Version 1.1

New:
- The notifier now requires a one-time purchase. Click the
toolbar icon to buy, or to restore a previous purchase.

Fixed:
- Only the first reel after loading the page would play a
sound. Later uploads in the same session were silent.
Every upload now gets its own alert.
- Some upload confirmations were missed entirely, depending
on how Instagram updated the page.

Changed:
- Clearer messaging when the browser blocks the sound.
Browsers require a click or keypress on the page before
any audio can play.

Requires Firefox 140 or later.
