What Are Permissions in Firefox?

Like almost all great things invented by humankind, we've somehow managed to ruin the internet. Thinking of the hours you've wasted clicking through about twelve annoying pop-ups just to get to the content you want to view is enough to drive you insane. One of the most annoying pop-ups of recent years is the request by a website to send you notifications.

When you immediately click ‘block' in a rage, you're setting permissions for that website. The next time you visit that site in Firefox, your browser will remember that you don't want it to be able to send you notifications.

You can grant permissions for a huge range of different things, from the ability to access your webcam and microphone to whether or not videos on the webpage can autoplay. Firefox allows you to add or remove these permissions at any time, and in some cases will also give you the option to always be asked each time you use the site.
