Opens a list of URLs with concurrent opened Tab number limit, so you never run out of memory as long as the queue size not too big. The badge would show its state if you click start button, WA means waiting for queue, and number means how many URLs in the queue.
The URL list is one URL per-line format, the extension will remove duplicated ones for you. Don't worry for repeating copy-paste bunches of URLs into browser, this extension just one click. As soon as Tab number not exceeded queue size, new Tabs will be created!
