Firesync is a free Firefox Bookmark Client App which allows you to access your Firefox Bookmarks on your Windows Phone or Windows RT Device. At the Moment only read access is supported.

This software is in no way related to Mozilla.
If you have an old Firefox Sync Account where you can access your "Sync/Recovery Key" in the settings (Settings->Sync->Manage Account->My Recovery Key) please look in the Store for "FireSync Legacy" which still supports the Sync Key.
