Firefox stuck with 0.19.44

[tmistele]

I updated to 0.19.44 and noticed that Pluto doesn't load correctly in the browser. It's stuck at the following screen:

I'm using Firefox and it seems the issue is the navigator.userAgentData used here

Pluto.jl/frontend/common/KeyboardShortcuts.js

Line 2 in b146dcc

export let is_mac_keyboard = /Mac/i.test(navigator.userAgentData.platform ?? navigator.platform)

Perhaps the fix is to simply insert a ? like this?

/Mac/i.test(navigator.userAgentData?.platform ?? navigator.platform) 

Downgrading to 0.19.43 fixes the issue.

I ran into the same issue with both Safari and Firefox.

thank you for the report, a new release will be tagged with the fix.
