add-on allows users to prevent websites from using some Javascript APIs to fingerprint them. Users can choose to block the APIs entirely on some or all websites (which may break some websites) or just block or fake its fingerprinting-friendly readout API.\n\n**IMPORTANT**: you should only have ONE addon/setting set that protects an API. Otherwise you could face massive performance issues. (E.g. EclipsedMoon for Palemoon has 'canvas.poison' which is known to cause issues: https://github.com/kkapsner/CanvasBlocker/issues/253#issuecomment-459499290)\nBut setting privacy.resistFingerprinting to true and/or using the new fingerprinting protection introduced with Firefox 67 is fine.\n\n-----\n\nProtected \"fingerprinting\" APIs:\n * canvas 2d\n * webGL\n * audio\n * history\n * window (disabled by default)\n * DOMRect\n * SVG\n * TextMetrics\n * navigator (disabled by default)\n * screen\n\nMore information on fingerprinting can be found at:\n * \u0026lt;canvas\u0026gt;: https://www.browserleaks.com/canvas\n * audio:\n   * https://audiofingerprint.openwpm.com/ (very poorly written = slow)\n   * https://webtransparency.cs.princeton.edu/webcensus/#audio-fp\n * DOMRect:\n   * http://jcarlosnorte.com/security/2016/03/06/advanced-tor-browser-fingerprinting.html\n   * https://browserleaks.com/rects\n * https://github.com/ghacksuserjs/ghacks-user.js/wiki/Appendix-A---Test-Sites\n\n-----\n\nBeta versions can be found at https://canvasblocker.kkapsner.de/versions/.\n\n-----\n\nThe different block modes are:\n * fake: Canvas Blocker's default setting, and my favorite! All websites not on the white list or black list can use the protected APIs. But values obtained by the APIs are altered so that a consistent fingerprinting is not possible\n * ask for permission: If a website is not listed on the white list or black list, the user will be asked if the website should be allowed to use the protected APIs each time they are called.\n * block everything: Ignore all lists and block the protected APIs on all websites.\n * allow only white list: Only websites in the white list are allowed to use the protected APIs.\n * block only black list: Block the protected APIs only for websites on the black list.\n * allow everything: Ignore all lists and allow the protected APIs on all websites.\n\n-----\n\nYou can contribute to CanvasBlocker by translating it and/or improving the translations.
