Hello!
I am using Opera almost 20 years. I liked better the old Opera before the Chromium base, but still I using Opera. But this Opera One is awful, really unstable and functions does not work at all.
The adblocker does not work at all! It is very irritating and time wasting the ads in Youtube. Many times I do not watch the videos because I do not want to wait to finish the ads to make me brain dead.
I use many browser tabs above. Many times when I drag&drop a tab to make a seprate new window to my other screen (I have 2 screens) I got crash, and Opera is closing, I loss every process.
I am thinking to change browser, if things will not change.
