Switch to Brave browser and it will automatically solve a long list of obnoxious impositions from websites, without needing to configure it in detail.
I agree... I like Brave also. And it can be installed on Linux...

I have tried Brave, the pop up problem is somewhat better, however I was not impressed overall with their service. I find that AdBlocker does an exceptable job.
