Why is it so hard to find a browser extension that strictly does keyboard tab switching?

My browser tab bar gets messy quick and constantly using the trackpad to click around really slows down my workflow. I spent the afternoon looking for a basic keyboard shortcut extension to hop back and forth between active tabs.

Instead of simple hotkey tools everything on the Web Store feels like an over engineered workspace manager requiring full access to reading browser data.

What tiny privacy friendly extension do you use that handles basic tab cycling without any extra fluff?
