Thanks for sharing, this is great. Firefox on Android has some support for bookmarklets, you can search for them in the address bar. This is more convenient. Why didn't this get more appreciation?
Bad timing on the New page, I guess. Also, after posting, a couple of days later I realized there was already another PWA for this [1]. I'm glad I didn't find it earlier though so I wasn't discouraged to build my own. I'm glad my implementation handles a certain edge case better I realized: sharing from Spotify doesn't result in a `"null"` title but `""` instead.
