Have an easy way to use or discover Tails OpenPGP Applet from applications like the browser (context menu))

It’s not so easy to know that the OpenPGP Applet exist, and how to use it.
The doc is great, but maybe it could be nice to havean easy way to use or discover it from Iceweasel.

Let’s have a look on differents implementations.

A

Have a right-click on encrypted mail, so when you use a webmail to decrypt :

- you select your text in your webmail

- you right click “decrypt with passphrase”
- and then the normal OpenPGP Applet pops up.

Seems difficult (from irc) :

- “would need a browser plugin. lot’s of work”
- “would be hard to keep working once we sandbox the browser”

B

But maybe a browser plugin that just says that’s it’s possible with no programatic relation with other software :

- you select your text in your webmail
- on your right-click you have a "You can decrypt this message using the Tails OpenPGP applet, you can have a look to the doc

C

Maybe it’s not the most effective way to do it, a browser plugin could maybe :

- scrap the webpage

- see if there is any pgp encrypted text
- modify the page to say to the user that he can decrypt it using the applet

Maybe I should have a deeper look to https://tails.boum.org/doc/encryption_and_privacy/FireGPG_susceptible_to_devastating_attacks/index.en.html to understand at wich step it’s problematic on a security level. I think that we had a kind of C during the transition between FireGPG and OpenPGP Applet.
