Merge All Open Windows Into Tabs Within Safari
If you’re like me you tend to have a million browser windows open at the same time, which can make it really difficult to keep track of sites that are open and finding things can be difficult. Thankfully Safari has a great feature that lets you merge all these open windows into tabs within a single window.

To do this:
- Pull down the Window menu and then select “Merge All Windows”
That’s all it takes, Safari will do it’s magic and merge all the open windows into tabs, even if the open windows have their own tabs.

Leave it to Apple to build in an elegant solution to a common problem. You can drag tabs from one window to another in Chrome, but as there is a general lack of menu items in Chrome it could be a bit time consuming if (for whatever reason) you had many multiple windows instead of tabs in a single window.
I love the Merge All Windows shortcut. You can also create a keyboard shortcut for this by going to ‘System Preferences’, click on ‘Keyboard’, then ‘Application Shortcuts’. Hit the ‘+’ button, choose ‘Safari’, create a Title and add your preferred keyboard combination (I use ‘⇧ + +M’).
