Step 1: DOWNLOAD FIREFOX!!!
Do not hesitate to download the fastest, safest, and most reliable web browser. Internet Explorer and Chrome (even the newests versions) are loaded with bugs and security issues.
Step 2: DOWNLOAD/INSTALL ADBLOCK PLUS (A Firefox plugin)
Head over to here: https://addons.mozilla.org/en-US/firefox/addon/1865 and click on "Add to Firefox". Press 'Allow' in the drop-down block at the top of the browser. Click 'Install'. You will need to restart Firefox.
Step 3: ADD FILTER LIST SUBSCRIPTION
When Firefox restarts a new tab opens asking you to choose a filter subscription. If it does not go to this link; chrome://adblockplus/content/ui/subscriptionSelection.xul
Choose either EasyList (English) or Fanboy's List (English). Press 'Add Subscription'
Note: If one of the lists does not block the ads try the other.
Then your DONE. Ads should not appear in the stream.
