Need support for --user-data-dir

[LiuJiewenTT]

Is your feature request related to a problem? Please describe. Some companies force employees to bring their own devices to work and force them to use some program to scan the device, which is a threat for personal information security. I tried with -profile switch, this will not allow me to switch between profiles. But here comes another problem: I can go to Settings, Profile Management, there I can switch to my local data located in %APPDATA%\Waterfox, which means I will not be able to use new feature of multi-profile will easy switches if I want to protect my security.

Describe the solution you'd like I want a --user-data-dir which allow me to indicate a location as a replacement of %APPDATA%\Waterfox, so the company will not be able to find my personal information so easily.

Describe alternatives you've considered No.
