I have been using Firefox 32 bit for about 1 yr. I heard that Mozilla is offering a 64 bit for Windows and I downloaded it this morning. The download was installed in the programs (86) folder. I thought that folder was only for 32 bit programs. How can I tell if I am running 64 bit Firefox? - Tks

Windows 10, Desktop, HP

The WOW64 in your useragent shows it is a 32-bit appication running on 64-bit Windows 7. If you had 64-bit Firefox on 64-bit it would show Win64 in useragent.

Windows users downloading from www.mozilla.org will get 32-bit Firefox so if you want Win64 Firefox go to the Systems &Languages link which is www.mozilla.org/firefox/all/

As for your Flash issue you should start a new thread of your own for this.
