Five Stars: Works as described. I use GMail, and I contributed my $2.99, if you use this Add-On, so should you.

Encrypted Communications Darren Chaker Rated 5 out of 5 stars

Darren Chaker loves this tool to encrypt communications with popular social media apps. It's great to securely communicate with others, and keep contents private from those online who want to know your details. Try it out, I did!

Rated 1 out of 5 stars

Doesn't work with MS Outlook Express. Very difficult to get support from developer. You have to Jump Through The Hoops and set up an account at his private forum. Enough already....


Er.. MS Outlook Express? do you realize this is browser extension?

Also, dunno why do you said it's very difficult to get support from me... i'm right here.

Very nice add-on.

Awesome Rated 5 out of 5 stars

This is freaking amazing. Our school principle can see all our emails on our school accounts so now I can have real privacy.

Fan. Freakin'. TABULOUS.

Thank you!

I have some minor usability niggles that I'll probably post elsewhere (if there is such an elsewhere for that), but this extension a splode my mind.

Why?and how can I fix it?

Simply works Rated 5 out of 5 stars

Works in any textarea. Very simple. Works as promised. Next step: add features without increasing complexity (tall order!). Thank you!

very nice add-on Rated 5 out of 5 stars

Hi Diego,

thanks for the very nice add-on :-)
I've one question concerning your add-on:
I've read that facebook will also save your messages which you don't send (i.e. you write something and then delete everything without sending it). Because of this, facebook might transfer my messages to their servers before I was able to encrypt it - is this correct?

Good Job! (and a question) Rated 5 out of 5 stars

Thanks Diego, a very good job, and very easy to use addon, I'll show it to my students.
I have a question: I take for granted that all encryption/decryption operations take place on the local machine, so that whatever packet sniffing takes place outside that machine, it will only see encrypted data. In other words, if the machine is safe (no keylogger and similar software), then all communications through this addon is safe. Am I right?


Hi Daniele,

Of course, all encryption/decryption takes place client-side.

You can point your students to the GitHub Repo[1] in case they want to check how it works.

Top app Rated 5 out of 5 stars

Simplicity is winning; always
Attachments are not encrypted.
Inline pictures in mail will not be decrypted.
Would be perfect with these enhancements.

Rated 5 out of 5 stars

Works great!

Would really like to see some extras, like:
- encryption for files
- a way to manage (or store) keys

very useful Rated 5 out of 5 stars

Easy to use and it works, 256-bit military encryption better than ssl, as long as you keep your password safe nothing can break it, I think with some additional features this addon might become a standard for all paranoid firefox users (like me)

Very good ! Rated 5 out of 5 stars

Excellent plugin for tech an non-tech.
We need one for android too.


Makes private email easy to use Rated 5 out of 5 stars

Encrypted Communication is so easy to use it finally makes private email available to tech-heads and non-tech-heads alike. Just install the add-on, write an email, right-click the message and type the previously agreed-on pass-phrase. EC is the first private email method I can recommend to both my tech-competent and not-so-tech-competent friends and family. It's no longer necessary that our email be readable by anyone who cares to snoop.
Note that this is private-key, not public-key, based; you and your correspondents have to agree on a key by some separate means.

The developer has been very responsive to issues and requests. I had an issue using EC with one email provider and in barely a day, it was working with them, too.

EC deserves your support, if only to let the powers that be know that people want their private communications kept private. This can only help speed the universal adoption of private email.

Almost perfect... Rated 5 out of 5 stars

The 1.3 version of this extension does not work on Google Plus but do work on usual text areas. So almost perfect.

Edit: The developer said it will be fixed in v1.5 so am changing to a 5 star. ;)

This review is for a previous version of the add-on (1.3.1-signed.1-signed). 

Thanks for the report, this has been already fixed for version 1.5 (1.4 is awaiting review atm)

Just One Small Thing.... Rated 5 out of 5 stars

I gave it a try. Very nice. But you made one error. The encrypt
takes place in a message box, and that is good. But the part
of the message you want to decrypt might not be in a message box.
In order to use decrypt you may need to copy the message to
a message box first. Set the program so that marked text
can be decrypted. A great program.

Hi FredMcD,

While the encryption needs to take place in some editable/message box, decryption does not. Basically, decryption could take place anywhere, otherwise it's a bug either in the extension or in the website who is (incorrectly) processing the encrypted message.

For example, version 1.4 (released a few days ago and awaiting review as of time of this write) fixed a issue under FB due the message was being split'ed in three sections, header/main/footer so the extension was unable to recognize it. So, i guess that's what you've noticed, either under FB too or some other site pre-formating the encrypted message as HTML.

Here is a quick example to test decryption, the password is your nick:

--- This message has been encrypted using eComm Mozilla Firefox Extension
--- You need to have this extension installed in your browser to decrypt it
--- https://addons.mozilla.org/addon/encrypted-communication/


--- End of Encrypted Message

There have been another test message for ages on the "Developer's Comments" section at the bottom of the add-on page, btw.

That said, letting it work over the selected text could be a good idea, but as long the former method works as it should there wouldn't be the need to select the text at all.

This is not a suitable object (SPAN) Rated 4 out of 5 stars

I was also getting this error also, but I have found two solutions that work.

1st — easiest way: When you compose a message, in the bottom right of the screen is a toggle triangle. Click on that, and one of the options is to use Plain Text. This completely eliminates the problem, and it stays on plain text, from one session to the next, so it's the better solution.

2nd way — a little trickier: When composing a message, select all the text in the message. Then in the bottom left of the compose window, right next to the Send button, is a button that is an A with an underline. Click on that, and a toolbar pops up. At the very right of this toolbar is a button that looks like a Tx. If you hover over it, it says "Remove Formatting." Click on that button, and the problem is solved, until the next time you compose a message.

Simple, useful, cool. Rated 4 out of 5 stars

This is a really cool and simple to use firefox add on. I left off one start because it isn't immediately clear to me what kind of encryption is being used. If I could easily tell which method is employed in this add on or if I could choose the method myself, this is easily a 5 star+ add on. Thank to the dev for making a cool and useful add on.
