Type "opera:config" in the Opera address bar and expand the "Proxy" section. Specify the IP address and port of the proxy server in the "HTTP server" and "HTTPS server" fields, and check the Use checkboxes. Click save and restart Opera.
@leocg I have a Xiaomi 12 with 12gb RAM, with just 4 apps opened, Opera reload the page even switching tabs, I always lost forms data. Chrome doesn't have that problem, nor UC. I always used Opera but this problem just annoying me 2020 to now.
@leocg Thank you for letting me know. Further, I check for backup if it is recoverable. It is necessary to keep eyes on your little brother otherwise he can involve himself in those activities that are not good for his future
@opzvaranka Yes, but I don't understand why Opera has to handle in this way and not via the Google autofill service as opera mini and all the other browsers do?
