Diễn đàn hỗ trợ Firefox

To sync a mobile device, the instructions say to open Firefox browser on mobile, from Menu go to Sign In, aim phone camera at QR code. The 3 lines at the screen bottom right (i'm assuming this is a menu but printing an icon labelled "menu" is less cryptic) offers no sign in opportunity.

Dear support, I have 2 pcs and I need to enter sync password every time I open Firefox - start notebook. It works fine on the second pc and password is remembered. How to solve it? Because I need to write sync password every time, open all cards etc .. OS - win11 pro, Firefox browser versiono 145.0.2 64bit, no 2FA in firefox. Thank you. Mike Hrubjak.
