During the development of a new version of Firefox, Mozilla divided into many different Build packages, and Build Nightly was one of those Builds, and it was developed by Moziila in two versions: 32-bit and 64- bit. What is Firefox's Nightly Build for 64-bit Windows users? If you are using Firefox on Windows, then the mainstream, stable version, which we usually download from Mozilla's home page is a 32-bit version of Firefox, although Windows you are installing on your computer is a good 32-bit Windows.
As for Linux and Mac OS X, because of the contract, the 64-bit version is still available. They said they would stop developing Firefox's Nightly Build for 64-bit Windows users. Recently, Mozilla - the famous Firefox browser developer - has made a decision to cause a lot of 'discontent' in this browser user community.
