Behind the Curtain
A Firefox extension supposed to help you find the backend IP-Address of a website proxied by Cloudflare.
Also allows you to gather a lot more information about the website, like querying info from crt.sh,
Shodan and IP-API.
On top of that, it also allows you to spoof the Host header of the request, which can be useful for pretending to
use a different domain, for example when bypassing some Cloudflare protections.

The logo
A big special thank you to Skittles (@skitsy. on Discord, @skitty_skits on Twitter)
for creating the logo for this extension, both the one with Cloudflare enabled and the one with Cloudflare disabled.
MurmurHash3 library
I was reading the Shodan blog on favicons and I thought it would be
interesting to create a browser extension that would hash the favicon of the current page and then search for it on Shodan.
After I started working on this, I checked if someone made a js library for murmurhash3 and I found out that someone
already made a browser extension that does exactly what I wanted to do! The extension is called "favicon-hash-browser-extension",
please check it out here, I only used the library for hashing from it:
https://github.com/michaelknap/favicon-hash-browser-extension/blob/main/src/lib/murmurhash3.js
This was after I did most code. I decided to implement it anyway, as I wanted to add a lot more to my extension anyway
than just hashing the favicon.
