Solution I am working on

to get the binary path of browsers I am using pybrowser made by roniemartinez. My original plan was to create my own library but since its already i will be using this

Chrome

This is already done in mitmproxy

Firefox

There are 2 methods to get firefox I am not sure if second one is good or not

• enumerating well-known paths and executable names
• If platform is windows firefox may be installed in some other locations so i am using powershell to get firefox path

(Get-ItemProperty -Path 'Registry::HKEY_LOCAL_MACHINE\Software\Clients\StartMenuInternet\Firefox-*\shell\open\command\')|findstr "default"

(default)    : "C:\Program Files\Mozilla Firefox\firefox.exe"

then using regex to get path

mkdir %USERPROFILE%\AppData\Local\Mozilla\Certificates
for installing a certificate in Firefox .pem has to be copied
https://wiki.mozilla.org/CA/AddRootToFirefox#Installing_Certificates_Into_Firefox

cp mitmproxy-ca-cert.pem %USERPROFILE%\AppData\Local\Mozilla\Certificates\mitmproxy-ca-cert.pem

firefox --profile "<custom_pref_folder>/pref"

for firefox profile and proxy setting
https://wiki.mozilla.org/Firefox/CommandLineOptions#-profile_.22profile_path.22

all the steps will spawn a proxy configured firefox

Safari

I don't own a mac so can't do much here
if anyone wants to help it would be really great

Android

I have limited knowledge of android so will do more research

Docker-containers

setup proxy for all containers docs
by having these options in this config
~/.docker/config.json

{
 "proxies":
 {
   "default":
   {
     "httpProxy": "http://192.168.1.12:3128",
     "httpsProxy": "http://192.168.1.12:3128",
     "noProxy": "*.test.example.com,.example2.com,127.0.0.0/8"
   }
 }
}

I have created an addon docker.py with 2 commands

• docker.enable : This will append the proxy object in the config and write it in the files
• docker.disable: This will remove the proxy object from the config and write the file

docker Image has to be recreated or start new containers so that proxy is being used.
user has to copy the mitm certificate in the /usr/local/share/ca-certificates/ either manually or via Dockerfile
