Ledger Nano S & Firefox 85: DOMException DataCloneError in postMessage of ledgerConnect.showAddress()

In Firefox 85.0 on OpenSUSE Tumbleweed, the following fails:

this.ledgerConnect && await this.ledgerConnect.showAddress({
  params: {
    address: a,
    ...l
  },
  serial: s
})

This happens when trying to verify an address with Ledger Nano S.

Log output:

Numbers in ledgerVerifyAddress redacted because I am unsure if they might be cryptographically significant.

The same procedure works in Chromium 88.0.4324.96 and it has worked in Firefox before (I am unsure if in the same Firefox version).

Is this a bug in https://github.com/Emurgo/yoroi-extension-ledger-connect-handler/ or https://github.com/Emurgo/yoroi-frontend/ ? The message to be posted to the freshly opened window seems to be inadequately prepared.

[SebastienGllmt]

Probably we won’t be able to fix this because Ledger has dropped support for Firefox for the foreseeable future. The proper fix will be disabling Ledger entirely on Firefox builds.

FWIW @SebastienGllmt, adalite.io seems to work pretty well with Ledger Nano devices and even Trezor bridge. Maybe Yoroi is doing something different?
