Firefox Split View displays two tabs side by side in one browser window. In Firefox 149 or later, right-click a tab and choose Add Split View, then select a second open tab or enter a web address in the other pane.
How to open two tabs side by side
Mozilla documents Split View as available starting in Firefox 149. It places two tabs in side-by-side panes within the same Firefox window. You can start with one tab or pair two tabs that are already open.
Start with one tab
- Right-click the tab you want to keep in the left pane.
- Select Add Split View. The right pane will offer your open tabs.
- Choose a tab, or select the right pane and enter a website address in the address bar to open a different page.
Pair two existing tabs
- Select both tabs in the same Firefox window.
- Right-click either selected tab and choose Open in Split View.
Mozilla also documents an alternative: hold Alt on Windows or Option on macOS while clicking another tab from the active tab. See Mozilla’s Split View instructions for the current workflow.
Resize, swap, or separate the panes
- Resize: Drag the vertical divider between the two panes.
- Swap sides: Use Reverse Tabs in the Split View controls.
- Return to separate tabs: Choose Separate Tabs.
- Close the pair: Choose Close Both Tabs. Closing either tab in the pair also ends the split view.
What Split View can and cannot do
Each Split View contains two tabs. Mozilla says you can create an unlimited number of split views, but pinned tabs cannot currently be added to a split view. If you use Find in Page, it searches only the active pane, not both pages at once.

Split View also interacts with tab groups according to which tabs are active and selected:
- If the active tab is in a group, the split view is created in that group.
- If the active tab is ungrouped and the other selected tab is in a group, the grouped tab is removed from its group; the split view is created where the ungrouped tab was.
- If the selected tabs are in different groups, the split view is created in the active tab’s group.
Will Firefox restore a split view?
Firefox restores split views with a restored window when Open previous windows and tabs is enabled, and when you reopen a recently closed window. Reopening closed tabs with Ctrl+Shift+T on Windows or Linux, or Command+Shift+T on macOS, does not restore the split view.

When to use Split View instead of separate windows
Split View is useful when you want to compare or reference two pages without managing two Firefox windows—for example, comparing product details, following a travel itinerary while checking a map, or reading a source while taking notes in a web app. Separate windows may suit you better if you need to arrange pages independently across multiple displays or want each page to have its own window controls. Split View’s divider gives you a quick way to adjust the space each page gets, while its controls keep the paired tabs together or separate them when you are done.
