Hi For users of Android, we offer three versions of Firefox: Firefox, Beta, or Nightly. Firefox for Android is the finished product, with Beta and Nightly being early test versions. You get the chance to see and use new features before anyone else, just be aware there be one or two unreslved issues we are still working on. I think that the setting you need to change is at: # Tap the three line menu # Select '''Settings''' # '''General''' # Change the slider for '''Tab queue''' I hope that this helps, but if not, please come back here and we can look into it again for you.
