If you're having an issue with the comments not loading, the problem has a pretty simple solution. Turn off AdBlock.
Of course, you probably don't really want to do that, so the more complicated solution is to open your blockable items via the AdBlock menu. In the list, there will be an item with the following address:
That script was added to AdBlock's filters the other day, and unfortunately blocking that script prevents the page from loading both comments and main article images. Right-click on that item and select "Disable filter" and reload, and you should be all set.
UPDATE: AdBlock has themselves removed the script in question from their filters, so if you go into Filter Preferences, click Actions, and Update Filters, it will solve the problem.
