Profile/user manager? Program

Hello,

I am searching program wich will give me an option of changing profiles/id’s in internet.
It should look like:
1. John Smith - login
2. Rebeca Simons - login
3. .... - login
4. .... - login

And so on.
That i could log in to each profile sepratly (add proxy there for each 3 users) and for ex. Get accounts on YT / FB / portals with opinions / adding any content on pages.

So it would be long term id’s not only for one move.

I know there are bots for yt / fb - i am searching something wich will give me more freedom with ather moves in internet. (Not only with 1 platform).

Do you have any ideas? Are you using for ex. Chrome with extansions?

You can likely achieve that with firefox/chrome user profiles. Few years ago I had 50 firefox profiles running concurrently so I could be logged into different accounts on same service simultaneously, all with their own proxy per browser profile.
For the "portal effect" idk of any tool, but you can design a simple html site with links to those things. Set it as browser homepage.
