Description
The quicknanobrowser sample project seem incompatible with the --single-process mode. Not sure if it's caused by odd project settings or a latent Qt bug.
Steps to reproduce:
- Open quicknanobrowser sample project.
- Add qputenv("QTWEBENGINE_CHROMIUM_FLAGS", "--single-process"); at the top if the main function.
- Build in debug mode and start application.
- Observe Single mode supports only single profile. assertion failure during startup.

My reason for reporting --single-process problems is that I'm working in a security hardened environment where all network access is disabled by default. Firewall whitelisting is performed on an per-app basis. I then need quicknanobrowser to be able to gain network access when whitelisting quicknanobrowser.exe.
