About

This extension prevents default actions (forward/back history jumps) for mouse side buttons (4 and 5)

FAQ:
Q: Why do you need a permission to change contents for all websites?
A: Because it allows this extension to inject 5 lines of JavaScript code into webpages, preventing default mouse actions. You can verify the contents of injected code using dev tools (F12) -> Sources -> Content scripts (on the left side) -> FFMSB. Contents of this file are also provided in screenshots section because there's nothing else to take screenshots of :)

Q: IT DOES NOT WOOOOORK :((((
A: It does, except for 2 cases :)
 1. Chrome Web Store (extensions are not allowed to use content scripts here due to security reasons)
 2. Chrome menus, including the entire top bar (again, it's impossible to intercept shortcuts while your mouse is there) 

Q: Who is this made for?
A: For people who use these buttons in other applications running alongside Chrome - for example, in VOIP software as push-to-talk button
