Pop-ups are used for online advertising. Pop-ups normally appear as a new browser window that opens without your consent and contains links in the form of offers and invitations. These links redirect you to other sites in an attempt to increase their Web traffic. Google's browser, Chrome, comes with a pop-up blocking feature, which is activated when the software is downloaded and installed. Chrome does, however, allow you to turn off the blocker, recover the blocked pop-ups and make site-specific exceptions.
Click on the "Tools" drop-down menu at the top right corner of the browser window under the close button. It looks like a wrench.
Select the "Under the Hood" tab.
Click on the "Content Settings" button under Privacy.
Select the "Pop-ups" tab.
If it is not already selected, select "Do not allow any site to show up (recommended)" to block pop-ups or "Allow all sites to show up" to disable the blocker.
If you want to allow or block pop-ups from specific sites, click on the "Exceptions..." button under the Pop-ups tab.
Click on the "Add" button to add exceptions or "Edit," "Remove" or "Remove All" to edit or remove existing exceptions.
Type in or copy and paste the source or "pattern" you want to block or allow. To edit or remove exceptions, click on the exception.
Select "Allow" or "Block" from the "Action" drop-down menu.
Click "OK" to confirm your choice.
Click "Close" on all tabs and windows you opened to save your settings and changes.
When a pop-up is blocked you will see a notification in your address bar.
Click on the pop-up notification icon.
Select "Always show pop-ups from (site)" if you no longer want this pop-up blocked. This will add the site to your exception list.
If you no longer want to see pop-ups from this site, remove it from the exception list.
In addition to being annoying and disruptive, pop-ups can pose an information security and privacy risk. Unless you are visiting a site you trust, it is best not to allow the pop-ups to open.
