A simple reading pane to save tabs you want to come back to. Saves to local storage and has a scratchpad.

In order to debug extensions you must make use of the built in 'Developer tools toolbox' found in about:debugging#/runtime/this-firefox. Load your temporary extensions manifest and click inspect. You will need the web-ext extension.

npm install --global web-ext

web-ext run

web-ext lint

web-ext run --firefox-profile or web-ext run --firefox="C:\Program Files\Firefox Developer Edition\firefox.exe"
