One-click toggle auto-refresh
Just Refresh is an open source extension that allows you to automatically refresh a page on a set interval. You can toggle the fresh in one-click on the extension icon.
Unlike other auto refresh extensions, Just Refresh does not have a popup page when you click the browser icon. Instead, you can change the refresh interval by visiting the options page (right-click the icon, click "Options"). This way, you can simply click the extension icon in order to toggle on or off the refreshing.
The extension was designed overall to be minimal and straight to the point. It requires two permissions:
1. activeTab: to access the current tab and start refreshing it.
2. storage: to store the currently set interval locally.
