When the target world of a scriptlet is the ISOLATED one,
skip Blob-based injection in Firefox, as the current world
is always the ISOLATED one. This should make ISOLATED
world-based scriptlets more reliable (i.e. execute sooner)
in Firefox.
The `urltransform` option allows to redirect a non-blocked network
request to another URL. There are restrictions on its usage:
- require a trusted source -- thus uBO-maintained lists or user
filters
- the `urltransform` value must start with a `/`
If at least one of these conditions is not fulfilled, the filter
will be invalid and rejected.
The requirement to start with `/` is to enforce that only the path
part of a URL can be modified, thus ensuring the network request
is redirected to the same scheme and authority (as defined at
https://en.wikipedia.org/wiki/Uniform_Resource_Identifier#Syntax).
Usage example (redirect requests for CSS resources to a non-existing
resource, for demonstration purpose):
||iana.org^$css,urltransform=/notfound.css
Name of this option is inspired from DNR API:
https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/API/declarativeNetRequest/URLTransform
This commit required to bring the concept of "trusted source" to
the static network filtering engine.
As per discussion with uBO volunteers.
Volunteers offering support for uBO will be able to craft links with
specially formed URLs, which once clicked will cause uBO to automatically
force an update of specified filter lists.
The URL must be crafted as shown in the example below:
https://ublockorigin.github.io/uAssets/update-lists.html?listkeys=ublock-filters,easylist
Where the `listkeys` parameter is a comma-separated list of tokens
corresponding to filter lists. If a token does not match an enabled
filter list, it will be ignored.
The ability to update filter lists through a specially crafted link
is available only on uBO's own support sites:
- https://github.com/uBlockOrigin/
- https://reddit.com/r/uBlockOrigin/
- https://ublockorigin.github.io/
Additionally, a visual cue has been added in the "Filter lists" pane
to easily spot the filter lists which have been recently updated, where
"recently" is currently defined as less than an hour ago.
Additionally, finalize versioning scheme for uBOL. Since most updates
will be simply related to update rulesets, the version will from now
on reflects the date at which the extension package was created:
year.month.day.minutes
So for example:
2023.8.19.690
Related issue:

The `randomize` paramater introduced in https://github.com/gorhill/uBlock/commit/418087de9c
is now named `directive`, and beside the `true` value which is meant
to respond with a random 10-character string, it can now take the
following value:
war:[web_accessible_resource name]
In order to mock the XHR response with a web accessible resource. For
example:
piquark6046.github.io##+js(no-xhr-if, adsbygoogle.js, war:googlesyndication_adsbygoogle.js)
Will cause the XHR performed by the webpage to resolve to the content
of `/web_accessible_resources/googlesyndication_adsbygoogle.js`.
Should the resource not exist, the empty string will be returned.
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.
Since in uBOL filter lists from various sources are combined into
a single list, there must be a way to turn on/off trust level
inside the resulting combined filter list so as to be able to
validate the trust level of filters requiring trust.
This commit adds new parser directives understood only by MV3
compiler to turn on/off trust flag internally.
