Step 1: Open Microsoft Edge browser on your computer and in the address bar, type the following address:
Step 2: On the page that opens, the flag for hiding the title bar will be highlighted. In the drop-down menu just next to it, select the “Enabled” option.
Step 3: After making the changes, you will be asked to restart the browser. Once you do that, the changes will be in effect.
Step 4: When the browser re-opens, click on the top left icon alongside the tabs and select the option “Vertical Tabs” from there.
You will now see the title bar disappear and the tabs will be shown vertically on the left-hand side in a totally new interface. Vertical tabs have existed in Edge browser for quite a while, the disappearance of the title bar is something new.
