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.
`uDom` is old and crusty and `dom` is meant as replacement. The
goal of `dom` is to be simpler and mainly just convenience
methods for handling the DOM with vanilla JS -- this is not a
framework.
Additionally, removed keyboard shortcuts pane which was useful
only on very old versions of Firefox.
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.
