I have the DuckDuckGo extension as well, and disabling it yielded the same result for me - everything is once again buttery smooth. I'm still confused, though, since I've had the extension for a lot longer than the time this issue has been occurring.

Same, the patch didn't work but disabling DucklDuckGo Privacy Essentials seems to clear up the issue.

Interesting,

While I am a member (and thus don't have ads), disabling my duckduckgo privacy extension for this site worked.

The DuckDuckGo team has excluded warzone.com from its extension, so it should be working fast again even for those with the extension installed.
