Trying to load it on Firefox (Floorp Browser variant 11.26.0) and the examples get stuck on the `Loading` screen. Moving my mouse over it draws the cursor and leaves it imprinted on screen so you get that permanent trail effect.

In the console I see:

  Failed to load ‘https://90s.dev/os/fs/run?  code=H4sIAAAAAAAACk2QMW%2BDMBCFd%2F%2BKa4QEKAiiKlMVs1Rqlw4dmy0GjsSNsRE2TVKL%2F16DSYq3d3ef797jTas6A6zlCVgIEnhFabBL4L1TfbtP4IMVKGb5BQPUnWogzJTOHJN%2B65AQdmF8%2BiJtOxR9hfqNS65PWBFSKqkNlKqXBigE0SaeS1yWrhDFQHPfTn%2BY6HG9vjMtkyjcyP%2Fv%2BqbThp3xc%2BxEFiRr8AVWJxRCwUV1olrBkBCAnTcBmv8itXc0GOUABSvPR%2BdGVtRurtvp1fWQO86R3jYcWUvtdi668pQCGLwaGi72PYWQPWbmiCb0%2BYG6RtEboyRocxNIQ90XDTchsNJwJal1QQx5KXh5hgZ3mR9e0IvV1gfFKtaaSI7JHSYQKwisHMDwBvUhHhZHZf6q2Z1X%2B1HtMh9STmJCpqzTWpW99uHGfz0j7XEYAgAA’. A ServiceWorker passed a promise to FetchEvent.respondWith() that rejected with ‘TypeError: Array(...).keys().map is not a function’.

Seems to work fine in Chrome though.

Thanks for letting me know. Hmm, I don't know what Floorp is doing differently. I'd need more of a stacktrace. It works in regular Firefox though. Feel free to paste a stacktrace and/or stacktrace screenshot on the issues page and I'll take a look.

I have the same problem as OP on regular Firefox ESR.

Just fixed! Thanks for the feedback.

It should be fixed now! Can you try it again?

Tested and it works now!
