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

New policy setting: `rulesets`
Type: array
Type of array items: string
Each item in the list is a list id (as seen in `rulesets/ruleset-details.json`),
prefixed with either `+` to enable the ruleset, or `-` to disable the ruleset.
Users will not be able to enable or disable rulesets present in the `rulesets`
policy. Disabled rulesets will not appear in the dashboard.
Use `-*` to remove all non-default rulesets, except for those added
using `+[ruleset_id]`.
Additionally, some work has been done to properly handle policy changes in
a non-blocking and deferred manner, as I observed that it often takes long
for calls to `storage.manage.get` to resolve. This potentailly takes care
of the following issue:
https://github.com/uBlockOrigin/uBOL-home/issues/174
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.
Consequently, AdGuard URL Tracking Protection (AUTP) has been
added to the set of available filter lists.
However, removeparam= equivalent DNR rules can only be enforced
when granting uBOL broad permissions. If broad permissions are
not granted, removeparam= equivalent DNR rules are ignored.
Exception removeparam= filters are not supported, and these are
present in AUTP and meant to unbreak some websites which are
known to break as a result of removing query parameters.
This is issue might be mitigated in the future by making the
conversion from filters to DNR rules more complicated but this
can never replace the accuracy of uBO's filtering engine being
able to fully enforce arbitrary exception removeparam= filters.
Also, it is not possible to translate regex-based removeparam=
values to DNR rules, so these are dropped at conversion time.
As with other filters to DNR rules conversion, the converter
coallesce many distinct removeparam= filters into fewer DNR
rules.
First iteration of adding scriptlet support. As with cosmetic
filtering, scriptlet niijection occurs only on sites for which
uBO Lite was granted extended permissions.
At the moment, only three scriptlets are supported:
- abort-current-script
- json-prune
- set-constant
More will be added in the future.
Specific plain CSS cosmetic filters are now supported.
Cosmetic filtering will occur only after the user explicitly
grant uBO extended permissions for a given site, so that it
can inject CSS on the site.
A new button in the popup panel allows a user to grant/revoke
extended permissions to/from uBO Lite for the current site.
More capabilities will be carefully added for when extended
permissions are granted on a site, so specific cosmetic
filtering through plain CSS is the first implemented capability.
Generic and procedural cosmetic filtering is not implemented.
The current implementation for plain CSS cosmetic filters is
through declarative content injection, which does not require
the service worker to be alive, the browser takes care to
inject the cosmetic filters.
However declarative CSS injection does not support user
styles, so the injected cosmetic filters are "weak". I consider
this is a browser issue, since user styles are supported by
Chromium, there is just no way in the API to specify user
styles for the injected content.
Also:
- Fixed dark theme issues
- Added Steven Black's hosts file
Keep in mind all this is very experimental and implementation
details in this release may (will) greatly change in the future.
