Hi, i mage it on chrome but seems a bit different on Opera. i explain :

When you use omnibox serach feature, you can select in parameter wich provider you want as Google, Yahoo, Duck Duck Go, Amazon, and more...

You can too create a custom serach provider as i want and make : EncryptedGoogle
like
https://encrypted.google.com/#newwindow=1&q=%s
or
https://encrypted.google.com/search?{google:RLZ}{google:acceptedSuggestion}{google:originalQueryForSuggestion}sourceid=chrome&ie={inputEncoding}&q=%s

But i can't choose this new one because it seems be the same as defaut Google who use my native language FR. It's very usefull for me to use encryted version in photos reserach because it open differntly ion box other than a link to an url like old method...

If you have any tips
