A quick and easy note-taking solution for Pale Moon. It is a fork of QuickFox Notes by InBasic.
Can be launched through 3 options in the toolbar button (new tab/app content/new window), by typing about:notes in the URL, or by launching Pale Moon with -nst as a command line argument. It also provides configurable icons for the status bar for quick launching and sync with different file sharing services.
Simply download the contents of the "src" folder and pack the contents into a .zip file. Then, rename the file to .xpi and drag into the browser.
