Loved Opera back in the day. It had "page specific settings" that would let me allow to set HTTP/Socks5 proxies on a per-page setting - today you cannot even set a proxy anymore without changing your system settings (not browser settings).
If anyone asks, I used this heavily to bypass country blocks/redirects on a per-page level and also with privoxy on some privacy invading sites.
