It would depend on your VPN, yes, but your ISP always tracks you the moment you connect, and not all VPNs are private enough or good enough that they can hide your trail. You've got to do a lot more than connect to a VPN these days (unless it's a good one). Every visit leaves an electronic breadcrumb.
Good VPN extensions ...
If you mean with "good VPN extensions" browser plugins which says they are VPNs then you are wrong. Such extensions are not really VPS, they are proxies which claim to be VPNs. That's why they are for free. If you want to have a good VPN you need to sign a plan at an established VPN provider.
