Please provide the detailed information about what kind of tampering you noticed?
You said, In developer tools-> Other tab. But there is no other tab in the main menu of the dev tools. Other option is located under Developer tools->Network tab. Are you referring to that option?
Network tab shows the list of network requests that helps developers to find any network issues.
The options you seen for emulating different devices are for testing the web applications.
These options may not be useful for any normal user but it is very helpful to the developers.
For more information about dev tools you can refer to this link.
The URL you shared is for the developer tools and has some parameters at the end of it.
Let me know, if I misunderstand anything from your above description. I will try to correct myself and try to provide you further suggestions.
Thanks for your understanding.
