Tab management in Firefox Android should have like a tab bar with closing 'X' button to easily close and '+' button to open. Kind of like how Vivaldi does it in android. Or if not copying it here, then some gestures could also probably do it. Like swiping up in the tab button would open a new tab and swiping down will close the current tab. Also automatic closing of tab should also have time limit of one hour. Hope these improvements will get to see on Mozilla Firefox android very soon. Eagerly waiting. And can't thank you enough for Firefox.
