It's clear you enjoy a good conspiracy theory, but you are quite wrong. First of all Firefox, in regular mode, already blocks all tracking cookies. There is ZERO extra blocking in privacy mode. > So there's absolutely no real technical reason whatsoever for them to disable it. The only difference is in privacy mode some offline data storage API's do not work (return null, rather than storing, and then discarding, data). T-Mobile uses those API's, and they did not feel like dealing with the case of them not working. If you install an extension that re-enables the API's, magically T-Mobile starts working even in privacy mode! > My guess is that the bug being that Firefox's Privacy Mode actually prevented a lot of T-Mobile's invasive tracking. Like I said, you clearly enjoy conspiracy theories, but T-Mobile doesn't have much tracking on their login page.

> There is ZERO extra blocking in privacy mode. Indeed? But there is extra privacy in privacy mode. I don't have to remember to log-out, I don't have to worry about cached items, I don't have to worry about a tab in Private Mode talking to a tab outside of Private Mode (and indeed, that is extra blocking). > The only difference is in privacy mode some offline data storage API's do not work That's a good thing. I do not want websites to store data on my machine. If the website cannot function without data stored locally then the website is not a valid website. It's now an app. I do not want to install apps in my browser. And further: why is this a technical decision made by their privacy team instead of their engineers? Why don't they able to explicitly state what features are required instead of blanket banning the mode? T-Mobile is clearly in the wrong here.

Plus, why would T-Mobile do "invasive tracking" on their login page? One or two clicks later they'll know exactly who you are.

  Well that's a good point. But then: why is it the privacy policy department who mandated the change?
