A browser extension to block posts by anonymous users on 9GAG

About

This is a browser extension that allows you to hide posts made by anonymous users on 9GAG.

Motivation for this is that it's not possible to block anonymous users and thus your stream gets cluttered with low-quality content.

As a solution this extension allows you to just hide all posts made by anonymous users. For this the extension adds a new button to the header navigation:

When you click on it all posts made by anonymous users get collapsed in your stream and the button's icon changes:

Enjoy your anonymous-free 9GAG stream!

Known Bugs & Limitations

Unfortunately completely hiding or removing the anonymous posts will screw up scrolling using the keyboard shortcuts J and K. Therefore the blocked posts are "hidden" by restricting their height to 40px. This means those posts are still part of the stream but only their header is visible.

But this also means that scrolling using the keyboard shortcuts J and K will stop at these collapsed posts, too. This may give the impression that scrolling to the next post didn't work correctly.

If anyone knows a better solution for this issue, please see below on how to contribute.
