       | I've been curious about this. I wanted to build a "Comment on

       | much friction, and running a proxy is expensive.

       | Even if you get it working, I'm not clear how you maintain
       | privacy - Loading the whole index from remote is private but
       | expensive. Passing every URL you load to the service is cheap but
       | terrible on privacy.

       | There are middle grounds like "first 4 letters of a SHA384 of the
       | URL" or bloom filters, but I only skimmed the article and didn't
       | notice which one they're using.

         | and saves the links. When you're browsing, it checks the link
         | of the current tab against those links.
         | 
         | How it works is the last section of the blog post.
