Why Mozilla Firefox Quantum offline installer?

But for some people who would like to mass install Firefox Quantum on multiple standalone computers that may not have internet access, you will need to download the Mozilla Firefox Quantum offline installer for Windows 10 64-bit or 32-bit.

The Firefox Quantum offline installer is also useful when the web installer’s download speed is very slow or simply not working. Because of this, many people don’t like online installer and still prefer to use offline installer for software that they need in their daily life.
