Facebook Auto-Refresh Blocker, created by rhsCZ for Firefox, targets an annoying Facebook behaviour: unwanted feed reloads when you switch tabs. It prevents page reloads triggered by visibility changes, preserves scroll position, and offers a one-click popup toggle plus light/dark/system themes for simple control. The extension requires no account and installs without configuration. It is available for Firefox on Windows, macOS, and Linux. Desktop Facebook users who multitask across tabs gain uninterrupted browsing and preserved reading position.

It stops the feed reloads that break reading sessions

The extension intercepts Facebook's visibility signals to keep you on the same post. By targeting the Page Visibility API and related browser cues, it prevents reloads that occur after tab switches or idle periods. Installation is zero-configuration, so the blocker activates immediately and restricts its actions to facebook.com pages and subdomains rather than altering broader site behaviour.

Privacy is framed around minimal data handling and inspectability

The developer states the add-on does not collect or transmit user data. The extension executes its logic locally and requires explicit permissions to access browser tabs and facebook.com data so it can apply blocking. Users can review the source code on GitHub for transparency, which supports independent inspection of what the extension actually does.

Controls are simple, appropriate for users who want little fuss

Control is handled through a compact popup with a one-click on/off toggle. Theme options include Light, Dark, and System-sync modes inside the popup, and the toggle lets you pause protection without uninstalling. The interface avoids complex settings, which suits users who prefer lightweight, immediate control over granular configuration menus.

It fits desktop workflows but is intentionally narrow in scope

The extension runs on Firefox across Windows, macOS, and Linux, aimed at desktop multitaskers. Its single-purpose design limits effects to Facebook and excludes other social networks, keeping the implementation small. That narrow focus makes it a specialist tool for people who juggle many tabs rather than a general-purpose site-management extension.

Practical, inspectable utility for tab-heavy desktop Facebook users

The extension is a practical choice for desktop users who juggle many tabs and want predictable behaviour; its MIT license and client-side execution make the code auditable and behaviour consistent. The primary constraint is browser exclusivity: it runs only on Firefox and applies specifically to facebook.com pages. For anyone seeking a narrowly focused, inspectable way to reduce feed interruptions, the extension suits that need.
