bug that I've just come across. Hopefully, it can be corrected by the developer. The symptom is this: every time I try to send a message, for some reason Thunderbird complains that "There is no TO recipient, only CC/BCC". This is obviously not the case, as I can see that there is indeed a TO recipient. And if I ignore the warning and "send it anyway", the message is sent without issues. I don't know what is triggering this warning. I'm running Thunderbird 17.0.8 (locale es-AR) on Windows XP (Windows also in Spanish). By the way, the warning text is displayed in English, which is neither my Thunderbird's nor my Windows' language, so I'm guessing the warning is caused by this (or maybe another?) add-on

(UPDATED with bug symptoms and system information)

BTW, I just tested the bug described in the comment below mine (the bug with the attachments) and I can't reproduce it. I'm not seeing the attachment being incorrectly added to message #2



Eureka! I've found the cause of the bug that I was experiencing. This add-on is found "Not guilty" and therefore its rating increased to some well-deserved 5 stars :)
The "guilty" add-on is Flexible Identity (https://addons.mozilla.org/en-US/thunderbird/addon/flexible-identity/). It has an option that displays a warning "if there is no TO (only CC/BCC) recipients". Unfortunately, it seems that these two add-ons (MRC Compose and Flexible Identity) are mutually incompatible. Flexible Identity simply doesn't work when MRC Compose is being used :(
I hope this incompatibility can be fixed, because I'd hate having to choose between one or the other.

This review is for a previous version of the add-on (1.5). 

Thanks for your feedback !
I understand how annoying is what you describe, but I just tested your test case and had no problem replying.
Can you list other addons installed in your Thunderbird ?

And thanks for testing attachments too !
