JShelter: Chrome Extension for Improved Browser Security & Privacy

JShelter is a crucial Chrome extension that significantly improves your web browsing security and privacy. Acting like a firewall, it controls the browser's APIs to restrict the data they can access and send out to web pages, thus preventing malicious tracking and fingerprinting. Users also have the added control to permit certain sites while adding restrictions, further enhancing their online security. This extension proves to be a strong defense against potential attacks on browsers, operating systems or hardware.

Great addon!

Michael A, 2025-01-12

t's incredibly and unnecessarily complex. The notification pop-ups can't be stopped without being a developer or advanced knowledge of the extension which is incredibly frustrating. The slider options for manual adjustments are useless, they are for information purposes only even when in Chrome extension Developer Mode. Also, unlike the now malware ridden Fingerprint Spoofing extension, JShelter randomly spoofs your GPU instead of just stating "Unknown" at the recommended setting. The number of CPU cores can't be blocked even if you use a custom setting. Basically, you're stuck with the various presets unless you create your own custom level. And given what happened with Fingerprint Spoofing and other extensions (infected with malware), you should continuously back-up (pack extension) of all the extensions you feel are critical. However, if Google flags your extension, it disables it permanently.

Благодарность разработчикам. Правда, поднагружает процессор (это неточно, проверьте)
