glad I found someone already made this suggestion
I was waiting forever for this to be included in opera, until today I decided that I cant just wait and tried to find a way to contact the developers for this

anyway if the suggestion isn't clear, there should be another option beside "go to webpage" that open the link in a new tab when I right click in the highlighted link

I know I can open any link in a new tab but only if it was clickable not highlighted
