Tahir is a free Chrome extension designed to help users maintain modesty while browsing the internet. Aimed at filtering out impermissible images and videos, it automatically blurs these elements on any website visited. This feature is particularly useful for individuals seeking to avoid inappropriate content in an increasingly permissive online environment.

The extension allows users to temporarily disable its filtering by pressing "Alt+L" or selectively reveal specific images by hovering over them and pressing "Alt+K." Additionally, Tahir offers the option to permanently whitelist safe websites, ensuring a tailored browsing experience. Notably, the extension respects user privacy, as it does not track browsing history and is open source, allowing for transparency in its operations.
