AVG pops up stating that is quarantined C://programfiles/MozillaFirefox.exe

Firefox saves downloads to the Windows TEMP folder first, then moves them to your selected download destination. It sounds as though AVG is scanning the download in between those two steps and removing the file because it's dangerous or at least suspicious.

Can you double-check that the source of the download is trustworthy? If you aren't using the publisher's official site, you might check that instead.
