Profile Launcher by Hyseki

A simple Firefox addon that lets you open new instances of differents profiles easier, even from others browsers.
This addon connects to a python script through Firefox native-messaging since addons cant directly interact with the profiles.
Addon source code and installer: https://github.com/hyseki777/Profile-Launcher-Firefox-Addon

IMPORTANT
Due to this limitation you must have python installed on your system, if using windows remember to check the Add to Path checkbox during the python instalation.
Besides having the addon you must run the pl_installer on the github repo above and that will set up the native-messaging and everything else necesary.

NOTICE
On Windows firefox cant open graphical applications from the addons, so when clicking the profile it will open a folder with a bat file inside and you must open that in order to open the new browser instance.

Create, Rename and Delete functions are Linux only.
