Recently the user interface of Facebook has changed, and regarding my screen resolution, every button seems huge, and the whole thing looks too much "touchscreen friendly" - but on my laptop, it is very inconvenient and annoying. I would like to teach Chrome to resize this certain website to 80% of its original size. Resize should be performed any time (/only when) this specific website is accessed in a tab or window.
What are your suggestions? I also accept any suggestions using other browsers or extensions/addons to them.
