I use Adblock Plus, EditThisCookie, User CSS, and my favorite...Long Press New Tab (which requires Download Chrome Extension since it's a Chrome extension).

I use User CSS to change black backgrounds to white on sites I visit frequently.

I use Adblock on all sites, except those that have no animated adverts.

I use EditThisCookie to block cookies on a few sites I frequent that annoyingly ask for "assistance" after a few visits.

Long Press New Tab should be integrated into Opera. I think it was at one time actually. It's a must-have for all browsers and I will not surf without it.

I'm just surprised and disappointed. The i5 SP4 is a really nice computer, more power than I really need. It even plays some modern 3D games ok. But Opera is painfully slow when scrolling on some sites.

For example, I really like the news integrated into the New Tab in the latest Beta versions. It works really well on my desktop (i5, AMD 390), but on my i5 SP4 the touch scrolling is really chunky. Some websites scroll smoothly, but others not so much. Does Opera really need a high end video board to get smooth scrolling?

Using MS Edge browser, all websites scroll very smoothly but it doesn't have a lot of the extensions I like to use.

Why is there such a difference? Opera should be smooth on any computer from the last few years, but the SP4 really doesn't like it.

Very frustrating to me as well. Middle-click is fine for links to open in a background, but for bookmarks why would anyone want them to open in the background? That's just stupid and I expected better of Opera designers. Just make it like the old Opera so they open in a new tab and gain focus immediately.
