Your reply changes the definition of "opt-is". He's not saying "Hello is opt-in because you can choose not to use an active feature if you don't want to", he's saying it's not enabled unless you actually use it by clicking on it, otherwise it is an inert feature that isn't doing anything. You have to take actions (opt in) in order for it to be active. If Firefox included an extra theme with the download, but I had to specifically go in and choose that theme, it would be analogous. Ask Toolbar is not analogous, because it is operational as soon it is installed.
Sorry, but mildly put, your definition of opt-in seems to be an unrealistic one. If you think Mozilla should ask whether people want to have a change or not for every single change, then that's your prerogative, it has nothing to do with practical software development though.
"Click INSTALL to install this third party software"
I did not realize that this community had become so adverse to traditional software that asking a user before installing new software was now considered "revising definitions" and weird.
That's all I want: To be asked before third party software is automatically installed.
We used to call that adware/malware when a company bundled third party software without permission.
Are you being serious right now?
Ok, how about this, We auto-install the Ask Toolbar on every single Firefox installation, 100%, everyone gets the Toolbar.
But don't worry!
If you don't click on the Toolbar which automatically installs and appears in your browser, you won't use it!
It's "Opt in"!
The funny part is, can you tell me how to uninstall Firefox Hello completely?
Mozilla's NO SURPRISES policy says I should be able to uninstall unwanted extensions with no loss to my browser.
So, can you help me achieve NO SURPRISES by removing the surprising and unwanted third party Hello feature?
