I've programmed, and worked on various things.

It irritates me to no end when an interface is changed, with no way to revert if you wanted to. Its like having someone order for you at a restaurant, while you sit there fuming at the choices.

Firefox has been nagging me to "upgrade", which I never do until I see the responses. Seeing the firestorm over add-ons getting nuked AGAIN, I'm not upgrading.

I use a variety of them, one that I really like changes the colors of websites so I don't blind myself when navigating sites late at night. (Who thought mimicing paper with black text on white backgrounds made sense anyway - its a skeumorphism that is ridiculous.)

I just refuse to be on that treadmill.

And the thing that is most irritating - they COULD give you a way to revert back to what you want it to look like, but they just didn't.

They can take a running leap off the nearest cliff, as far as I'm concerned.
