Remove URL tracking/encoding from Gmx.com and Mail.com

[2zzly]

Both sites track and encode urls in all emails this way:

https://deref-gmx.net/mail/client/ [11 digit alpha numerical identifier]/dereferrer/?redirectUrl=https%3A%2F%2F[URL you want to go to in URL encoded]

https://deref-mail.com/mail/client/ [11 digit alpha numerical identifier]/dereferrer/?redirectUrl=https%3A%2F%2F[URL you want to go to in URL encoded]

Hello and thanks for the suggestion!

[2zzly]

I've made two versions that accomplish this.

Tampermonkey user.js script:
https://greasyfork.org/en/scripts/473510-gmx-mail-com-outgoing-url-decoder

Html version:
https://github.com/2zzly/GMX-Mail-deref-decoder/blob/main/GMX-Mail-deref-decoder.html

Not sure how to integrate this into privacy badger repo.

Good to know, thanks for the links!

I'm not yet sure this particular first-party protection belongs in Privacy Badger. Basically, it does if enough users want it. Otherwise, this is probably best left to user scripts and extensions dedicated to link cleaning. So, let's keep this issue open and see if anybody else votes for it.
