 - The {{domxref('WebGLRenderingContext.drawingBufferColorSpace', 'drawingBufferColorSpace')}} and {{domxref('WebGLRenderingContext.unpackColorSpace','unpackColorSpace')}} properties of the {{domxref('WebGLRenderingContext')}} and {{domxref('WebGL2RenderingContext')}} interfaces are now supported. These specify the color space of the WebGL drawing buffer, and the color space to convert to when importing textures, respectively.

 Browser vendors know that users don't like the behavior described above, and as a result have all started to block third-party cookies by default, while also including exceptions and heuristics in their source code to work around long-standing third-party cookie issues with popular websites.
 
-- Mozilla's [Anti-tracking policy](https://wiki.mozilla.org/Security/Anti_tracking_policy) has led to Firefox blocking third-party cookies from known trackers by default (see [Firefox tracking protection](/en-US/docs/Web/Privacy/Firefox_tracking_protection) and [Enhanced tracking protection](https://support.mozilla.org/en-US/kb/enhanced-tracking-protection-firefox-desktop)). Firefox also gives third-party cookies a separate cookie jar per site, so they can't be used to track users across sites (see [Total Cookie Protection](https://blog.mozilla.org/en/products/firefox/firefox-rolls-out-total-cookie-protection-by-default-to-all-users-worldwide/)). In [Enhanced tracking protection](https://support.mozilla.org/en-US/kb/enhanced-tracking-protection-firefox-desktop) Strict mode, Firefox now blocks all third-party cookies. Website developers may continue to use third-party cookies with a separate cookie jar per site (partitioned cookies) via [Cookies Having Independent Partitioned State (CHIPS)](/en-US/docs/Web/Privacy/Privacy_sandbox/Partitioned_cookies).
+- Mozilla's [Anti-tracking policy](https://wiki.mozilla.org/Security/Anti_tracking_policy) has led to Firefox blocking third-party cookies from known trackers by default (see [Firefox tracking protection](/en-US/docs/Web/Privacy/Firefox_tracking_protection) and [Enhanced Tracking Protection](https://support.mozilla.org/en-US/kb/enhanced-tracking-protection-firefox-desktop)). Enhanced Tracking Protection can be set to Standard, Strict, or Custom. [Standard mode](https://support.mozilla.org/en-US/kb/enhanced-tracking-protection-firefox-desktop#w_standard-enhanced-tracking-protection) enables [Total Cookie Protection](https://blog.mozilla.org/en/products/firefox/firefox-rolls-out-total-cookie-protection-by-default-to-all-users-worldwide/), which gives third-party cookies a separate cookie jar per site, thereby preventing cross-site tracking. In [Strict mode](https://support.mozilla.org/en-US/kb/enhanced-tracking-protection-firefox-desktop#w_strict-enhanced-tracking-protection), Firefox blocks all third-party cookies.
 - Apple also has a similar [Tracking prevention policy](https://webkit.org/tracking-prevention-policy/); following this has led to a similar set of third-party cookie protections that are enabled by default; see [Intelligent Tracking Prevention](https://webkit.org/tracking-prevention/#intelligent-tracking-prevention-itp) (ITP) for details.
 - At the time of writing, Google Chrome only blocks third-party cookies in Incognito mode by default, although users can set it to block third-party cookies all the time if they wish via `chrome://settings`. Google has started to disable third-party cookies for a limited percentage of Chrome users to test the impact that will have, while at the same time developing technologies to enable key use cases without requiring third-party cookies. See [Replacing third-party cookies](#replacing_third-party_cookies) for details.
 - Edge blocks trackers from unvisited sites, and blocks known harmful trackers by default. At the time of writing Microsoft are also starting to explore blocking third-party cookies in Edge by default. See [Tracking prevention](https://learn.microsoft.com/en-us/microsoft-edge/web-platform/tracking-prevention) for more information.
