Doesn't work on Linux.
EDIT: Got it to work by removing the extension and adding it again. I think the extension needs to be installed AFTER installing the app. Installing the app afterwards did not seem to fix the non-working extension.

I rated this 5 stars. Because it works on Android Firefox and Desktop Firefox. This is a feature I need and therefore cannot use Lastpass or other competitors. As far as I can see 1Password has best cross-platform/cross-browser/cross-device. This is such a good feature. Thank you. You have earned a paying customer after my trial is done.

1Password is dedicated to privacy, and a commitment to protecting your information by not keeping your information. This is what all secure password managers should do. Other password managers are poor defenders of your data compared with 1Password.

1Password is one of the most highly respected password managers in the security community.

The new browser add on is fantastic, integration with Touch ID makes the whole process easy and seamless. Bumping rating up from four to five stars.

Been relying on 1Password for years. I keep everything personal in its database. It is simply THE BEST.
