Hello!

We’ve rolled out a new Opera Developer release, version 139, with a Chromium bump, and a wide batch of fixes across vertical tabs, sidebar, settings, and stability.

New in the ad blocker:

• We’ve added a new way to take back your page from distracting content. Right-click any ad, banner, or annoying box and choose Block this element, it disappears instantly. Need to tidy more at once? Pick Block multiple elements to highlight and remove items one by one with a crosshair, with a small slider to catch repeated blocks like ad rows or card lists. Everything is instantly reversible with an Undo button, and your blocked items are remembered per site, so the clutter stays gone on your next visit. Wipe it up! is built right into the Opera ad blocker: no setup required.

But in our regular release:

• Updated Chromium to 154.0.8037.17
• Enabled #popup-protection : only one pop-up can be displayed at a time now, and extended the mechanism to cover all pop-ups
• Added drag and drop for the auto-hiding vertical tabs panel, both within the same window and across windows
• Fixed WebCodecs H.264 encoder errors on web.whatsapp.com and Paramount+ video playback failure (Error 100)
• Fixed websites not reacting to touch on touch screens
• Fixed sidebar remaining partially visible (a 4px strip) after auto-hide
• Fixed missing options that prevented Opera account synchronization
• Fixed a number of crashes across autofill, AI panel, DevTools, tab collection, and the Windows installer
• A round of React Settings polish: added favicons, fixed missing icons, search results for “Browser Connector”, and the “Automatically translate these languages” section

Known issues:

• Clicking the “+” button in the tab tooltip does not let you select additional emoji, we’re working on a fix.
