Integration in GitHub Code spaces stopped working in Firefox with 1.6.6

[marchof]

First of all thanks for providing this very useful integration!

While using the extension for GitHub code spaces we noticed that since 1.6.6 editors are not working any more in Firefox browser. Just a empty editor tab is shown. When downgrading to 1.6.4 everything works as expected.

In Chrome 1.6.6 works as expected.

I can't spot any suspicious error messages in Firefox. Please let me know if I can provide additional information.

It loads for me:

Can you make sure you don't have the insiders version of the extension installed?

Not sure how to check, this is how my devcontainer.json looks like:

"extensions": [
	"fabiospampinato.vscode-terminals",
	"hediet.vscode-drawio",
	"streetsidesoftware.code-spell-checker",
	"streetsidesoftware.code-spell-checker-german"
