Since Sync is broken on Android (many users are suffering from this!), there is NO possibility to save bookmarks on from mobile device. The only chance to get sync work again is to wipe Firefox completely so I will lost all bookmarks. Without an export function I have to manually do this for more than 300 entries. Exporting bookmarks was possible 20 years ago! So either fix the bogus Sync on Android or give the customers access to their data!
