My Firefox was getting so bogged down in ads it wasn't funny. Switched to Chrome which handles Adobe Flash somewhat better, but even that was getting too many ads. Finally installed Adbock Plus on all the browsers. It makes a HUGH difference. Only very rarely does it disable something I need and then if you think the website isn't working right, you can disable Adblock Plus temporarily. Sorry to any sites that depend on ads, but the garbage out there makes surfing too annoying.
