I've got a weird issue going on with one computer. I installed the Blubrry powerpress to put an audio player in my blog. It works fine on most computers, but one computer using IE8 it works fine, but using Firefox, the home blog page opens up for a second and turns white. One thing I noticed is that if I remove the enclosure which contains a link to the mp3, the page opens fine (but has no player). It is only happening on that one computer. Also, I don't have a duplicate link to the mp3 in the blog post itself.
I've completely uninstalled and reinstalled firefox. It is also worth noting that a Mozilla Add-ons box opens up and a box with a red x. I'm a little fuzzy on this part because the computer is remote and I haven't seen this happen. I've tried reinstalling the Java, shockwave, and flash plugins, but that hasn't helped.
