Tab Wheel Scroll от Johndodev

Tab Wheel Scroll lets you navigate between browser tabs using your mouse wheel — no clicking on the tab bar required.

How to use

• Hold Alt and scroll up/down to switch tabs
• or hold the right mouse button and scroll up/down to switch tabs

Note: Your cursor must be positioned over the web page content (not over the tab bar itself).
✓ Also supports horizontal scroll wheels (e.g., Logitech MX Master 3).

Features

• Cyclic tab switching: wraps around from the last tab to the first (configurable via the extension popup)

Where it does not work

For security reasons, browsers restrict extensions on certain pages.
The scroll will skip:

• Internal pages (e.g., settings)
• Add-on Web Store pages
• Search results (e.g., Google Search) unless you have explicitly allowed the extension to access these pages in your browser settings.

On these pages, the tab is simply skipped.
