I've been using Debian for the longest time because it is one of my favorite distros. I'm taking a Linux course in college this term, and we will be using Fedora 17 for different labs, and to familiarize ourselves with certain things.

I've used Fedora one other time than this, and I solved the issue right away. Now I can't remember what I did and it is driving me crazy.

I installed Fedora on my VM, and Firefox only lets me browse certain sites. This happened the last time I used Fedora, and I went into the Firefox settings, changed one setting, and it worked fine from then on out.

I can't, for the life of me, remember what setting I changed to fix it.

Does anyone have any idea?
