Say a webpage isn’t loading right. Maybe it’s collapsed from too much traffic after going viral on Reddit. Maybe it’s blocked in your country thanks to a law like GDPR. Maybe it was recently deleted. Usually Google has a saved copy of that page. And the quickest way to get that saved copy is to type cache: in the address bar.

Firefox unveiled a handful of new features this week via its Test Pilot program, and two caught our eye: A new Side View that allows you to view two sites within the same window side-by-side, and Firefox Color, a feature that allows you to aggressively customise your browser's colours.
