You're logging into both with the same firefox account email right? Sorry if this is a dumb question. It might be making separate profiles so they can't see each other, or something similar. Do you have sync turned on?

Yes I,m useing the same email, sync i,ll check its on. Whats a proposal of sollution ? Its normal to use the same email why should I made a new one ??

Firefox uses a Firefox Account to connect to Sync, so to make this work properly all connected need to use the same Firefox Account because otherwise data cannot be merged to other devices.
