On my iPad which I am using a bit lately while my W7 laptop is being repaired Ia m getting heaps of adverts. Can anyone suggest a good advert blocker? And to add a bit more, if that is okay, will it work on my wife's MacBook Air? Thanks in advance for any ideas.
For an iOS device, best I can suggest is to do a search for "ad blocker" on the App Store and pick one that you think looks good price-wise, feature-wise, and review-wise. I cannot offer a specific suggestion as I don't personally use an ad blocker on my iOS devices.
Regardless, the MacBook Air will not be able to use what ever ad blocker you pick for the iPad unless it is some sort of Internet based ad blocking service (i.e. you connect through their servers to browser the web...kind of like a VPN). You can, however, add an extension to Safari (or similar for Chrome or Firefox). Personally, I use AdBlock with Safari. You can find Safari extensions here:https://safari-extensions.apple.com
When I go to that page, there are two well know ad blockers first in the list AdBlock Plus and AdBlock. Pick one that you want and install it from that page.
