How to make simultaneous execution of actions on multiple tabs at the same time?

Question

Google Chrome

There are many tabs that require multiple repeated clicks. How can this be implemented?

Answer 1

You need to write a browser extension. From the background extension process, send a signal to the content scripts on the tabs so that they feed what you need, as a result, clicks will occur simultaneously.
But they don't usually do that. It’s more reasonable to debug the site code and understand what requests go when you click on the buttons you need, and then stupidly repeat them directly into as many threads as you need and you won’t need to create a million tabs for this, one will be enough.
