The latest version of Firefox is fully compatible with the Windows 7 operating system.

Mozilla has one version of Firefox for Windows XP through Windows 10, which is the standard "32-bit" version that runs on 32-bit and 64-bit Windows. That's the one you posted from.

There is also a 64-bit version, but it only supports two plugins, Flash and Silverlight, so if you use Java, Google Talk, or other plugins, that's not a good choice for you.

Do you need a fresh download of Firefox??

The Win64 Firefox needs 64-bit Windows 7, 8 (8.1) , 10.

The 32-bit Firefox runs on 32-bit/64-bit Windows XP SP2+SP3, Vista, Windows servers, Windows 7, 8 (8.1) , 10.

James gives the link. Scroll down to your preferred language on that page.

Note that only the Shockwave Flash plugin and Silverlight plugins are enabled for 64 bit Firefox versions for Windows. If you need to use other plugins like Java or media players then install the 32 bit Firefox release.
