Privacy on the Internet is important because privacy risks range from the gathering of statistics on users to more malicious acts such as the spreading of spyware and the exploitation of various forms of bugs (software faults). Many companies, such as Google, track which websites people visit and then use the information, for instance by sending advertising based on one’s web browsing history. Sometimes prices on products are changed on the same website, depending on tracking information, and two people may view the exact same product on the exact same website yet be presented with very different prices.
Considering the amount of conflict of interests and scare with using browser, I think the only, least risky way is to use someone else’s internet to browse or to use TUI browser.
Then again, a non-programmer (i.e. me) would be having difficulties. I think one of the more important aspects of security is to know what you are up against. It’s far easier to be secure on the internet if your goal is defined as “not being hacked by script kiddies” rather than broadly defining “government-agency sponsored, state-level threat” stuff.
As long as you’re not a billionaire, I think the minimum steps to undertake is to limit your use of the internet. Kinda scary for a layman like me to see the internet and see everywhere that each click can get you hacked. Again, that sort of stuff would most likely apply to high value targets anyways… which I am not.
