It's a Firefox Add-ons called Typefill

It is for those who are tired of typing the same replies, sign-offs and notes over and over, that is what Typefill is for. You save text with a short code, type the code in almost any text box in Firefox, and the full text goes in. If parts change each time, like a name or a date, it asks you first.

Free with no limits, snippets sync through your Firefox account, and nothing you type leaves your browser. The free version is open source (GPL-3.0). There's a Pro for if blocks, formulas and Google Sheets data, but you don't need it.

Feedback very welcome.

I just got tired of being asked for premium to keep the songs on the playlist going.

So I created a Firefox add-on for my Android phone and it works fine for me, so should anyone be interested, try it and if there are issues let me know.

It keeps YouTube and YouTube Music playing when you switch to another app or go to the home screen, and it moves your playlist or mix on to the next video or song.

It's free and open source (MIT), doesn't track you and needs no account. The code is here if you want to check: https://github.com/lagudafuadtosin/plays-on
