Sometimes, small tweaks can make a big difference! The app.properties file is your backstage pass to customizing Multilogin 6.

Editing this file gives you control over how the app functions, enabling you to optimize it for your needs. Plus, it’s super easy – you don’t need to be tech-savvy! All you need is a basic text editor, like Notepad, to open and update the file.

Just remember: any changes made here won’t take effect until you restart the app. So don’t skip that last step!

How to edit the file

app.properties

Windows

Close Multilogin
Go the C:\Users\%username%\.multiloginapp.com directory
Open the app.properties file with any text editor (for example, Notepad)
Make the necessary changes and save the file
Launch Multilogin again and the changes will apply

Alternatively, you can go to "My account" in the Multilogin app and click "Open logs directory", then close Multilogin. In the window that will open, go one folder up. Afterwards, proceed from step 3.

How to use browser flags

Mimic

The app.properties file lets you start Mimic with tailored command-line options (flags), giving you more control over how it runs. Here’s how to use it and some handy examples:

To customize Mimic, add this line to the app.properties file:
chrome.console_arg.{flag_name}={value}

Example options:

Disable all notifications in Mimic:
chrome.console_arg.disable-notifications=true
Enable detailed Mimic logs (useful if MLA debug logs don’t show errors):
multiloginapp.mimic.debug=true
Turn off pop-up blocking:
chrome.console_arg.disable-popup-blocking=true

Stealthfox

The app.properties file allows you to start Stealthfox with custom command-line options (flags), giving you flexibility to tweak its performance.

To configure Stealthfox, include this line in the app.properties file:
firefox.config.{flag_name}={value}

Example options:

Disable images (prevent image loading):
firefox.config.permissions.default.image=2
Block page auto-refresh:
