Dear Javad,
Thank you for providing this information! I’ve set up the locale in Pontoon and have added you to the Team as Team Manager. You can find the team page here:
Right now only the Terminology project is enabled, but you can use the REQUEST MORE PROJECTS field to request a project to translate.
Please see the thread below regarding localization of Firefox for Desktop.
This note in particular:
From a contributor’s perspective, Firefox is a challenging project:
It relies heavily on the CLDR database for internationalization (dates, plural forms, etc.), and smaller locales might not be supported there.
Specifically, Firefox currently has an issue for right-to-left languages being displayed incorrectly as left-to-right if they are not part of the CLDR. This may take some time to resolve, so I would encourage you to consider another project such as Firefox for Android which I mentioned in my previous post.
Thanks again and please don’t hesitate to reach out if you have any questions.
Best regards,
Bryan
