I just DLed portable apps and firfox. I loaded them to my jump drive and started using it, but firefox seems to run slow. What might be causing this? I am used to firefox being so speedu, but it seems like it doesn't load very fast and when it does start loading i can't click anything else in mozilla. Kin do flike it is processing. Is this a portable apps problem or just running it from a jump drive causes it to be slow ?
