Well, the ad blocker has made a real difference. So much so, the difference between browsing on my computer and someone else's is now very obvious.
I'd recommend if you're using Google Chrome as a browser to look at the add-on's and down load an adblocker. There are a few available on the Chrome add-on list. They all work in the same way so I can't say which is best.
It doesn't only speed up eBay either. the local newspaper website is 40% news, 60% adverts. It's made a HUGE difference on that website too.
I would say try it and see if there is any difference. I recommend it.
I will get back to sailing related stuff soon, I promise! But making the browsing experience better for those of you searching for the ideal low-cost yacht has to be a good thing.
