Our extension (ID aoghjeonfkfhkldgoajobcepfjmdinff) is "only" waiting for around a week and after it was approved on Chrome and Firefox within just a few days, I was searching how long we can expect for Opera - so I was ending up here.
But looks like some extensions are waiting for years apparently, this is pretty ridiculous!
While the user base of Opera is not that big, I kind of liked that browser, so I thought we just submit it there as well.
But looks like we as developers should just consider Opera a "dead browser" and stop wasting our time with this here - what a pity!
