Features & Capabilities

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.

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.

Is SLIIT Courseweb Cleaner Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

SLIIT Courseweb Cleaner requires very minimum permissions.

Risk impact analysis details

High Injects scripts into web pages, which may alter or extract site contents, resulting in a substantial risk.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

SLIIT Courseweb Cleaner is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
