Firefox works for their users
All these older operating system are working so well these days compared to all the modern "updated" versions of things that are busy telling users that they are no longer supported. Goodbye Chrome, and Google Drive ... all upgraded with no longer user support.
I've always been happy to upgrade Windows until the "upgrades" started to result in me spending less time working and more time waiting for updates - what's a update these days? Oh, just new bugs most of the time.
