I have several accounts for the same login site. I saved these logins in Firefox for Windows. This then syncs to my Firefox on Android. In Firefox for Windows, when I am on the login page, I click on the user or password field and I get a list of the possible login users. When I select one the appropriate user and password are entered and I log on normally. In Firefox for Android this does not work. How can I select the user/password combination in Firefox for Android?
