Its latest editions Mozilla Firefox displays ads on new tab icons. If you are one of those who can't stand them, you can easily get rid of them.
The Mozilla Foundation added these ad tiles to reduce its revenue dependence on Google, which had been their main source of revenue for many years, due to search of Google which was the default search engine in the browser Firefox. The Mozilla Foundation, however, chose not to renew its partnership with the company, and as an alternative source of revenue, decided to place ads on each new tab page.
Mozilla claims that these new ad slots do not jeopardize your privacy, that is, they are not used to track your activity or collect third-party information. However, some of you may not want to have them on every new tab you open.
To get rid of your ads, do the following:
Open a new tab in Firefox
Make it click on the gray gear icon in the upper right corner to see its menu and select it choice "Classic".
You're done. With Classic, Firefox will only display webpages from your browsing history on the new tab page. Note that tiles already existing and displaying ads will not be left alone. You should remove them yourself.
Εναλλακτικά, αντί της επιλογής Classic, μπορείτε να επιλέξετε το "Blank", αλλά η νέες καρτέλες σας θα εμφανίζονται κενές, κάτι το οποίο τις καθιστά λιγότερο χρήσιμες.
