Sorry, just came back.

After sleeping, it was easier to cope with. :)

I disabled all of my Firefox add-ons and every page here works fine.  After adding them back, one at a time, it's apparent that Ad-Block is no longer compatible.  When it's enabled, I have all of these issues, and when it's disabled, the site runs as expected.  Strange, because I've never had this issue here before, but I'm going to assume either an update here or an update to Ad-Block has caused some sort of incompatibility.

No problem.  I'll just have to remember to disable it when I want to browse Renderosity.
