Exclusions
If a certain profile causes issues for you, you can exclude it from being used with a random profile option. If there are no profiles that can be used (you excluded everything), your browser profile will not be spoofed.
Random Profiles
You can select a specific profile to use with all sites, or use the random profile options (desktop, profile, either).
When using a random browser profile, you can choose how often to change your profile. There is a custom interval opton so that you can specify the interval range.
For example, if you want to use Random Profile (Desktop), your profile will be a browser on Windows, macOS, or Linux and the screen resolution (if you select the "profile" option) will be a desktop resolution.
Whitelist
If you'd like to use a profile with a specific website, check out the whitelist section.
