实验阶段过滤规则

所谓实验阶段过滤规则是指那些正在被评估是否可加入 uBlock Origin's 默认规则集的过滤规则。default set of filters. They are being evaluated to assess whether they cause undue web page breakages.

The Experimental filters are disabled by default, enable only if you want to help evaluate/fine tune these filters.

If you find web pages broken by one of these filters, please open a GitHub issue with all the proper details^[1] if and only if you are able to confirm that one of the experimental filter is causing the web page breakage.

There are currently two experimental filters, which are block-then-redirect filters, to block the following resources:

• googletagservices.com/tag/js/gpt.js: Normally not blocked by EasyPrivacy.
• www.google-analytics.com/ga.js: Normally blocked by uBO, but blocking this resource has sometimes led to page breakage, so exception filters have been required. By forcing a redirect to a neutered version, the goal is to reduce page breakage while avoiding the need to create an exception filter for some sites (example).

Note that these two experimental filters use the important filter option, so they will bypass any existing exception filters.
