We would like to know if Firefox 4 is declared End of Life. We are working on one of our customer's website for which we need to test it on Firefox 4. If we know Firefox 4 is EOL, we will directly test on Firefox 5.

Firefox 4 has been replaced by Firefox 5. There is no support for Firefox 4. The security update for Firefox 4.0.1 is Firefox 5.
