There are just too many things that changed simultaneously. At least there should exist Opera One theme that looks exactly as the version of previous version.

@mcedro Let's say I don't like the new look. I couldn't bare with tabs that are changing widths, for example. I don't need AI, and I needed Sync to work (which didn't). So, I uninstalled Opera One and got back to v99.

@none-now I cannot trust Opera browser anymore, as I did before. This change in appearance was the worst in last 10 years, for sure.

Opera One is less functional and uglier than v99. I don't need AI, islands, contexts, etc. You should keep things simple. And, more important, you should respect users enough to offer at least theme that looks as Opera before One. There were reasons why I used Opera for more than 15 years. It was fast and reliable browser, with decent appearance and a good amount of extensions available. This change in course where Opera is headed is, sadly, something that makes me look away. Not to mention that syncing of passwords and bookmarks didn't work after not wanted update... Look how many negative comments just in this section you have? People are looking for solution (and we found it) how to revert to v99 and disable updates. Nobody wants a browser that's stale, and might loose features over the time because it's not updating. But, you are pushing us away. Make v99 updateable and Opera One avoidable. Be fair.

@makoruu I managed to do it on Win. First, I downloaded opera 99 offline istall. Then I had to disable internet, install the Opera browser, then disable auto update feature by deleting some parts from the program folder. Very cumbersome process. There should be an option to disable auto-update. Very bad UX, and even worse UI on Opera One. I really don't like it.
