Please refer to the instructions provided in [[Using Tabs on Firefox for Android#w_view-and-reopen-previously-closed-tabs|this]] section of the KB article - '''Using Tabs on Firefox for Android''' After you select "Recently closed", you need to select "RESTORE ALL" to recover all your tabs. Note that this doesn't work in below cases: # "Quit" button is used to close the Firefox app. This button is available in the Menu (''at the top-right corner'') only if "Clear private data on exit" setting is enabled in ''Menu > Settings > Privacy'', although it's not enabled by default. # The Firefox app was removed from the Android's "Recent apps" screen.
