Load multiple pages into a single tab in web browser

Hi all, I have an idea and need help creating some script to do this. Let's say I have some web pages that I want to switch automatically on my web browser. i.e. 1. [login to view URL] 2. [login to view URL] 3. [login to view URL] 4. etc etc Right now I'm using a Chrome plug in that switches the tabs every so often (let's say 30 seconds). The problem is that I have to load the pages that I want in different tabs and they are switched all in a constant time (30 seconds), and if I want to add a new page I have to go to the browser and load that new page in a new tab. What I want to do is the following: I want to have a file with all the sites that I want to load, and simply change that file from a remote computer if I want to add or remove sites. I also want to specify how long a page should be displayed. Then when I am done I simply upload my changes to the web server instead of having to go to the other computer and load a new tab. So I would have something like: [login to view URL] - 30 seconds [login to view URL] - 10 seconds [login to view URL] - 45 seconds etc etc Let me know if this is not clear enough, I can clarify the specifications. Thank you.
