@David ... “I am of the mentality that if it isn’t broke, don’t fix it”. To be frank, I was shocked at the lack of understanding and unwillingness to upgrade.

Firefox' basic public-relations problem is not that a few users will still be running "a very old version of firefox", but rather that all users are being forced to upgrade very recent versions of the software, very frequently.

Users have long tended to harbor suspicions about the motives of software developers, particularly when they are asked to allow the developer greater access to & control of their own computer and the resources installed on it. That is how many perceive the new mandatory update policy of Firefox.

Scratch the surface of public attitudes toward the Internet, and we find concerns about its potential to serve as a tool of 'Big Brother'. We are bombarded by news of sleezy and underhanded maneuvers on the part of such recognizeable developers as Google and Facebook, to, if I may be forgiven the crudity, "screw" the user.

There is a significant, on-going loss of credibility with the public, for developers who claim that they need more control over end-users.
