I don't think that we need two separate kb entries for basically the same Google Suite bug.

The current add-on is manifest v3 using background.service_worker and so it doesn't work to just try use it in Firefox.

Turning on extensions.backgroundServiceWorker.enabled let me load the extension. Even with ChromeMask I'm unable to convince Google Docs that I have the extension.

There's a manifest v2 version of the extension here: https://github.com/spspider/chrome_extentions/tree/main/ghbmnnjooekpmoecnnnilnnbdlolhkhi/1.44.2_0. When I load that it into Chrome it appears that offline docs still works. It might be a better starting point to figure out what the addon is for than the current v3 one.

It looks like the extension loads something like https://docs.google.com/offline/extension/frame?ouid=u8a295c2e01086a58 which loads https://docs.google.com/static/offline/client/js/2091686874-frame_bin.js where the meat (calls to indexdb etc) of the offline implementation lives.

It looks like docs.google.com communicates its intent to the extension with messages and externally_connectable
