Here's how to use AdBlock to hide an entire page:
- Click the AdBlock icon in the browser toolbar and select Block an ad on this page.
- Click in the outermost white space on the page (to encompass as much of the page content as possible).
- In the dialog box that opens, drag the slider all the way to the right.
- Click Exclude.
If the page has a lot of pieces, you may have to repeat those steps a few times to get them all and hide the entire page.
