I'm testing Opera Air, but the light mode is tiring for my eyes; a dark mode and forcing dark mode on websites would be a plus. Without it, I have to stop using Opera Air.

10 minutes later, my eyes were tired and burning.

Medically, I have to stop using Opera Air. If it had a dark mode, I would continue to use it because I prefer it among the three versions of the Opera browser.

I'm going back to Opera One and Gx.

@rulitawyn: for my security: easy: I don't go on my Bank or health site via this browser (Opera GX) ; I'm using another (Opera ) ; like that I'm sure to be in security. then I can put this extention on this browser safely and when I need to be in private with only my eyes... change and be safe !
