I use Google Chrome as I have a gmail address and use Picasa for photo editing and it just makes it all more seamless. I tried Edge but couldn't get on with it at all, use Safari on my iPad but haven't tried Firefox though I believe a lot of people like it. I think once you get used to a particular browser, then it is easier to just stick with it as you know where everything is.
Back to the original adblock issue - to get it working in Chrome you will need to go the settings (the three vertical lines top right of the page) then choose 'settings' (near the bottom of the drop-down list), then the 'extensions' option on the list on the left and make sure it is enabled. You can also install the adblock extension from the 'Get more Extensions' link at the bottom of that page and then searching for adblock plus in the Web Store
Saturday morning lesson over! I hope it may help somebody ...
