I really loved the old UI of Opera, now you can't even see if the back button is greyed out or not. Also Ctrl+F on the start page is gone for whatever f'ing reason. Is it safe to downgrade? Are there security risks? If yes, how do I fix the aforementioned problems?
PS: How do I make Ctrl + F always open a new page? I hate it when it jumps back somewhere, especially, when I have 3000+ tabs open...
