Extremely finicky and buggy extension. A year and many versions later, Touch ID STILL randomly goes away as an option to open the browser extension, not on only on Firefox but also on other browsers. I used to have to open the desktop app to open or use the extension, or disable then enable the extension. Now doing so doesn't help. And yes, Touch ID is selected in settings. What's the use of th Touch ID option if it randomly doesn't work? The extension is good when it decides it wants to work.
