Hey Miroslav,
If you run the latest 1Password 7 desktop beta app + 1Password X beta in your Firefox, the two should integrate and allow you to unlock using Touch ID. Here are the instructions: https://support.1password.com/getting-started-1password-x/#to-integrate-with-1password-for-mac

If it doesn’t work for you, please email us at support+extensions@1password.com and we’ll be happy to help you further.

Thanks for the five star review!
