Mouse4 Go Back Block

Mouse4 Go-Back Block
Stop your browser from navigating back every time you press the Mouse4 button.

This lightweight extension blocks the "go back" action triggered by your mouse's side button - also known as the back button, thumb button, button 4, or XButton1 - so an accidental press no longer throws you off the page you're on.

Why you might need it:
- Push-to-talk: If you use Mouse4 as your push-to-talk key in Discord, TeamSpeak, Mumble, or other VoIP software, this stops the browser from jumping back mid-conversation.
- Accidental presses: Perfect if you keep bumping the side button and losing your place on a page or in a form you're filling out.
- Everyday browsing: Keep your side button free without it hijacking your navigation.

How it works:
- Once installed, the extension quietly intercepts the back-navigation that the Mouse4 / side button would normally trigger.
- There's nothing to set up - install it and it just works. Your forward button and all other mouse functions are left untouched.

Lightweight and private:
- The extension is tiny (under 20 KB) and collects no data whatsoever. No tracking, no accounts, and no permissions beyond what it needs to do its one job.

Please note - protected pages:
Chrome prevents extensions from running on certain pages, so go-back blocking will not work on:
- chrome:// and chrome-extension:// pages
- The Chrome Web Store
- PDF documents
- Pages with JavaScript disabled
- Security warning pages and error pages (404s, network errors, etc.)
- view-source: and data: URLs
