Add API to manage browser extensions (enable/disable, list, access extension info)

[mitttel]

Hello 👋

I’ve been trying to manage extensions in CEF using cef-rs, but I couldn’t find any available functionality for this purpose.

Specifically, I would like to:

• Enable and disable extensions programmatically
• Get a list of all installed extensions
• Retrieve information about each extension (e.g., name, ID, version, permissions, etc.)
• Access and interact with their interfaces directly within the browser context

Currently, extension loading is done via command-line arguments in cef-rs, but that approach offers no fine control once extensions are loaded.

It would be great if there were an API or example demonstrating how to:

• Enumerate all loaded extensions
• Dynamically enable/disable them
• Communicate with their background scripts or content scripts

Questions:

• Is there currently any way to achieve this with cef-rs or the underlying CEF API?
• If not, would it be possible to expose this functionality in future versions of cef-rs?

Thanks for your work on this project — it’s been incredibly helpful for integrating CEF into Tauri! 🚀
