I would recommend installing adblock, yes.
If your AdBlock program has blocked YouTube, you may want to disable the program. Ads displayed on YouTube help power the content creators too, so you may consider disabling AdBlock for the future too.
Open Firefox (after downloading Adblock Plus from the add ons) Tools | Add-ons | Extensions | Press 'Options' on Adblock Plus | Filter | Add Filter Subscription
It's Adblock or Adblock plus. Add ABCnews.go.com to your adblocks whitelist and then no problem.
What I did was download an app called Adblock. Go to the Google Chrome webstore and search for Adblock and install it. Then download the Privacy Palette (Adblock + Security). There are also other options like always deleting cookies etc.
If you have Firefox or Chrome installed, you can download Adblock Plus for free (just search it). I use Adblock Plus and have never had to watch a video ad on Youtube.
Use the Firefox Add-On, AdBlock.
You can download "Adblock" an ad blocking software for Google Chrome Directly from Google. If you are using Firefox you can download "Adblock Plus" from the site Mozilla Add-ons.
Try installing the "Adblock Plus" plugin/extension.
If you use Google Chrome, then go to the chrome web store (chrome.google.com/webstore) and search for 'AdBlock'. AdBlock will block ads on your page and ads lag you most the time.
It is completely safe, I use it all the time, it's great
