That annoying "TRUSTe" modal. The one you see on java.com for example?

While I have seen less of the "30 seconds to save" issue recently (I dunno if it was a ublock origin update or the ad companies actually fix their scripts). The issue causing it was ublock origin. Looking at the network activity when it was happening (it pissed me off too), the script was sending a request to each of the partners with your prefence and the script had to wait for the timeout on the request (as ublock was blocking the request) before moving onto the next batch. this scaled over all the partners listed in their ad/tracking partners added up for a piss take of a long time.

But as I said for me personally when I see that particular opt in/out modal these days it saves almost instantly, so someone somewhere fixed it :-)

EDIT: thinking about it, it might of even been the addition of FireFox's built in tracker protection that "fixed" the issue for me. I can't recall extactly when I stopped seeing the TRUSTe modal take forever to save my prefs.

I don't know if uBlock Origin increases this further, but even without it it's ridiculous. We measured this just for fun in a paper last year [1]:

> Compared to accepting cookies, opting out causes an additional 279 HTTP(S) requests to 25 domains, which amounts to an additional 1.2 MB / 5.8 MB of data transfer (compressed / uncompressed).

Its been an age since I looked into it. But I remember if you disabled uBlock on the page before you hit save, it updated the settings a lot faster then if it was enabled. Same thing for the Ad Choice mass optout tool (Though that would say it failed to opt out for all the companies as it couldn't send the request).
