Convenient simple add-on for doing one thing. If you happen to need to scroll between tabs using your mouse, this seems to be a great option. I was hesitant to install it because it didn't have any reviews but I took my chances and I am glad I did. It does work! I messaged the author with some suggestions and he implemented them at once, I think that shows the level of commitment and I hope the extension will be maintained and improved over time!
