Blue Blocker is a free Chrome extension developed by Liquid Nitrogen. As the name suggests, this add-on allows users to block all Twitter Blue verified users on twitter.com. With just a simple installation, you can bid farewell to all the paid blue checkmarks cluttering your timeline.

By default, Blue Blocker does not block users you follow or who follow you and have purchased Twitter Blue. However, you have the flexibility to change this and other settings from the extension's context menu, which can be accessed by clicking the extension icon in your browser's toolbar.

Blue Blocker offers a range of features to enhance your blocking experience. Its internal queue ensures that users are blocked in the background without hitting Twitter's API limits. You can also avoid blocking celebrities and influencers who were given Twitter Blue against their will. Additionally, you have the option to block anyone who promotes a tweet and supports this "nightmare platform."

The extension allows you to customize the speed at which users are blocked to avoid API limits. Syncing between tabs ensures that you can have multiple tabs open without any worries. The settings menu is simple and straightforward, allowing you to skip blocking people you follow or even affiliates. If you feel guilty about blocking, you can choose to mute instead.

Blue Blocker provides optional messages that inform you about the users you've blocked and even allows you to unblock them if needed. It also supports every major location where tweets show up, including search results, tweet replies and threads, your home timeline, and user pages. Additionally, you have the option to block users with NFT avatars if desired.

Endorsed by the popular Twitter personality @dril, Blue Blocker is a reliable tool for anyone looking to streamline their Twitter experience. You can also support or contribute to Blue Blocker's development on GitHub.
