About this extension
Tired of scrolling through endless modules meant for other campuses or batches on SLIIT Courseweb? The SLIIT Courseweb Cleaner automatically filters out the noise, providing a clean, personalized dashboard tailored exactly to you.
No analytics, no tracking, and no external data sharing. The extension strictly operates on your local machine and only communicates with a public GitHub repository to fetch open-source filtering rules.
- Smart Auto-Detect: Automatically guesses your campus and batch (Weekday/Weekend) to get you started instantly.
- Custom Keywords (Whitelist & Blacklist): Total control over what you see. Hide old syllabus materials or pin crucial assignments using custom comma-separated keywords.
- Cloud-Synced Configuration: Configure it once, and your preferences sync automatically across your signed-in Firefox browsers.
- Community-Driven Updates: The extension periodically fetches community-sourced filtering rules in the background, ensuring it always stays up-to-date even when SLIIT changes their naming conventions.
- Ghost Mode: Optionally fade filtered modules instead of completely hiding them, ensuring you never accidentally miss anything.
- Group ID Filtering: Focus solely on your specific subgroup (e.g., 0301).
- Manual Theme Toggle: Switch seamlessly between Light and Dark mode.
No analytics, no tracking, and no external data sharing. The extension strictly operates on your local machine and only communicates with a public GitHub repository to fetch open-source filtering rules.
