In the face of recent changes in Firefox, some anons were asking for a /g/'s perfect web browser, we have collected here the most wanted features:

Granular control over incomming traffic like Policeman (more control than uMatrix in this particular subject).
Granular control over outgoing traffic like Tamper Data or like Privacy Settings (the addon).
Easy switch to preset profiles for both like uBlock Origin for incomming traffic and Privacy Settings for outgoing traffic.
Random presets generator for things like "user-agent" and "canvas fingerprint".
Custom stylesheets like Stylish.
Userscript support like Greasemonkey.
Cookie management like Cookie Monster.
HTTPS with HTTP fallback and ports management like Smart HTTPS and HTTPS by default.
Proxy management like FoxyProxy.
"Open with" feature to use an external application, like for using a video player with youtube-dl and MPV, or for text input with a text editor, and for other protocols like ftp and gopher, and even as a file picker.
Local cache like Decentraleyes and Load from Cache.
All this in a per site basis.
URL Deobfuscation like "Google search link fix" and "Pure URL".
URI leak prevention like "No Resource URI Leak" and plugin enumeration prevention by returning "undefined".
Keyboard driven with dwb features like vi-like shortcuts, keyboard hints, quickmarks, custom commands and non-bloated smooth UI.
Configuration options from an integrated command-line or in configuration files like Lynx.
A way to import bookmarks from other browsers like Firefox.
Search customization like surfraw, dwb funtions or InstantFox Quick Search, and reverse image search like Google Reverse Image Search.
Writen in C.
Low on dependencies.
Framebuffer support like NetSurf for working in the virtual terminal (TTY).
Actual javascript support so we can lurk and post in 4chan.

Any devs up to the task? Also general discussion of browser alternatives.
