Add information about which ruleset caused a page to be strict-
blocked.
Whenever possible, add ability to URL-skip an incoming redirect
in a strict-blocked page.
Add new default list: "30-day Phishing Domain List"

This implements basic functionality for strict blocking, i.e. the
ability to block navigation to undesirable websites. This is a
first implementation, which converts only filters that are plain
hostnames.
Unlike with uBO, it is not possible to know from which ruleset a
blocking rule originates. Nonetheless, users will have to make a
choice as to whether navigation should proceed or not.
A setting has been added to the dashboard to wholly enable/disable
strict blocking. It is enabled by default.
Potential future improvements, pending investigation on feasability
in an MV3 framework:
- Extend coverage to explicit `document` filters
- Leverage and use `urlskip=` filters in the blocking page in order
to proceed while bypassing unwanted redirects.
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.

Add "Filter lists" pane in dashboard
The DNR API now supports enabling 50 static rulesets put of a
maximum of 100 (instead of 10 out of 50 originally). Thus given
the potentially growing number of static rulesets, the available
stock rulesets has been moved to its own pane, with the following
improvements:
- Support sublists
- Support search
Aditionally, "RU AdList: Counter" has been added as a stock
ruleset.
Other changes:
- Do not re-evaluate regexes which failed validation
- Better reduce `removeparam` rules
@trustedScriptlet trusted-set-attr
@description
Sets the specified attribute on the specified elements. This scriptlet runs
once when the page loads then afterward on DOM mutations.
Reference: https://github.com/AdguardTeam/Scriptlets/blob/master/wiki/about-trusted-scriptlets.md#-%EF%B8%8F-trusted-set-attr
@param selector
A CSS selector for the elements to target.
@param attr
The name of the attribute to modify.
@param value
The new value of the attribute. Since the scriptlet requires a trusted
source, the value can be anything.
=====
Additionally, start to move scriptlets into their own source files
for easier maintenance and code review.
A new icon has been added to the popup panel, to open a popup
window with a terse list of DNR events for the current tab, in
reverse chronological order (most recent DNR event appears at
the top).
The new ability is available only when the extension is sideloaded,
as per `declarativeNetRequestFeedback` documentation. Ref:
https://developer.chrome.com/docs/extensions/reference/api/declarativeNetRequest#event-onRuleMatchedDebug
Purposefully minimal, so as to have something rather than nothing
when having to diagnose filtering issue with the DNR API. Example:
https://github.com/uBlockOrigin/uBOL-home/issues/156
The content of the popup window does not dynamically update, force
a refresh (F5) to get the most recent DNR events. This might be
improved in the future.
The DNR event buffer is not persisted, so the buffer is empty when
service worker is restarted. This might be improved in the future
by using session storage API.
There is no output filtering ability in this first draft. This
might be improved in the future.
DNR rules are reported. The filter from which a DNR rule
originates is not reported. Given that the rulesets are optimized
after conversion from original filter lists to reduce the DNR rule
count, this is unlikely to ever be possible.
This is to reduce the diff size of rulesets in new
releases. Beside smaller diff size, this also makes it
easier to investigate rule changes across releases.
Additionally:
Use `export UBO_VERSION=local` at the console to build MV3 extension using
current version of uBO code base. By default, the version is taken from
`./platform/mv3/ubo-version' and usually set to last stable release.
See `managed_storage.json` for available settings. Currently
only `noFiltering` setting is availale.
`noFiltering` is an array of strings, each being a domain for
which no filtering should occur.

Source code of scriplets is now fetched directly from uBO
project, so there is no longer the need to keep duplicate
versions of scriplet code.
All scriplet filters are now supported.
What does not work at the time of commit:
Cosmetic filtering does not work:
The content scripts responsible for cosmetic filtering fail when
trying to inject the stylesheets through document.adoptedStyleSheets,
with the following error message:
XrayWrapper denied access to property Symbol.iterator
(reason: object is not safely Xrayable).
See https://developer.mozilla.org/en-US/docs/Xray_vision for more
information. ... css-declarative.js:106:8
A possible solution is to inject those content scripts in the
MAIN world. However Firefox scripting API does not support MAIN
world injection at the moment.
Scriptlet-filtering does not work:
Because scriptlet code needs to be injected in the MAIN world,
and this is currently not supported by Firefox's scripting API,
see https://bugzilla.mozilla.org/show_bug.cgi?id=1736575
There is no count badge on the toolbar icon in Firefox, as it
currently does not support the `DNR.setExtensionActionOptions`
method.
Other than the above issues, it does appear uBO is blocking
properly with no error reported in the dev console.
The adoptedStyleSheets issue though is worrisome, as the
cosmetic filtering content scripts were designed with ISOLATED
world injection in mind. Being forced to inject in MAIN world
(when available) make things a bit more complicated as uBO
has to ensure it's global variables do not leak into the page.
