Hello ineuw, Please see these bug reports : https://bugzilla.mozilla.org/show_bug.cgi?id=1554742 and : https://bugzilla.mozilla.org/show_bug.cgi?id=1556890

Thanks McCoy, I will wait for a patch or a version upgrade to correct this. I imagine this could not have been a priority since it was first reported ten months ago.

Note that this only seems to happen if you use a Firefox build from the repositories. You can possibly switch to the official Firefox release.

cor-el, this is so until Firefox calls home and all settings become meaningless. If updates are not disabled by a policy file at startup, then most of my preferred settings are changed.

It is strongly suspected that the language issue originates in Linux Mint. I believe that the language settings are affected by the installer's IP address. Whether it's done by the softwares individually, or reading the settings from the OS, I don't know.

I forgot to mention that my FF windows installation file for Windows is from the https://ftp.mozilla.org/pub/firefox/releases/ repository, where I selected the en-US package, but had to block updates in the registry group policy.

I cannot install the Linux version because it's a tarball and I never succeeded to installing one. Something is always is missing. So, I am forced to install the en-US package from the firefox ppa, and that's where the "und" issue originated.
