I created an addon to see a webdav share right from a browser https://addons.mozilla.org/en-US/firefox/addon/webdav-browser/
Now I wish to make it handle all links with protocol dav:// davs:// and webdav:// webdavs://
I have to capture all four of them because the dav protocol schema looks like not specified and different tools use different schema e.g. LibreOffice webdav:// but GNOME nautilus dav://
I found that for PWA is should be somewhat possible
But the dav schema is not listed in permitted. Can it be supported by a browser in future?
Also I didn’t get when and why the ext+something schema may be used. Is it intended for extensions/addons?
I tried to use the web+dav schema in the manifest.json but I didn’t worked. Chrome reported the protocol handler as error in manifest.
Probably it should be used only for PWA but it looks like the feature is curently just a proposal https://discourse.wicg.io/t/proposal-url-protocol-handler-registration-for-pwas/4276
I didn’t read the thread yet but anyway I need to handle the dav links.
