I have everything up to date (Java, Flash, etc) and when there's a pop up or a clickable option on a website (like to equip something to a avatar or something in a pop up window) all I get is a "#" at the end of my URL and it moves me to the very top of the page. The only time that this doesn't happen is when the page is still loading (when the page is still loading, I have full access to the page to do anything normally. Clicking the items to be equipped or clicking the pop up window works). Every time the page is fully loaded, it become unresponsive. I've tried clearing my cache, cookies, and all other personal data except add-ons (which didn't affect it's performance before). I still had this problem. On my Add-ons it says that my Java Console is incomparable with my FF, but this didn't affect the performance of my FF.
