Hold down the Alt key while clicking on a tab’s close button to close all other tabs and leave only the chosen tab open.
A neat little feature Vivaldi has is the option to close all tabs except one. There are actually more ways to do it than the one mentioned above, so, let’s go over all of them.
- Hold down the Alt key and click on a tab’s close button.
- Right-click on a tab and select Close Other Tabs.
- Type “Close Other Tabs” in Quick Commands.
- Create a Keyboard Shortcut or Mouse Gesture for the action.
For the last two, the tab you want to keep open needs to be the active tab.
