TOR is terribly inconvenient, I'd rather continue to use Opera. Most users do not need it at all, as well as its use, this option is more suitable for those who are completely turned on privacy or those who have something to hide. There is a strong opinion that privacy is a myth, and if really want to, will still find you.
Why Opera and not another browser? For example, Firefox. Will Opera be able to provide a level of privacy at least close to TOR, or have you chosen what is convenient and familiar to you without giving a damn about privacy?
I disagree; you should try it out. In my experience, websites did load pretty slowly a few years back. But nowadays, it has gotten a lot better, especially if the website doesn't need JavaScript and doesn't use lots of graphics (like Bitcointalk).
I tried repeatedly. He loses on almost all fronts. Moreover, TOR itself does not provide proper privacy, without the necessary settings. I do not argue, it's a matter of habit, but for most users, this TOR will instill not a sense of privacy, but a feeling of irritation. And then they think for a moment, why the hell do they even need this privacy? For what? And after that, they will choose what is more convenient.
But other browsers also need to be configured before initial use, and not use the default settings.
Although, you can’t argue here: most users will always choose convenience and practicality over privacy.
