Fix for New Firefox releases

Fix for New Firefox releases that are provided in tar.xz instead of tar.bz2 #44

Firefox releases from v135 onwards use tar.xz instead of tar.bz2.
Updated the extraction logic to detect the correct archive format based on version and extract it accordingly.

Thanks for your PR @minhaj3!

While you correctly check for the file extension to decompress, still, the URL will also differ depending on this file extension.
Consider for example:

• https://ftp.mozilla.org/pub/firefox/releases/134.0/linux-x86_64/en-US/firefox-134.0.tar.bz2
• https://ftp.mozilla.org/pub/firefox/releases/135.0/linux-x86_64/en-US/firefox-135.0.tar.xz

I will go over the options on how to also take into account the different URL and add it this PR, and eventually merge.

Thanks for checking the PR.
I have been busy with some other work recently. I will also check it as soon as possible.

Would love to get this merged. It will be my very first merged PR.
