Is the adblocker feature enabled?

Is the adblocker fully ready? In case the adblocker is enabled but not yet ready, it could mean that the initialization is still on-going.

Most adblockers require you to manually hand-pick the lists you want to load to fine-tune your experience. Instead, Cliqz will locally analyze the languages of the websites you visit and automatically load country-specific rules to optimize the experience (e.g.: if you visit German websites, easylist-germany will be automatically enabled for you).

This is the full list of all supported regions for the adblocker; they are not enabled by default. This list has been currated to make sure it does not introduce too many breakages for our users. These can be enabled either automatically by the mechanism described above, or manually using the overriding pref cliqz-adb-lang.

Different devices have different characteristics. To make sure you get the best experience, Cliqz will fine-tune the adblocker depending on the platform.

Available lists are specified in a JSON file hosted on Cliqz' CDN. The adblocker is using this information to know which rules to load and check if updates are available. Additionally, pre-initialized blocking engines are created on the backend and can be fetched by clients to remove the need for heavy-lifting.

The adblocker will automatically check for updates every hour. This indicates the last time an update happened.

The engine is the master-mind of the adblocker, it contains all the rules from enabled lists and is in charge of deciding what to do to block ads. To allow fast cold-starts, it can be serialized to a very compact representation which is persisted on disk and loaded when the browser starts. It can also be shipped directly from the CDN.

To maximize performance, the adblocker is able to perform dynamic optimizations on its internal rules. For examples, similar rules can be fused into one. Due to platform-specific limitations, this option can be disabled.

This option indicates if the adblocker was initialized in debug mode. This means that extra information is kept at runtime to ease debugging. In particular, it is possible to retrieve the original text form of each rule. This should always be false in production.

Indicates if network filtering rules are currently enabled, this should always be true.

Indicates if cosmetic filtering rules are currently enabled, this should always be true.

Indicates if generic cosmetic filtering rules are currently enabled. Generic cosmetic rules do not specify a specific domain on which they should be applied, but instead are used on any website. This should usually be true but could be disabled on some platforms (e.g.: some mobile configs).
