Clearly mark pre-configured browser session with proxyman certificate

[omdathetkan]

Description

Firefox supports remote debugging. When a browser session is started, this is clearly marked as such:

For example as used by the VS Code debugger plugin:
https://marketplace.visualstudio.com/items?itemName=firefox-devtools.vscode-firefox-debug

If the feature "Open pre-configured web browser with http proxy and trusted certificate" is used, it should leverage this UI.

Why this feature/change is important?

Improve security by making the user aware what requests are being decoded.
