How to disable connections to accounts.firefox.com ?

Hello all,

/Every time/ I start FireFox 52 it (tries to) connect to
"accounts.firefox.com". As far as I know I've never created an account, so
there is zero reason for it to even go there.

What setting does FF have (and where) by which I can switch this "lets try
to connect" off (apart from malforming all of those "accounts.firefox.com"
entries in about:config that is - and hoping that that is enough).

Bonus question:
How can I apply this "don't do that!" setting as a default for all future
accounts.

Regards,
Rudy Wieser

You can stop it _succeeding_ by adding a line to your hosts file.
Whether that will speed things up, slow things down, or have no effect,
depends on what Firefox tries to _do_ with the connection.

(You're sure it's not just the check-for-updates, or bookmark [and
other] syncing function, both of which can be turned off fairly easily?
[Well, check for updates can; I've never turned sync on, so don't know
how easy it is to turn off.])

Firefox Account feature can only be disabled in FF v60+.

Apply the settings to the default preference.

JJ, John,

/Every time/ I start FireFox 52 it (tries to) connect to
"accounts.firefox.com".

I'm embarrassed, it turns out to be my own fault. :-|

I've already been redirecting a number of domains FF wants to call back to
to "no place like home", and recently whipped up some /very/ simple code to
accept the (redirected) SSL requests and display the target domain name.

The problem is that, for debugging, I first parsed a static block of data
which I had stored in the program itself. When I than moved the function
over I forgot to disable this testdata. Hence that domain got displayed
every time, even when fully different ones ("location.services.mozilla.com"
and "tiles.services.mozilla.com") where requested.

tl;dr:
"accounts.firefox.com" isn't a new problem. The other two are, but are
old (and have not been able to find a solution for in regard to using FF own
settings either).
