If an IP address can be extracted from the hostname portion of
a URL, the IP address matching will be performed at onBeforeRequest()
time.
Regardless, IP address matching will subsequently always be performed
at onHeadersReceived() time as the request details at that point
contain a reliable IP address value on supported platforms (Firefox-
only as of now).
The `cap_ipaddress` now evaluates to `true` in Chromium-based
browsers. Even though these browsers are unable to provide reliable
IP address value at onHeadersReceived() time, they can still
perform IP address matching for IP address extracted from hostname
portion of a URL.
Properly report unsupported `header=` and `ipaddress=` option in
log file.
`header=` support may become possible soon with Chromium 128
introducing blocking according to response headers content.
The purpose is to block according to the ip address of a network
request. In the current implementation, the filter option can only
be enforced at onHeadersReceived time.
The new filter option cannot be enforced in Chromium-based browsers
since the ip address of network requests is available only at
onResponseStarted time, which is not blocking.
The value assigned to `ipaddress` can either be a plain string which
must match exactly a given ip address, or a regex which will be
matched against the ip address.
The `ipaddress` option can only be enforced when the extension
framework does provide a valid ip address in a onHeadersReceived
listener. For instance, cached resources do not have a valid ip
address and thus can't be a match to `ipaddress` option.
Example:
*$script,ipaddress=93.184.215.14
For the sake of convenience for filter list maintainers, this commit
add ability to quote static network option values, so as to avoid the
need to escape commas when parser ambiguity arises.
The quotes can be `"`, `'`, or backticks.
Example, the following filter requires escaping commas:
example.com$xhr,replace=/"loremIpsum.*?([A-Z]"\}|"\}{2\,4})\}\]\,//,1p
Can be now rewritten with no need to escape when using quotes:
example.com$xhr,replace='/"loremIpsum.*?([A-Z]"\}|"\}{2,4})\}\],//',1p
* Maintenance for the Serbo-Croatian Filters section
* Implemented the request to move to contentURLs
I sure I hope I understood the request correctly, or things would get slightly awkward for me.

There used to be a way to test URL against the network filtering engine,
but this was removed in a distant past during refactoring.
The ability has been brought back through uBO's own developer tools,
accessible through the _More_ button in the _Support_ pane in the
dashboard.
To query the static network filtering engine, enter the following
in the text editor:
snfe?url-to-test [type] [url-of-context]
`snfe?` is a prompt indicating the intent to query the static network
filtering engine.
At a minimum there must be a URL to test.
Optionally the type of the resource to match, default to `xhr` if
none specified. Also optionally, the context from within which the
request is made. Example:
Enter:
snfe?https://www.google-analytics.com/analytics.js
Result:
url: https://www.google-analytics.com/analytics.js
blocked: ||google-analytics.com^
Enter:
snfe?https://www.google-analytics.com/analytics.js script
Result:
url: https://www.google-analytics.com/analytics.js
type: script
blocked: ||google-analytics.com^
modified: ||google-analytics.com/analytics.js$script,redirect-rule=google-analytics_analytics.js:5
Enter:
snfe?https://example.com/
Result:
url: https://example.com/
not blocked
Enter:
snfe?https://example.com/ ping
Result:
url: https://example.com/
type: ping
blocked: *$ping,3p
