Features & Capabilities

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.

Is Profile Launcher Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Profile Launcher requires very minimum permissions.

Risk impact analysis details

Medium Facilitates communication between extensions and native applications, usually low risk if managed correctly.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Profile Launcher is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
