Bluhell Firewall is a lightweight browser extension designed for Firefox, focusing on performance while blocking unwanted online resources. Unlike traditional ad blockers that come with a myriad of features, Bluhell Firewall adopts a minimalist approach by utilizing only seven hard-coded blocking rules. This results in a compact size of just 30KB, significantly lighter than other popular ad blockers that can exceed 700KB. With the ability to block around 8400 domains, it effectively filters out unnecessary content without the bloat.

The extension aims to enhance browsing speed by simplifying the blocking process. Users can easily toggle the extension on or off via the toolbar button on desktop or the menu on mobile. This straightforward functionality makes Bluhell Firewall an appealing choice for those who prioritize performance over configurability, offering a no-frills solution to unwanted online distractions.
