The surest way I've found to re-produce is to try to open the latest review within a day or two of posting. For some reason I'm able to load the later reviews, so I suspect it has something to do with how the site handles high-traffic pages vs normal-trafficDave from DuckDuckGo here. We'd like to fix this for you but we can't reproduce the problem.
Is there any chance you could provide us with some concrete steps to follow in order to trigger the problem? Also, please could you let us know the version of your Operating System, Firefox and the DuckDuckGo extension you've got installed? Finally, please could you confirm if you have any other browser extensions installed, and if so which ones?
Thanks for the help!
