Comment 2 for bug 68158

Agreed with Travis Watkins... There is no trivial way of backporting Firefox 2.0 without affecting all the programs that use the Gecko rendering engine, not to mention not all users would welcome FF 2.0 at this point due to extension compatibility.

Also, Firefox's official binaries are quite simple to unpack into a home directory and create a launcher.... It doesn't take much effort at all to set up your own Firefox 2.0.
