Is FFMSB (Freedom for mouse side buttons) safe?

Clean risk

This extension blocks Chrome’s default back and forward actions from mouse side buttons.

It injects a small content script into webpages to prevent mouse buttons 4 and 5 from triggering browser history navigation. The description notes it does not work on the Chrome Web Store or in Chrome menus and the top bar, where content scripts or shortcut interception are not available.
