--- Comment #2 from Michael McMahon <michael at gnu.org> ---
Thank you for providing more information!

The reason I bring this up is because I am still seeing Falcon users use
Chrome/87 from 2021 in 2025. Maybe this is due to old LTS distro versions or
maybe Falcon is pulling from the "Chromium version" and not the "security
patches up to Chromium version" number in qtwebengine.

```
Based on Chromium version:                                      87.0.4280.144
Patched with security patches up to Chromium version:           135.0.7049.95
```

Snippet from
https://code.qt.io/cgit/qt/qtwebengine.git/commit/?h=5.15.19&id=a5d11cd6f8c487443c15c7e3a6cd8090b65cb313

Removing Opera is a good move.
