Fix Disqus comments not loading in Firefox

A couple of years ago, Firefox's Enhanced Tracking Protection prevented Disqus comment sections from loading. At the time, this could be resolved by setting preference urlclassifier.trackingSkipURLs to:

disqus.com, referrer.disqus.com, *.disqus.com, c.disquscdn.com

This stopped working in Firefox version 139. Per Bugzilla, this can be resolved again by adjusting the preference value to the updated format:

*://disqus.com/*,*://*.disqus.com/*,*://referrer.disqus.com/*,*://c.disquscdn.com/*
