⚡ Recommended focus areas for review Method Visibility The UninstallAsync method is marked as internal while it's being called from the public Extension class. Consider making this method public for consistency and to allow direct uninstallation without going through the Extension object. internal async Task UninstallAsync(Extension extension, UninstallOptions? options = null) { var @params = new UninstallCommandParameters(extension); await Broker.ExecuteCommandAsync(new UninstallCommand(@params), options).ConfigureAwait(false); }

PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Impact
Possible issue	Fix inheritance contradiction The InstallResult class inherits from EmptyResult but also contains an Extension property, which is contradictory. Either make it a standalone result class or ensure it properly extends the base class without conflicting behavior. dotnet/src/webdriver/BiDi/WebExtension/InstallCommand.cs [44] -public record InstallResult(Extension Extension) : EmptyResult; +public record InstallResult(Extension Extension); Apply / Chat Suggestion importance[1-10]: 2 __ Why: The suggestion assumes EmptyResult means no properties are allowed, but this may not be accurate. Removing the inheritance could break expected functionality without understanding the base class purpose.	Low

Test fails on CI, because I don't know how to prepare test data in bazel test environment. It passes locally in IDE and dotnet test.

[IgnoreBrowser(Selenium.Browser.Chrome, "Web extensions are not supported yet?")]
[IgnoreBrowser(Selenium.Browser.Edge, "Web extensions are not supported yet?")]

They should work for Chrome/Edge if you start the browser using the flags:

--remote-debugging-pipe
--enable-unsafe-extension-debugging

The Python bindings added a property on Chromium's Options class named enable_webextensions that a user can enable to set these flags.

I managed it and now we are able to execute tests in different environments (dotnet test, bazel test, IDE).

--remote-debugging-pipe argument breaks CDP.
