Alternatively, you can try using a different browser such as Opera Browser.

It’s a considerably lighter package than Chrome and using add-ons like the VPN and built-in ad-blocker results in a faster and more responsive internet experience.

Furthermore, using a VPN in tandem with decent antivirus software is only the beginning of a safe web experience.

Opera also offers data savings through compression technology that is not found in other browsers.
