I want to stop the adverts popping up on the side of my laptop

A pop up does as described, it pops up whilst viewing a web page. An advert is usually displayed just as a web page is opening.
Use a program like Adblocker to stop that from happening.

Activate pop up blocker in windows or use a good third party pop up blocker!

Get an ad/pop up blocker off the internet or pc world.

use an adware prevention software.
See here for a free version.

Hi, i use firefox as my default browser and install an add on called adblock plus, blocks most pop ups and adverts, you can disable on chosen pages

Those banners and adverts are embedded on the websites that you access which you cannot prevent. You can only prevent pop ups.

Hi Ken,
Block the pop-up windows by:

• Go to tools option on browser menu.
• Click on options.
• Select on content.
• Check the 'block pop-up windows option' by clicking inside the box.

Hope this helps.Thanks!

Facebook's revenues come from selling ads. Other than certain web browser addons, there's no way to remove the ads from Facebook's pages. But If you have Active X or download it and click to protected mode it will stop the adds from popping up, but will keep the regular side adds. the pop up will come on the first time you log in but if you click the little Lock emblem on the bottom right it will engage and stop pop ups, which are running on a spyware software.
Hope this helps.

You are not alone. Yahoo blame the service ISP eventhough Error 504 pops up.
I have set Yahoo to POP to Thunderbird. No adverts and much faster.
