This add-on is very useful. It'll get 5 starts from me when it will let me know visually which tabs I set to "stop reload" or to auro-reload :3 I suggest custom set tab-colors or maybe small icons like a small red or yellow dot. Or anything else that is technically possible.
At the moment, that is not possible with WebExtensions but more Tab customising API is planned. Please don't mark the add-on down for a feature request or support queries. Please post all support questions/requests to the support topic.
