Hi Unfortunately, I do not think this is going to be possible. Firefox is not available on the Blackberry operating system (that they were using at the time). I notice that the computer that you are using to write to us is using an older version of Firefox. I recommend that you update to make sure that you have the latest security and stability fixes. You can read more about how to do this [https://support.mozilla.org/en-US/kb/update-firefox-latest-version here].
