Review summary

Users find Mailvelope offers an easy and painless PGP experience with good Linux GnuPG support once configured. However, multiple reviews highlight poor documentation and manual setup steps for Linux integration. The extension replaces default webmail editors, which can be inconvenient, and requests broad browser permissions, causing privacy concerns among users.

Pros

Easy to set up and use, providing a painless PGP experience.
Supports integration with native GnuPG on Linux.
Recommended by some email providers like GMX for encryption.

Cons

Poor or unclear documentation on Linux installation and GnuPG integration.
Requires manual configuration steps on Linux to enable native GnuPG integration.
Replaces the default editor of webmailers, limiting user experience.
Requests extensive browser permissions that raise privacy concerns.

2025-07-03	Fi*****	Installation on Linux not really documented (have to dig though the GitHub wiki, nothing is documented regarding GnuPG integration on their website). Once GnuPG integration works, it pretends it cannot find the public key for a recipient (manual searching the key on keys.openpgp.org works flawlessly). If you somehow make it work, it basically replaces the editor of your webmailer with this plaintext editor (so you can't really use the default editor of your webmailer anymore). All in all I can't really recommend this extension. Either you trust your webmailer enough to give it your keys or just use a local mail client. If you still want to bother trying this extension, for Linux Mint/Ubuntu you can enable GnuPG integration like this: 1. install gpgme-json (it prentends to automatically set up the firefox native-messaging-hosts file for you, but that's a lie) 2. create the "native-messaging-hosts" config "/usr/lib/mozilla/native-messaging-hosts/gpgmejson.json" with the following contents { "name": "gpgmejson", "description": "Integration with GnuPG", "path": "/usr/bin/gpgme-json", "type": "stdio", "allowed_extensions": [ "jid1-AQqSMBYb0a8ADg@jetpack" ] } 3. restart firefox 4. mailvelope should now detect your GnuPG backend
