I have FF 3.0 on my desktop but when I move the firefox icon to the applications icon it says I do not have sufficient privileges to complete the action. When I tried to upgrade to 4.0 it said it could not do it. I suspect my OS cannot handle 4.0

Sorry, Firefox 2.0.0.20 is the last ever release for Mac OSX 10.3.9 and earlier versions.

Firefox 4 doesn't run on a PowerPC Mac.

Firefox 4 requires at least OS X 10.5 and an Intel Mac.

Firefox 2.0.0.20 is the last release that runs on Mac OS X 10.2 and 10.3


For Mac OS X 10.4.11 or Mac OS X 10.5.8 you can look at:

Firefox 3.6.x (Mac OS X 10.4 and later) can be found here:

I have 2.0 .I want to upgrade to 3.0 or whatever OS 10.3.9 will handle. When I try to install 3.0 it says I do not have sufficient privileges.

You can't update Firefox to a later version than the 2.0.0.20 that you currently have on Mac OS X 10.3.9. All later Firefox versions require Mac OS X 10.4 or later. The only way to use newer Firefox versions is to update your OS.
