Currently, the plugin supports only Chrome. Attempting to use a button which invokes a clipboard action yields errors in Firefox and Safari:

• Firefox: 'name' member of PermissionDescriptor 'clipboard-write' is not a valid value for enumeration PermissionName.
• Safari: The server returned an unexpected response! Status: undefined

Behavior in legacy Edge and Chromium-based Edge is not known at this time.

Firefox does not yet support requesting permissions for clipboard-write and clipboard-read:

For example, Firefox does not yet support the "clipboard-read" and "clipboard-write" permissions, so access to the methods that access and change the contents of the clipboard are restricted in other ways.

Firefox supports only a few query-by-name permissions: https://dxr.mozilla.org/mozilla-central/source/dom/webidl/Permissions.webidl#10

Unsure of Safari's and the Edges' support for those permission names.

Resolution of this issue should include the move to a more widely-supported JS clipboard library that implements polyfills for older browsers and Firefox, Safari, and both Edges.
