ProxyBrowser

[argumentum]

A lightweight wrapper that registers as a custom web browser to open links, web shortcuts, and HTML files inside the target browser's private or incognito window.

When set it as your default browser in Windows, any link clicked in external apps (Slack, Outlook, PDFs, etc.) or double-clicked HTML file is routed to "LyProxy Browser". 
The script grabs the input URL parameter and re-launches it via the configured browser in an isolated (Incognito / Private) session.

By default the script targets Microsoft Edge. You can easily switch to Google Chrome or anything else before compiling.

ProxyBrowser_v1.0.zip

Compile before running.

Why code this ?
Because I don't like the idea of opening stuff in my default browser. Because am paranoid distrusting.
