I use LastPass on desktop and in Dolphin browser on Android, but it mystifies & frustrates me in Firefox on Android. I have the add-on and the Android app installed, I sign in on the Android app, then go to a webpage (egAmazon sign-in page). I pull down the 'hamburger' menu from upper right, click on LastPass, and click 'autofill forms'. It asks for my credentials, I enter them and then ...nothing happens. What should happen? What am I doing wrong? I have just uninstalled & re-installed the latest Firefox, on a Nexus 9 tablet running Android Marshmallow (6.0 Build MRA58N) Thanks in advance.
