Tell HN: Check medium's localstorage if you use adblock

Interesting. Something like this can be mitigated by blocking localstorage access or using container-like solutions such as Firefox containers[0][1].

A nice project to work on would be to write a Chrome and Firefox extension that could watch, notify, and store localstorage and other tool usage on a per-site basis with an admin panel for whitelisting or blacklisting sites, similar to how uBlock functions.

Personally I run a few extensions that attempt to block or obfuscate fingerprinting attempts by sites inspecting system fonts, canvas rendering, etc. Some sites break altogether with these extensions.
