Why do I have excessive advertisements in Chrome and Firefox?

[Kashif]

Chrome
At top right, below "close" button you will see "3 horizontal lines" click it, then select Settings >> Extension. There you will find all the extensions your chrome is using , search & uninstall the crap extensions like (outuobox , passshow etc). you can also install "adblock" from google web store which automatically blocks all ads for you, click below

Firefox

click below for firefox ad blocker
