Ad Blocker (preview)​

The built-in ad blocker introduced in 6.6.11 has received a few improvements in this release. It remains in preview testing - you can follow the feedback issue at Native Ad Blocker - Feedback · Issue #4182.

Custom Filter Lists manager

​A new dialog lets you add and remove your own filter list URLs directly from the UI, rather than being limited to the built-in lists. A new button has been added to the blocker preferences to open the manager.

Filter Lists screen improvements​

The existing Filter Lists screen has received major updates:

• Search box to quickly find lists
  
• “Refresh now” button for manual updates
  
• Refresh interval dropdown (4h, 8h, 12h, 24h, 7d, or default)
  
• Per list “last updated / next refresh” information
  
• Source link icon for each list
  

 Less wasteful update logic​

• Each list’s own Expires value is now respected, instead of a fixed 12h interval applied to all lists
  
• Configurable refresh interval
  
• Manual refresh method exposed to the UI
  
• Better error handling when loading the engine cache
  
• Safer input sanitization before data is passed to the engine
  
• Network observers are registered and unregistered based on blocker state
  

Better cosmetic filtering​

• Early check for whether the blocker is enabled
  
• Cosmetic CSS injection now only runs on HTML pages, avoiding breakage on XML or text content
  
• Hard cap on queried DOM elements to prevent runaway processing
  
• Uses CSS rule insertion instead of rebuilding the full style text
  

Stricter extension detection​

Conflicting ad blocker extensions are now identified only by known extension IDs. Pattern matching on extension name and description has been removed, reducing false positives from unrelated extensions.
