uBlock Origin 1.22.0

New

Toolbar icon badge color

The toolbar icon badge color will now reflect the current blocking mode. This should help with usage of the

"Relax blocking mode" shortcut. The way uBO relaxes the current blocking mode is configurable through the

advanced setting blockingProfiles.

Static network filter options

redirect-rule=

This new option allows to create a pure redirect directive, without a corresponding block filter as would be the case with the

redirect= option. For example, consider the following filter:

||example.com/ads.js$script,redirect=noop.js

The above filter will result in a block filter ||example.com/ads.js$script and a matching redirect directive.

Now consider this following filter:

||example.com/ads.js$script,redirect-rule=noop.js

The above filter will not cause a block filter to be created, only a redirect directive will be created. Standalone

redirect directives are useful when the blocking of a resource is optional but we still want the resource to be

redirected should it ever be blocked by whatever mean -- whether through a separate block filter, a dynamic

filtering rule, etc.

empty and mp4

Support for AdGuard's empty and mp4 filter option has been added.

!#if false ... !#endif

Support for the directive !#if false to easily disable a block of filters, which is more convenient than having

to delete them all or prefix them all with !.

Scriptlet injection

Ability to wholly disable scriptlet injection for a given site using broad scriptlet injection exception:

example.com#@#+js()

It is also possible to disable scriptlet injection everywhere with a generic exception:

#@#+js()

This is useful when creating specific exception filters is inconvenient.
