Please aware that the master-password only protects your passwords on that device - the choice of a master-password on one device has no bearing on how the passwords are stored on other devices connected by Sync. Further, your choice of master-password has no bearing on how the passwords are stored on the Sync servers - that is a characteristic of the strength of your Firefox Accounts password.

Hi, I'm aware of the difference between Sync Password and Master Password, keyword Firefox 34.

But password still aren't synced on my mobile.

Right so if a master password is set on the other device, to test it, if you temporarily disable the master password and do a Tools > Sync Now or tap Sync from the Accounts menu in your Android Settings, do they show up?

Sorry for my late response I did but no password sync in the beginning. Even resetting/removing the sync account hasn't worked out. Later that week I had trouble with my not android stock keyboard. Android was always switching back to the stock one even in the middle of the writing process. After some troubleshooting and several restarts it turned out that the xposed framework or some of its moduls was disturbing the system why ever (ongoing). Anyway the custom keyboard is now working and surprise surprise firefox synced all passwords. I don't no why, I will continue troubleshooting during the next couple of weeks and come back on this. All what I need to know (for the moment) is how to access the reading list of firefox android in the desktop version? Thx
