[🚀 Feature]: Support installation and uninstallation of web extensions via WebDriver BiDi

[whimboo]

Description

WebDriver BiDi now has commands for installing and uninstalling web extensions which Chrome and Firefox have already implemented. As such it would be good to get those APIs as well added to Selenium.

@whimboo, thank you for creating this issue. We will troubleshoot it as soon as we can.

Please note that in Firefox 137 we install the extension permanently which means that it's not allowed to install an unsigned or unpacked extension. This will be fixed in version 138.

"One line code" solution for .NET/C#. The primary question would be hoe to test whether an extension is installed successfully. I guess if the command executed without errors, we can treat it as success.

[whimboo]

Yes, that is correct.

We can also assert the id of the extension with the extension id provided.

@whimboo I have implemented installation and uninstallation of web extensions in Java binding. I need to wait for stable 138 Firefox version before I can PR.

@Delta456 if you don't have a signed XPI to test that I would recommend, yes. Before that unsigned XPIs and unpacked web extensions will not work.

[Delta456]

Yes, I am waiting for the version. Please ping me here when its out 😃
