If you accidentally closed a tab, it is very easy to reopen it. Here are the methods to use for the main browsers.
Are you browsing multiple websites at the same time? So you’ve probably inadvertently closed a tab one day when you still needed it. If you are not in incognito, you can easily restore the tab you just closed. The first solution is to use the key sequence
Chromium
Right-click on the title of one of the open tabs and click on the option Reopen the closed tab in the context menu.
Firefox
Like on Chrome, you can just right click in the browser bar and then select Unclose tab.
Firefox also offers a more complete function: if the menu bar is not present at the top of the window, click with the right button in an area at the very top, then on Menu bar in the context menu. Click on the menu Historical, then on Recently closed tabs. You can then choose a tab to restore, or even all tabs.
Edge
As with Chrome, right-click on the title of one of the open tabs, then on the option Reopen the closed tab in the context menu.
Safari
In the tab bar, click on the symbol + which is used to open a new tab in Safari and keep the button pressed for a few seconds. The list of recently closed tabs is then displayed.
Opera
Click on the icon Tab menu located at the top right of the window, near the closing cross.
You then open a menu that shows the tabs currently open, but also those recently closed.
