Bare Blocker от gibbon joyeux

This extension helps you get a barer, lighter browsing experience by stopping images and fonts from loading without their consent
The Bare blocker extension, just like an add-blocker, prevents websites’ images and fonts from being loaded. To load desired images, you just need to mouse over them.

This extension was made for an ecological purpose as images and fonts are an important part of today's internet pollution and most of them are not required to make websites readable.

A whitelist can be filled to allow listed websites to load normally.
