Sorry to keep harping on about it, but installing the uBlock origin browser extension could not be any easier, and it is fantastically effective.
I think it works best with Firefox, it connects and links up very easily with no issues.
It's only taken me about 4 years to realise that I could also install that combination on my phone, after unnecessarily suffering adverts and pop ups for years. And when you're a late adopter of the smart phone, they can often cause confusion or catch you out, ime. It was only when I got this pop up on my phone the other day saying "your phone is infected with a virus! Install anti virus immediately, as your security is at risk" and I fell for it.

Although, in my defense, I was completely fucked at the time.
The next day, when my head was a bit clearer, and I was more able to think properly, I later found out that it was probably merely a pop up, and that finally prompted me to look for solutions on my phone, and to discover that I could use the same Firefox and uBlock origin combination that literally stops all adverts and pop ups from appearing on my computer.
