Hello,

Depending on the app it should have its own back button. Could you let me know which app you are having trouble with?

I've attached a screenshot of the Settings app in Firefox OS. The screen shows the Sound settings page. If you wanted to go back to the main screen of the Settings app you would click on the back button in the top left hand corner. It looks like this: <

Some apps (e.g. from the adaptive app search screen) may not have a back button built into the app itself. In that case you can access a back button from the navigation bar at the bottom.

I've attached another screenshot from the IMDB app. Here I have accessed the 'Breaking Bad' page. If I want to return to the previous screen I can swipe up from off the screen over the orange button in the bottom right hand corner. It looks like this: ᶺ

Then the navigation bar will appear (see my 3rd screenshot). The back button is on the far left side of the navigation bar. It looks like this: ←

I hope this helps. Let me know if not.

Currently all the pre-installed apps have the back button. But the Facebook app does not have a back button and its not possible to go back to the previous page. And this is just one of the many apps that have this problem!
