FSF JavaScript guidelines picked up by Posteo Webmail

by Zak Rogoff Contributions Published on Feb 06, 2015 12:04 PM
Over the last few months, Webmail provider Posteo has been working with the FSF to license and tag all JavaScript on their Web site and Webmail system so that it is immediately identifiable as free software. They have also done everything possible to ensure that it is 100% compatible with the GNU LibreJS browser extension, which automatically blocks any potentially nonfree JavaScript, making it easy to browse the Web in freedom. This is an outstanding effort in defense of the freedom of Posteo's users, and the company deserves recognition for it. We hope others will follow their lead.

Posteo's work on this project started when Richard Stallman introduced the German company to the Free JavaScript campaign in 2014. The campaign promotes free JavaScript through the adoption of the FSF's human- and computer-readable JavaScript licensing standard, while offering implementation help from FSF staff and the skilled volunteers of its JavaScript Developers Task Force.

The collaborative process with Posteo actually uncovered some bugs in LibreJS, which are now being fixed. Once they are fixed and the site is re-tested, we will be able to announce Posteo's full compatibility with LibreJS. We just didn't want to wait to publicly thank them for what they have already achieved!

LibreJS's sole maintainer Nik Nyby is looking for help maintaining the growing project. To hack on LibreJS, start with the git repository and mailing list or contact Nik directly at If you have knowledge of free software licensing or JavaScript and want to help but are not interested in working on LibreJS at the moment, you can lend your expertise to the campaign by applying to the JavaScript Developers Task Force discussion list.

Stay tuned for more exciting announcements about Posteo and other sites soon! And if you'd like to send a social media "Danke schön" to @Posteo_de, we think they'd appreciate it. (Just make sure not to use proprietary software while doing it.)
