I have several machines running either Linux, MacOS or Windows. I have Firefox running on all of them, which means that I can seamlessly switch computers. Apart from 1Password, that is, which behaves differently on each machine/OS combination. The worst of these is the present machine - running Linux 22. I have tried many times to reinstall Firefox and reinstall 1Password as an add-on. Although the add-on is installed, the icon is not displayed. When I come to a page that requires a password, I see the icon in the password entrybox, telling me to click the non-existent browser icon. Very frustrating. It's not the only problem I have with 1Password, but it's the biggest.
