fwiw there is nothing that web extensions lack that would prevent that from working

https://developer.mozilla.org/en-US/Add-ons/WebExtensions/Na... exists to allow web extensions to talk with programs on the computer, its up to someone to write the extension and executable for that usecase

The OnePassword extension already does this fwiw.

(The webextension might be in beta? When I installed it a month ago it was in "beta" and had to be installed directly from their site, idk if they've uploaded it to the store yet)

Or to port an existing Chrome extension, as they work similarly now.
