Then why does my firefox freeze my comp if I have too many tabs open?

  You can have thousands of unloaded tabs, but loaded tabs can gobble up memory and your computer may start swapping. It will usually recover from that but it can take a minute or two. If you get that often, you can open about:processes , sort on memory use and kill a few of the largest processes, which will unload their tabs.
