Bugzilla

Thanks for the report! This is either bug 1751153 or bug 1826330.

If you have Debian or Ubuntu, you can install Mozilla's experimental Firefox Nightly debian package (bug 1799516):
It has gotten a proper .desktop file today (bug 1824327) which solves this bug.

`$ curl -sSf https://packages.mozilla.org/apt/repo-signing-key.gpg | gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/packages.mozilla.org.gpg > /dev/null`
`$ echo "deb [signed-by=/etc/apt/trusted.gpg.d/packages.mozilla.org.gpg] https://packages.mozilla.org/apt mozilla main" | sudo tee -a /etc/apt/sources.list.d/mozilla.list > /dev/null`
`$ sudo apt update`
`$ sudo apt install firefox-nightly`

With `apt-cache search firefox-nightly` you can find out which language packs can be installed.
e.g. `$ sudo apt install firefox-nightly-l10n-de`

Disable the default browser check on about:preferences and don't use it (as it would create a faulty ~/.local/share/applications/userapp-Nightly-*.desktop file).
