Well, I hope that someone else finds this thread and benefits from my mistake and doesn't just repeat it in a new guise. Problem was that I had somehow changed the image display settings on that particular machine--to only download images from the same server. Those images are coming from a different server within wikipedia.
Apart from making the silly mistake, I plead being misled by the display of the ALT text. I had leapt to the the conclusion that the equation I was seeing was not being rendered--but if leaping to conclusions was an Olympic sport, I'd have a chest full of gold medals. The status of this bug should be changed to something like "user failed to check his Firefox settings". -- Firefox equation rendering problem in Ubuntu Dapper Drake https://launchpad.net/bugs/51807 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
