Font Fingerprint Defender

Canvas Fingerprint Defender

Canvas Fingerprint Defender is a lite extension that lets you easily hide your real canvas fingerprint by reporting a random fake value. According to many tech blogs, completely blocking canvas fingerprints is not a good idea, therefore reporting a "fake" fingerprint could be the best solution to better protect your privacy. This addon simply adds a small noise to the actual fingerprint and "renews" it every time you visit a website or reload a page. It is important to note that, it does not have any settings or options to adjust. Simply add it to your browser and start surfacing the internet. If you want to test this addon, please visit a website that shows your fingerprint (i.e. browserleaks). Every time you reload the page, you will see a new fake fingerprint. To report bugs, please visit the addon's homepage (https://mybrowseraddon.com/canvas-defender.html) and fill out the bug report form.

Canvas Blocker - Fingerprint Protect

This browser extension safeguards user privacy by preventing malicious scripts from using the HTML canvas element for user fingerprinting. It introduces slight changes to the data generated by the canvas element when specific methods are invoked, rendering it unusable for fingerprinting. In comparison to similar extensions, this one is lighter and employs a more efficient method to obstruct fingerprinting across all frame elements (top and subframes). The extension operates in three modes: 1. Random noise 2. Random noise (per page) to maintain a consistent identity within the current page session 3. Fixed noise to sustain a constant yet unique identity continuously Key Features: 1. Minimal footprint fingerprint defender 2. Ability to block or disable fingerprinting on specific hostnames 3. Notification when canvas fingerprinting is detected 4. Option to disable notification for select or all hostnames 5. Compatibility with cross-origin (CORS) and sandboxed iframes (such as Disqus and Hangouts) Notes: This extension doesn't entirely block the canvas element. Instead, it modifies two methods to prevent the JavaScript engine from creating a unique identification key from this element. What is Canvas Fingerprinting: Canvas fingerprinting is a method among several browser fingerprinting techniques used for tracking online users. It enables websites to identify and monitor visitors by leveraging the HTML5 canvas element rather than browser cookies or similar means. This technique functions by exploiting the HTML5 canvas element. When a user visits a webpage, the fingerprinting script initially writes text using the preferred font and size and adds background colors. Subsequently, the script calls the Canvas API's ToDataURL method to retrieve canvas pixel data in dataURL format, essentially a Base64 encoded representation of binary pixel data. Lastly, the script hashes the text-encoded pixel data, creating a unique fingerprint.

Ping Blocker

Prevents sites from tracking you by blocking the PING request! Ping Blocker helps you prevent websites from tracking you by blocking ping requests. Ping requests can be generated via a few methods on websites. The most famous one is the navigator.sendBeacon() API. Another method is to use the "ping" attribute for anchor elements. The last method is via a tag with a "report-to" URL. This addon, when enabled, can successfully block all ping requests. Toolbar icon changes color when you click on it. The red color is when the addon is active and the grey color is for the inactive state. Within the add-on options page, there are several settings to adjust. You can choose which type of ping request to block via the first three options. Next, there is a console log error checkbox (to log blocked URLs to the browser's console). The last setting is for adding domains to be whitelisted. All entries should be comma-separated. If you have a feature request or found a bug to report, please fill the bug report form on the addon's homepage (https://mybrowseraddon.com/ping-blocker.html).
