The web is a lot nicer without ads all over the place. There are a few tools out there that are designed to remove ads from your web experience, some more functional than others. I've tried a few, and by far, the best is Ad-block plus which is only on Firefox. There's an add-on in Chrome called ad-sweep, but I've tested, and there's still a lot of ads that come through. Too bad, since I really like Chrome otherwise. Ad-Block Plus is easy to install, so I'll just direct you to their website: http://adblockplus.org/en/
Alternatively, you can just click tools, add-ons, get add-ons, and search for "ad-block plus". You'll want to subscribe to the "EasyList" to get current lists of ad urls.
You can temporarily disable it from the icon that it puts in your web browser. Typically I hate adding toolbars or anything to my web browser, but this isn't that big, and is a must since the only thing more annoying than toolbars is ads.
Below is an example of with and without it enabled. You can test it on this site. I know this is reducing traffic to my ads, but trust me, I'm not making any money on them anyways. Actually, I think I'll increase the amount of ads to encourage you to either click on one or install ad-block.
There's also something called flash-block, that will block flash ads, but I don't see a huge number of flash ads, and it's annoying to have to allow all kinds of flash animations.
I've now converted to Google Chrome since I've found "AdBlock" for it: https://chrome.google.com/extensions/detail/gighmmpiobklfepjocnamgkkbiglidom
