Firefox 4.0 will not install. I have Mac OSX 10.4.11. Error message 10661.
I tried to install Firefox 4.0 and I got an error message 10661 and it said my system would not support it. I have Mac laptop with MAC OSX 10.4.11. Why won't it install using this operating system?

For Mac OS X 10.4.11 or Mac OS X 10.5.8 you can look at:
Firefox 3.6.x can be found here:
