Co-founder here. This took us by surprise, we were planning to have Firefox and Safari support done by launch. At this stage, it is priceless to know if we are solving a real problem people have. Also, is this something people would pay for (loops back to if this is enough of a pain point). From the moment we start charging, is the moment we start learning.

Vinny Glennon, One of the founders here. Thanks very much for the up votes. The Chrome extension does not work in private browsing. I have a set of porn sites(1.7 million stored in redis) that I check if incoming links are a member of. You can selectively block sites ( https://www.seenbefore.com/blacklist_items ).

Do you store the entire set of 1.7 million entries in redis? Or is redis an index to data stored elsewhere, in a relational DB perhaps? I was under the impression that redis wouldn't be all that useful to store a lot of data. Would be great if something as quick as redis could work with large data sets.

Storing a list of 1.7 million strings for us takes 70mb stored in memory. Testing for membership is an O(1) op. Very happy with it. We use mongo as a dumb data store as well as a bunch of other infrastructure tools, like http://circleci.com we could have only dreamt of years ago.

Doesn't Google already have this? Go to... Show Search Tools -> All Results -> Visited Pages

I'm pretty sure that's only for filtering pages visited via a prior google search

In theory Chrome lets you search through your history for pages, but it doesn't seem to actually work very well for me.

Obvious point to raise: the reason people regularly delete their browser history is because they watch porn without turning on private browsing. How do you propose to deal with this? You'd need to provide at least the ability to selectively delete portions of the history. But you can selectively delete portions of your browser history too, and people don't - because it would be too easy to miss something. Instead, th…

Wouldn't one simply use one specific browser, say either safari or firefox or chrome, and only that browser for their... unsavory activities? I think that is a great way to keep accounts separate and keep "bad" sites from knowing about "good" sites and vice versa. Just saying. Not that I partake in any such unsavory activities.
