Good way to block adverts?

[Radiation]

Im looking for a good way to block adverts and unwanted site domains, I used to do this with my router but since getting a new one I can't do it like that anymore, I found blocking domains was really efficient and easy so Im hoping there's another way that doesn't require anymore than adding the main domain bit without hundreds of variations which annoying banner ads sites do.

I thought about doing it by one of the plugins for firefox but I don't really know if they're good to use and really I would like something behind the scenes but better than a massive host file because I found out it can't seem to do everything by the domain name.

I have been thinking of trying adblock for firefox but I was hoping for a seamless way to do it like I could by the router, tbh Im not bothered about ad banners from the site your visiting I just don't want outgoing connections to ads sites and other rubbish that's why the domain blocking abilities of the router were great, I would use the hosts file in xp and the long list of sites I have to block but its annoying it won't just do the full domain, also this will help for messenger and other things that like to connect to ads sites.
