I switched to cunning animal at the begging of the year, however didn't completely give up on Opera. In the recent months I've switched backed to Opera and have used it concurrently with a certain cyan-iconed browser that recently switched to chromium. I steel feel like Opera is the true browser because I've used it as my primary(probably the first) since I'd started using the Internet, however I just can't get past by recent shenanigans...

If I accidentally zoom in or out, I won't be able to reset it back to normal unless I clear sit setting at opera://settings/clearBrowserData. Ctrl+Shift+B still opens broken popup, but now if you turn of that useless sidebar, then it will open bookmarks in another window.

History or any other pop up tab doesn't open.

Since the 49.0.2705.0 there's been high CPU usage by Opera, especially when more than one window is opened.
