While working with the multi-file-upload feature, an old school mp3 player appeared in my mind's eye.
manifest.json The add-on uses browser 'tabs' permission to load a background script, which opens the HTML page.
background.js Loads the HTML page, which loads the JavaScript scripts.
index.js - DOM Audio, video context and element creation.
playlist.js - Multi-file-upload feature creates a playlist. Forward and backward buttons are disposable to get rid of the event listener in case of a new playlist creation.
Favicon (rotating default_icon) and buttons are SVG files created with Inkscape.
Spectrum analyzer reads data from 'analyserNodeTwo' and is is driven by 'requestAnimationFrame'.
'analyserNodeOne' will be used by a bigger analyzer show in the future.
Clone the repo.
FireFox 'about:debugging', and 'this FireFox' select a new temporary Add-on.
Open the PlaylistBooster manifest.json and then start the Add-on from the puzzle icon list.
Clone the repo.
Install 'web-ext' "https://extensionworkshop.com/documentation/develop/developing-extensions-for-firefox-for-android/".
Install Android Studio latest and create a dummy project. The device manager is needed to run a Android Virtual Device (AVD).
You then want to download the FireFox apk file and drag it onto the AVD. Search "Firefox Nightly for Developers". If you find 'APKmirror' save, go there. Else use the registration process to enable PlayStore to pull FireFox Nightly, into every AVD.
Note
Deinstall FireFox 'regular' version, if any.
Open a terminal in the root of the repo clone, to load the Add-on into the AVD via USB.
@PlaylistBooster$ adb devices -l
List of devices attached
emulator-5554 offline
@PlaylistBooster$ web-ext run --target=firefox-android --android-device emulator-5554 --firefox-apk org.mozilla.fenixThe AVD and FireFox Nightly must be USB enabled (Dev mode) then.
Drag some media files into 'Device Explorer' in 'Android Studio'. Use 'mnt/sdcard/Music', to see it in user view on AVD.
Bring your earbuds to the limit. Push the preamp to 500%. This feels like 20% louder.
Works with bluetooth headphones!

(A) FF video element will stop playing at all, if the PlaylistBooster tab is in the background and you want to bring it to the foreground.
(B) FF video element will stop playing if the PlaylistBooster tab is in the background and you open another website.
Temporary solution: Press app reload button.
FireFox Nightly MUST have an open tab (i.e wikipedia) before you can see/click the ( <temporay> web-ext ) Add-on in the Extension bar.
