web traffic proxy (?)

Hi, because of safety concerns I would like to be able to setup my mikrotik in this way:
I would setup my browser to connect over a secure connection to my mikrotik elsewhere in the internet, and from there the mikrotik would connect to the desired website.
In this way I would prevent anyone say on a public wifi or at work from evasedropping on my communication.
What would be the best way to achieve this? How hard would it be to setup a pc to connect to local network as usual, but use the mikrotik for any connections going outside?
