Just Refresh插件简介

Just Refresh插件描述

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 oneclick 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 (rightclick the icon, click "Options"). This way, you can simply click the extension icon in der to toggle on  off the refreshing.

The extension was designed overall to be minimal  straight to the point. It requires two permissions: 
1. activeTab: to access the current tab  start refreshing it.
2. stage: to ste the currently set interval locally. 

You can view the source of the extension here:
