Check Links Instantly with URLChecker
Overview
URLChecker is a Firefox browser extension designed to streamline the process of verifying the online status of file-hosting links. It supports a wide range of platforms including MediaFire, RapidShare, DepositFiles, Mega.co.nz, AdFly, Bitly, URLCash, and LinkBucks. The tool is particularly useful for users who frequently encounter or manage links to downloadable content across the web. By integrating directly into Firefox’s interface, it enables quick checks without leaving the current browsing session.
Target users include content curators, digital archivists, webmasters, and anyone who relies on reliable file links for research, downloads, or content distribution. The extension operates by validating whether a link is active or broken, helping to prevent wasted time on dead links. It is developed by URLChecker, a service provider focused on link integrity and online validation, and is hosted under the domain urlchecker.net. The tool is available at no cost, making it accessible for both individual and professional use.
Real-world applications include verifying links in forum posts, blog articles, or social media content before sharing or downloading. The extension also supports batch validation of multiple links on a single webpage, enhancing efficiency during content audits or site maintenance tasks.
Key Features & Capabilities
- Context Menu Integration – Right-click on any highlighted link to instantly check its status. This feature allows users to validate individual links with minimal effort, ideal for one-off checks during browsing.
- Status Bar Icon – A dedicated icon in Firefox’s status bar enables automatic scanning of all links on the current page. This is especially helpful when reviewing long articles or web pages with multiple file-hosting URLs.
- Multi-Platform Support – Compatible with major file hosts such as MediaFire, RapidShare, DepositFiles, Mega.co.nz, AdFly, Bitly, URLCash, and LinkBucks, ensuring broad utility across different content-sharing platforms.
- Link Extraction & Validation – Automatically identifies and checks the validity of links within selected text or on a webpage, reducing manual effort and increasing accuracy in link verification.
- Real-Time Status Feedback – Provides immediate visual feedback on link status, helping users determine whether a link is active or inaccessible without opening it.
These capabilities are particularly effective in scenarios such as content moderation, website maintenance, or preparing downloadable resources for distribution. The extension enhances workflow efficiency by minimizing interruptions and reducing the need for external tools or manual testing.
User Interface, Workflow & Performance
URLChecker features a minimalistic interface that integrates seamlessly into Firefox’s existing UI. The extension adds a small icon to the status bar and a new option to the context menu, both clearly labeled for intuitive use.

Workflow efficiency is high, as the tool requires no setup or configuration. Once installed, it functions immediately.
