correct, among others it checks youporn. For this check it needs send a request to that domain, which may get flagged in certain corporate IT systems.

That would be a pretty crappy check then. After all any webpage could embed that favicon.

Any page could also embed anything else NSFW, such as actual porn videos. The assumption is that these sites are generally NSFW by association.

What would you propose instead?

In Chrome: Settings > Privacy > Content Settings > Tick 'Block third-party cookies and site data' Also set 'Send a "Do Not Track" request with your browsing traffic' And install uBlock Origin, ofc.

How many people browsing the web would know to do this? Would even 0.5% of users know?

I didn't know about either of these things and I consider myself fairly security savvy (for a programmer).

uBlock Origin looks way better than Ghostery, which I was using until now.

What I really want is something like this and it opening containers automatically based on url sets. So going to facebook would go to the facebook set automatically and isolate facebook. But I don't have to manually open the "facebook profile" to do the switch. Same with twitter, amazon, google*, youtube, apple, etc. If you have multiple accounts, you can have the interface pop up a "choose your subcontainer" automat…

After Firefox adds this, wouldn't that be a relatively simple plug-in? Just maintain a list of known info greedy URLs? (Note, not a tracker blocklist)

Hmm weird, it correctly detected everything except for the false negatives of PayPal, Tumblr, and Spotify. Taking a look at the mechanism I have no idea why this would happen, and opening the relevant links in my browser gives the favicon as it should. Weird.

As somebody who tried to build code respecting "Do Not Track" preferences, I have to say that feature, while well-intended, is a complete farce.

Chrome, Safari, Firefox, IE9, IE10, and IE11 all use different APIs for Do Not Track [1], so a front-end developer has to do a lot of extra leg work to check if the user has the preference set.

I find it highly unlikely that most companies would go through the effort of respecting Do Not Track.

This only works of you have third party cookies turned on. I'm not sure about Opera, but I'm pretty sure Firefox has them off by default.

Firefox has third party cookies enabled by default, PLUS they hide the setting so you have to search for it to disable it. I'm 100% sure that they designed it that way to please Google. The pull requests to change it were ignored. And then they claim to be your partner in keeping your privacy. AFAIK only Safari has 3rd party cookies disabled by default. There are only very few sites that require 3rd party cookies. I…

Sorry I was wrong about Firefox, I must have reconfigured mine and forgotten about it. My point was that Privacy Badger alone won't prevent this attack, you have to disable 3rd party cookies.

This is why I use 'browser isolation', which is a way to separate different types of surfing activity into different buckets. Currently the best way to do this in Firefox is to create multiple profiles, or in Chrome, you can simply add a different user/persona. Having one profile, or even an entire dedicated browser just for Twitter/FB ensures the login is not spilled over into other sites. If you're surfing the web…

Its only in testing right now, but Firefox Nightly has "Containers" so you can exactly have different "buckets" for different types of browsing - https://wiki.mozilla.org/Security/Contextual_Identity_Projec...

Yes! I use and love containers.

If a filter is set up to not just block access to but also flag based on something as trivial to embed as a URL one would hope the technology would be a little bit more involved than a single hit on a .ico file for a flag.
