6 Today, we are retiring the *Tails Verification* browser extension that
7 used to be advertised on our download page. We are replacing it with
8 similar JavaScript code that now runs directly on the page.
10 This new verification procedure is:
12 - Simpler and faster for first-time users
13 - Compatible with more web browsers, for example, Edge and Safari
14 - As secure as the *Tails Verification* extension
16 From the logs on our website, it seems like only a minority of downloads are
17 currently being verified. We believe that this simplified verification procedure will
18 greatly increase the number of downloads being verified and improve the security of our users.
20 Users of the *Tails Verification* extension can safely remove it from their
21 browser. They will be reminded to do so on the download page.
23 We will remove the *Tails Verification* extension from the Firefox and Chrome
26 The other 2 verification techniques are still available:
28 - If you download Tails using BitTorrent, your BitTorrent client
29 automatically verifies the checksum of the Tails image when the
32 - If you know OpenPGP, you can verify your Tails image using an OpenPGP
35 Special thanks to [Mike Meixler](https://www.meixler-tech.com/) who donated his
36 time to help us with the verification JavaScript!
38 In the future, this simplification will allow us to further simplify the
39 download page and installation instructions. We also want to research how to
40 make the verification faster. If you know WebAssembly, see if you can help us
41 [speed up the checksum computation](https://gitlab.tails.boum.org/tails/tails/-/issues/16905).
