No I don't know, how does it work ?
Is there a special category for Amber's translations ?

@Cyberdom , you need to Register (create an account, there is no cost) at https://kodi.weblate.cloud , and once you do, go to this forum thread: https://forum.kodi.tv/showthread.php?tid=363132 and request to be added to the French language translators.  Please provide the account name you used to sign-up in weblate.

Once you have been added to the French translators, when you sign in to weblate, you can browse the available projects; one of those is kodi skins, and in there is skin.amber.  Once in Amber, select the language that you want to translate (in your case French (fr_fr)), and you will see a screen that shows what percentage of the translation is completed.  There is a Translate button there, when you click it, you can start translating.  Weblate will bring you the first string that is not translated, and you go from there.  It is very intuitive.
