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:
firefox.config.accessibility.blockautorefresh=true
