How is that related to Firefox support?

Firefox is a 32-bit browser for Windows and needs 32-bit plugins.

If this is about Java for Internet Explorer, see Java support or an IE support forum for help.

How is it related to support? Support is when a question is being asked about a product. If firefox is a 32 bit browser, why are we directed to the site when we enter "firefox 64 bit browser" to a search engine, and the site does not state what version it is, contrary to other browser sites

Sorry, but I didn't see Firefox anywhere in your original posting, and still don't even after you edited your original statement.

1. Mozilla doesn't have a 64-bit release version for Windows OS's.
2. Firefox for Mac is a dual 32 / 64 bit DMZ package - you get both in one package.
3. For Linux you'll get 64-bit if the UA of the browser you are using is a 64 bit version of the browser being used. Plus there's an option to select the 32-bit version for download.

BTW, there's no 160 character limit to postings here, and question marks help us older folk know a question from a statement.
