To protect you from most ads and trackers, Orion for Mac includes the following blocklists by default:
- EasyList (Enabled)
- EasyPrivacy (Enabled)
- Fanboy's Annoyance (Disabled)
You can enable or disable these blocklists in Orion > Settings > Privacy, then click the Show Filter Lists button.
Orion for Mac allows you to customize it's ad blocker by using custom blocklists. Blocklists are lists of domains that are known to serve ads, trackers, malware and other annoyances. Orion checks web page requests against these lists and blocks any requests to the listed domains. This prevents ads from being displayed and trackers from following you around.
Blocklists are constantly updated as new ad/tracking domains appear. List maintainers work to identify and add new ad-serving domains as they pop up.
To manually update blocklists, go to Orion > Settings > Privacy and click Update Now. Wait for the "Processing update" message to disappear.
To add a blocklist to Orion, go to Orion > Settings > Privacy and click the Show Filter Lists button. Please note that Orion is compatible with Adblock Plus style blocklists.
Next, in the modal that opens, click the + button.
Then, paste the URL of the blocklist you wish to add and click the Add button. Finally click Done.
Impact of Number of Blocking Rules on Performance
Orion's content blocker compiles each blocklist to convert it to native WebKit content blocking rules. This results in minimal performance impact dependent on the number of blocking rules that are active. The following chart illustrates the relationship between Orion's WebKit performance vs the number of blocking rules:
There are different types of lists - general ad lists, regional lists, malware lists, privacy lists, etc. You can customize your ad blocking by choosing which lists you want to add to Orion.
The FilterLists website provides a comprehensive directory of blocklists you can add to Orion.

Note: Snippet filters are not supported.
Contributing to Blocklists
Many blocklists are open source and maintained by independent groups and communities. Anyone can submit domains for inclusion in the lists.
