[Pkg-privacy-maintainers] Bug#864733: Temporary fix

[u]

Hi!

the great news is that Georg Koppen and Nicolas Vigier from the
Torproject have been very helpful and created a temporary fix for this
situation. Nicolas even committed a pull request for torbrowser-launcher
to use the new URL to check for updates (see
https://github.com/micahflee/torbrowser-launcher/pull/279).

So thanks to them <333, this works again right now in
torbrowser-launcher 0.2.7 and once Micah Lee, the upstream author,
includes Nicolas' commit, we'll have this change in Debian, too.

Cheers,
Ulrike
