A short snippet that (still) works

Sign into your profile and open an album you'd like to delete,
Open Developer Tools > Console (Ctrl+Shift+I on Chrome, Windows),
Paste the main.js and press enter,
Proceed to your work, while keeping the tab open in your browser.

Note: the code works with the new Facebook design only, as for 2020 October. Unless Zuck changes the design/structure again, this will work.
