How do I remove this?

P.S. Found it myself. Disable the #side-panel-full-api flag.

I complained recently about non-stop crashes with Opera 138, and discovered that the crashes only occur when Block Ads and Block Trackers in enabled in the side panel for all pages. when I disable these, the crashes completely stop. This same behavior is happening with the new Opera 139, any insight welcomed

@deathcat There's an "AI button in toolbar" option at the URL opera://settings/ai that can disable it if you don't want to disable the flag.

Hi, there, you've published versions 137, 138 and 139 within a short period of time. Have you accelerated your upgrade cycle?

Hey, in opera://activity/ I can see my other computers with opera sync enabled, but I can only see Context 1 tabs, nothing else. Since I have like five other contexts with many tabs, it would be great if I could see these too. Can you add this option?

After update netflix is unavailable. In other browser there is no problem.

@Maymorning I don't think so, I guess it's just to be more close to current Chromium version.

Has anyone noticed that the tab colors have changed in the default light theme? Is there a way to restore the previous look? The tab colors have become too warm-toned, and I liked the old version better.

@operaalx From https://blogs.opera.com/desktop/2026/11/opera-139-0-6053-38-stable-update/ :

Opera One has a refreshed look. The new rebranding is now enabled for all users, including a redesigned installer and onboarding.
