Dozens of open tabs in Firefox on iPhone can slow the app and make it hard to find anything. Firefox can close them all at once instead of swiping each one away. The exact button location has changed between versions, so look for Close All Tabs in the tab view or the tab button’s menu.
Quick Answer
Press and hold the tabs button (the square with a number) and tap Close All Tabs, or open the tab view and use its menu to close all tabs. Confirm when asked.
