It is the right way to go. While it means that the users are less in control of the software they run on their computers, it simplifies the development and maintenance by a great deal.
I must be stoned while I'm reading this.
How, in the name of all that is decent, can giving users less control over what gets installed on their machines ever be viewed as "the right way to go"?
FORCING updates is a bad idea.
If Microsoft did this, there would be no end to the ever rising volume and levels of obscenity and profanity, which even I could not hope to aspire to.
If I did this, people would scream at me.
If Adobe did this, people would cry bloody murder.
This already happens in the gaming world, and it's annoying as Hell.
Forcing updates in Firefox, for me, will make it only useful for testing. I would never use it again. After I went to try to use it, and it told me to wait for 5 minutes (or whatever) while it updates? Sorry. I have 3 other browsers open already, and I don't need the hassle.
However, I think it is a good thing for most people. Having it update by default would be good (for most people), but an opt out would be necessary. I would be happy with the option to not update.
