I access to some web site on pc but it redirect to mobile version. i try with other browser, don't have this problem. windows 8.1 64bit Vivaldi 1.4.589.11 32bit this site. www.nicely-shop.com/
It's that site that doesn't know about Vivaldi, by changing user agent to Chrome it shows the normal page.
Contact the site admin and tell him to add Vivaldi as valid browser.
Meanwhile try to add the extension and see by yourself
ok, thx u.
