I just installed Mandriva PowerPack 2007 and everything is running great but Firefox. When I try to open it, a mini Firefox logo is bouncing up and down next to the cursor and the tab on the taskbar appears with a hourglass for a few seconds and then just disappears. I downloaded and installed Firefox 2.0 and it worked for a little while, but now it does the same thing, the browser won't come up. Does anyone know what is wrong? Thank you in advance!
