I use Firefox almost exclusively, and have done for years. But there are sites that only work with Chrome. So far I've always either:

(a) Ignored them, or

(b) Used an incognito window.

But now, when I'm forced to use Chrome, I'm seriously looking at disguising my IP address, etc. But this is not my field.

Would a VPN do what I need? Where are instructions that a n00b can follow?

Every site I've found so far has either been:

(i) Advertising;

(ii) Assuming too much competence;

(iii) Out of date, or

(iv) Wrong.

Clear, robust, and up-to-date advice welcome, as I'm sure it would be for many.
