I need to block specific script from execution over IOS opera mini browser.
navigator.UserAgent does not allow to clearly identify this browser. It returns somerhing like this: Mozilla/5.0 (iPhone; CPU iPhone OS 7_1_1 like Mac OS X) AppleWebKit/537.51.2 (KHTML, like Gecko) OPiOS/8.0.0.78129 Mobile/11D201 Safari/9537.53
Ipad pro and iphone 5 se user agent not include nor 'opios' nor 'opr'
How to detect it correctly with javascript?
