If you want to be more secure and anonymous then setup a boot USB for Tails and use that with the Tor browser... Even that won't be full-proof alone though (plus your ISP may become suspicious even if you are not doing anything shady since they'll be able to see you are connecting through Tor unless you have another layer of encryption before the Tor network - such as a Virtual Private Network being used as well). Thanks for sharing this, it was an interesting read!
