@briton , nice idea. What I've done:
- Enabled opera's VPN and changed it to the USA. (ensured that sites see me as USA user).
- Uninstalled opera from my computer without deleting my data (history, settings, etc.)
- Installed downloaded version.
That doesn't work.
One thing that is interesting is that if I use instant search immediately after browser start, it does not use Yandex. In this case, no search engine icon is displayed and Google's engine is used. But, after a few seconds or minutes, Opera decides that Yandex is the thing.
P.S.: Of course I can access Yandex and any blocked in my country site. But I just hate it as the search engine at all. It gives non-relevant result and misses a lot of features Google does not. And, what is more important, the problem is not search results themselves or features, the problem is that opera is forcing me to use what my religion does not allow to!
UPD: I've also tried same thing for bunch of other free vpn's. Same result. And I don't actually want to delete my browsing data.
