uBlock Origin Icon

Light-weight, fast browser extension for Firefox and Chromium (Chrome, Edge, Brave Opera etc), that blocks tracking, ads and known malware. uBlock is easy-to-use out-of-the-box, but also has a highly customisable advanced mode, with a point-and-click firewall which can be configured on a per-site basis.

    Add `trusted-prevent-dom-bypass` scriptlet @description Prevent the bypassing of uBO scriptlets through anonymous embedded context. To ensure that a target method in the embedded context is using the corresponding parent context's method (which is assumed to be properly patched), or to replace the embedded context with that of the parent context. Root issue: https://issues.chromium.org/issues/40202434 @param methodPath The method which calls must be intercepted. The arguments of the intercepted calls are assumed to be HTMLElement, anything else will be ignored. @param selector (optional) A plain CSS selector which will be used in a `document.querySelector()` call, to validate that the returned element must be processed by the scriptlet. If no selector is provided, all elements will be processed. @param targetMethod (optional) The method in the embedded context which should be delegated to the parent context. If no method is specified, the embedded context becomes the parent one, i.e. all properties of the embedded context will be that of the parent context.

    Imrpove `prevent-xhr` scriptlet; add `trusted-prevent-xhr` scriptlet Add support for synchronous `send()` calls. `trusted-prevent-xhr` is essentially the same as `prevent-xhr` except that if the `directive` argument is not a known token, it will be used as is as the response text of the xhr request, whereas `prevent-xhr` returns an empty string when the directive is unknown.

    Skip dns resolution when requests are proxied through http Related issue: https://github.com/uBlockOrigin/uBlock-issues/discussions/3396 Reference: https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/API/proxy/ProxyInfo#type_2

    Blocking large media elements also prevents autoplay, regardless of size Related issue: https://github.com/uBlockOrigin/uBlock-issues/issues/3394 When the "No large media elements" per-site switch is toggled on, it will also act to prevent autoplay of video/audio media, regardless of their size. This also works for xhr-based media streaming. If blocking by size is not desirable while blocking autoplay is desired, one can toggle on "No large media elements" switch while setting "Block media elements larger than ..." to a very high value.
