## Description

Mutable is an open-source Chrome extension designed to improve your web browsing experience by allowing you to mute unwanted content using custom keyword filters. It works across multiple popular social media platforms including Twitter/X, Facebook, Mastodon, Reddit, and Bluesky. Users can select keywords they wish to mute and choose how to handle such posts — blur them, blur with a preview, hide completely, or even replace them with adorable images of kittens, puppies, or hedgehogs for a more pleasant feed.

With Mutable, you gain full control over the content you see, enabling a more enjoyable and personalized online experience. Still actively developed, Mutable welcomes feedback from its users to improve functionality and support more sites in the future.
