Sorry, to be clear, it switches all of your windows like a separate desktop. I like having both windows available simultaneously. I realize this is a nit picky complaint, and I am in the minority.
You can run the embedded Linux and then run Firefox there. Also, with multiple workspaces now supported I'm funded less reason to grab the mac (bettertouchtool being one thing). I even have vscode running full screen in another orksoace and can easily swap over.
