New

New cosmetic procedural operator: :nth-ancestor(x), where x is the distance from the currently selected node. It is effectively a low-overhead equivalent to :xpath(..[/..]*). Using an existing filter as an example:

fastbay.org##.detLink:has-text(VPN):xpath(../../..)

Could be rewritten with the new operator:

fastbay.org##.detLink:has-text(VPN):nth-ancestor(3)

The new operator has a lower overhead as it avoids the need to create and execute XPath expressions.

Closed as fixed

Chromium

• web_accessible_resource secret token accessible to webpages
  • Related Chromium issue: https://bugs.chromium.org/p/chromium/issues/detail?id=957866.
  • This currently affects browsers based on Chromium 74. I was unable to reproduce the issue with Chromium 73 or Google Chrome 75.
  • The mitigation here is to create a new secret token for every network request which is internally redirected to a web accessible resource.
• DNS Prefetching on HTTP sites

Firefox

• Firefox does not load homepage completely when operating in Single-process

Core

• No Large Media setting with 0KB should block all images
• Incorrect display of hostnames with numbers in the logger
• Remove duplicate lines when importing user filters
• Can't add some network filters via element picker, create button grayed out
• Wrong Map method used (pull request by n-leigh)
• Make the lists activate by default in browser languages that are minority languages in the lists' countries
• Dashboard tabs are unresponsive after a while
• ::before / ::after no longer hidden as generic filter?
