    Mitigate potentially delayed execution of scriptlets in Firefox Related issue: https://github.com/uBlockOrigin/uBlock-issues/issues/3452 Use blob-based injection only when direct injection fails because of a page's CSP. This is a mitigation until a better approach is devised. Such future better approach to investigate: - Use `MAIN` world injection supported by contentScript.register() since Firefox 128 - Investigate registering script to inject ahead of time thru some heuristic

    Improve `prevent-setTimeout`/`prevent-setInterval` scriptlet Add support for range for the `delay` paramater: --- @param [delay] A value to match against the delay. Can be a single value for exact match, or a range: - `min-max`: matches if delay >= min and delay <= max - `min-`: matches if delay >= min - `-max`: matches if delay <= max No delay means to match any delay value. Prepend with `!` to reverse the match condition. --- As discussed with filter list maintainers.

    Improve `trusted-replace-argument` scriptlet As discussed with filter list maintainers, added ability to partially replace an argument using the `repl:` prefix. Updated documentation: --- @scriptlet trusted-replace-argument.js @description Replace an argument passed to a method. Requires a trusted source. @param propChain The property chain to the function which argument must be replaced when called. @param argposRaw The zero-based position of the argument in the argument list. Use a negative number for a position relative to the last argument. @param argraw The replacement value, validated using the same heuristic as with the `set-constant.js` scriptlet. If the replacement value matches `json:...`, the value will be the json-parsed string after `json:`. If the replacement value matches `repl:/.../.../`, the target argument will be replaced according the regex-replacement directive following `repl:` @param [, condition, pattern] Optional. The replacement will occur only when pattern matches the target argument. --- Aditionally, more scriptlets moved into their own files.

    [mv3] Add ability for admins to disable features New managed setting: "disabledFeatures": { "title": "User interface features to disable", "description": "A list of tokens, each of which correspond to a user interface feature to disable.", "type": "array", "items": { "type": "string" } } Supported tokens: - `dashboard`: Prevent access to all dashboard settings - `filteringMode`: Prevent changes to the default filtering mode, or the current filtering mode of any site Related feedback: https://github.com/uBlockOrigin/uBOL-home/discussions/35#discussioncomment-11326086

    [mv3] Do not collect matched rules by default when side-loaded Collecting matched rules when the extension is side-loaded is now opt-in, by enabling "Developer mode" in the dashboard. The reason is to allow the extension to behave same as the official released version when side-loaded. Specifically, as side-loaded extension, uBOL's service worker would wake up due to matched-rule listener even though it would not wake up the worker with same configuration in stable release.

    [mv3] Fix flaw breaking scriptlets injection in optimal/basic mode Not all matching scriptlets were injected on a given site in Optimal or Complete mode when default mode was set to Basic or less. A high profile manifestation of this bug was that Youtube ads were not being blocked when using Optimal on Youtube while default mode was Basic.
