Extension not available in Chrome Web Store

[guilhermebene]

I had been using this extension on a project for a few years. Now it seems the Chrome Web Store version is not available anymore (I get a 404 error when trying to access the extension page). You can check this at the following link: https://chrome.google.com/webstore/detail/pflmllfnnabikmfkkaddkoolinlfninn
Does anyone know if this is a temporary issue with Google's servers or has the extension been removed?
In any case, I was wondering if there is a way to install the extension directly from its source code, I'd appreciate if someone could help me with that.
