The new Content Blocking section in the site identity panel has an item called "Slow-loading Trackers". If I click the gear icon to configure my Content Blocking settings, it's instead called Slow Tracking Elements. 1. Those two names should probably be the same 2. Slow-loading Trackers should be a subset of Trackers The description in preferences explains this is actually about blocking third-party content that loads slowly, but at least in my understanding that's different from trackers. It might be worth quickly making the distinction between generic third-party content and tracking content (AFAICT, tracking content is third-party content whose domain is on Disconnect's list) right there in the preferences section, since the options otherwise don't make much sense.

The new description is hopefully more clear, this setting is about blocking trackers after a threshold past the navigation start time. This isn't really a subset of Trackers, since the same set of trackers is used to drive both features. > It might be worth quickly making the distinction between generic third-party > content and tracking content (AFAICT, tracking content is third-party > content whose domain is on Disconnect's list) right there in the preferences > section, since the options otherwise don't make much sense. We already have such documentation in our support page that is linked to from the Learn More link in the UI: https://support.mozilla.org/en-US/kb/tracking-protection?as=u&utm_source=inproduct Since this bug is talking mostly about updating the UI strings used in the Content Blocking section of preferences, duping against bug 1480900.
