Browser extension for OpenPGP decryption of an e-mail in Gmail

Question

I sometimes received emails on Gmail that people encrypted using my OpenPGP public key. I am looking for a browser extension that can:

decrypt e-mails in Gmail using my OpenPGP private key (e.g. automatically or by clicking on some "decrypt" button -> I don't want to have to copy-paste somewhere as I currently do)
work within the Gmail interface (e.g. I don't want to have to POP/IMAP)

and if possible:

Not a duplicate, but broader: OpenPGP encryption/decryption of webpage content — unor, Mar 14 '14 at 12:01
Well the linked question is indeed boarder in terms of features, but stricter regarding software license and supported browser+OS. — Franck Dernoncourt, Mar 14 '14 at 14:47

Mymail-Crypt for Gmail™

Integrates with the GMail interface
You can decrypt e-mails with a "decrypt" button
gratis
Works with Windows 7
"This project is no way affiliated with Google™."

The project is powered by OpenPGP.js. OpenPGP.js aims to fully implement the RFC 4880 OpenPGP standard. This project is still a work in progress, but supports a variety of key importation/generation abilities to encrypt and decrypt messages. Please see http://openpgpjs.org/ for details on this project.

According to the linked page it's in alpha, not beta. Not that it makes much difference... – nidunc Jun 4 '14 at 11:08
