Keybase

A secure chat button for every profile.

Keybase for Firefox is an official Keybase extension for composing ENCRYPTED messages to any Twitter, Facebook, Reddit, HackerNews, or Github user, from the convenience of your browser. It's an easier chat, and it's end-to-end encrypted.

This works even if they have yet to join Keybase. The quick summary:

• Everyone with a social network account has a Keybase inbox, even before they join Keybase • You don't need to know the recipient's email address or phone number or Keybase username—just a social media username is enough • No one (at Keybase or the social networks) can read your private exchanges • Look for the "Keybase Chat" button on profiles around the web • Toggle specific features in the extension options

At no point in Keybase's protocol does Keybase ever have the keys necessary to read your messages. This is end-to-end encryption, powered by the convenience of public social media usernames.

Keybase is open source, and so is this extension: • https://github.com/keybase/client

You can find the recent changes for the extension in the history of the "browser" directory.

A useless add-on for a useless site. The underlying idea is good, but the implementation is terrible. Everything is tied to their website, which is rarely accessible or stable. And even if everything is fine with the site, the software itself is full of bugs. Let’s add to this the “security” policy (due to which, in the event of critical failures, it is faster to create a new account than to wait 5 days or longer if you need an answer on Github) and the result is a completely unacceptable product.

Extension safety

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Keybase requires a lot of sensitive permissions. Exercise caution before installing.

Risk impact analysis details
  • Critical Request access to the following domains: {{requestedDomains}}
  • High ******* ******* **** *** ****** ***** *** ***** ** ******* **** ********* ********* ** * *********** *****
  • Medium *********** ************* ******* ********** *** ****** ************* ******* *** **** ** ******* **********
Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Browser Add-ons, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Keybase is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.

Risk likelihood analysis details
  • High This extension has low user count. Unpopular extensions may not be stable or safe.
  • Low **** ********* *** ******* **** **** * ****** **** ***** ******** *** **** ****** ** ** ****** *** *****
  • Low **** ********* *** ***** **** **** * ****** **** ***** ********** *** **** ****** ** ** ****** *** *****
