Uninstall AdBlock Plus, install AdGuard. For whatever reason AdBlock Plus causes pages to not completely load right away, so I always have to wait till I see the reload icon in the nav field before I could actually scroll the page. When I used to use ABP with Chrome and there was no delay, but I'm tired of Google so I went back to Safari. I was just about to switch back to Chrome but looked for an alternative and found out about AdGuard. With AdGuard, pages load instantly. Finally get the feeling of browsing in 2014, not 1996 on a 56k modem.
