Opera 121.0.5586.0 developer update
This week’s Opera Developer update focuses on stability, UI fixes, and split screen improvements.
Highlights include:
- O-Menu Responsiveness Fix: Thanks to reports from users on the Opera forum, developers have fixed an issue where the O-Menu became unresponsive when the sidebar was set to auto-hide and then disabled. Community feedback continues to play a key role in shaping the browser!
- UI adjustments: Better tooltip labels and popup window sizing.
- Split screen: Several bugs with tooltips, navigation buttons, and the Translate popup have been resolved.
- Crash fixes: Multiple crashes related to tab handling, closing behavior, and macOS issues were fixed.
For a complete rundown, take a look at the changelog.
