For some time, Firefox has had a feature called “Reader mode” which is wonderful when you’re reading a blog post or news story that you’d like to declutter. It removes most of the extraneous links and other sections of the page which aren’t part of the actual story you’re trying to read.
Starting with version 50 of Firefox, we now have a hotkey which will toggle reader mode. Just press ctrl+alt+R and, if it’s supported on the page which is open, reader mode will become enabled. Pressing the same hotkey turns reader mode off.
