Tab Mix Plus add-on for Firefox has a handy feature where in you can switch to previous and next tabs by scrolling your mouse (with the cursor on tab bar) up and down respectively. We can achieve the same in Google Chrome using AutoHotKey.

1. Download AutoHotKey and install it if you don’t have it already.
2. Save this small ChromeTabsScroll.ahk file (the contained code can be found at the bottom of this post) and place it anywhere in your computer. Double click this .ahk file.
3. You may need to adjust the number in line 12. This is the height of Chrome’s tab bar.

That’s it. Now you can take your mouse over the tab bar at the top of Chrome and turn your mouse wheel forward and backward to switch to previous and next tab.
