Writing this down here, because although I have synchronization turned on in Firefox, I have a couple of new machines, and the setting isn’t syncing over:
uBlock Origin > Dashboard (it is the gear wheels icons) > My Filters > add the following:
https://accounts.google.com/gsi/*With this in the filters list, Firefox won’t pop up that annoying login box.
I don’t know whether this enhances privacy or not.
Without the filter, the website you are visiting has some content on it which tells your browser that the browser should rat you out to Google fetch this login form from Google.
You should feel uncomfortable when that login prompt box shows up on the porn site you are visiting, by the way. Also if you are a Tea Party member or a Black Lives Matter member.
So, without the filter, your browser is definitely reaching out to a Google server and interacting with it, supplying IP address and whatever else Google asks for. Google is also then supplying this login prompt code to run in your browser.
With the filter, I don’t know.
The website page has code (which will be shipped to your browser) that your browser should request from Google this login form.
I don’t know if the filter strips out the request for the login form, or brings down the login form and immediately returns “no information for accounts.google.com is available”.
If the former, it might protect some privacy. I don’t know if uBlock Origin stops the login form from being loaded from Google. If so, probably Google didn’t get notified that you visited that website.
If the latter, then Google shipped the code to your browser. But before it could ship that code to your browser, your browser had to hand over your IP address as the destination to ship to. And as long as they are preparing the login script code to ship to you, then need a little more information…. (user agent, screen size, is JavaScript enabled, whose’s your daddy, and any other fingerprinting data they can get).
If I were DHS (who is paying Google with your tax dollars to rat you out to DHS), I’d have Google supply the login form code from a different host and domain than accounts.google.com. This filter could still remove all code that points the browser to accounts.google.com, but it is the initial download of the login page pop-up form that lets Google record that you visited website foo at a particular date and time and from where.
