I Tried Mozilla Firefox three and did not care for it as it is Still needing Upgrades! So, I went back to Mozilla Firefox 2.0, because it is Stable and is just as Fast as three!
Firefox three Still don't have all the plug ins for certain projects yet. You can Still Use Firefox 2.0 and all its wonderful Plug ins and it works Great! I think Firefox Three will be good in the near future when they are done upgrading it!
