Foxden runs multiple Web apps in one tab

Sites like Netvibes, My Yahoo, and iGoogle are great for organizing multiple feeds and widgets on a single page, but what about if you want to get your hands on full Web pages? New Firefox tool Foxden does just that, letting you set up a framed page that renders separate Web pages within the same space. This doesn't work on all sites, especially ones that like as much screen real estate as possible; but for some it's a handy way to consolidate pages you want to keep open without filling up your available tab space.

To set it up you simply pick which sites you want and how you want them laid out, either as rows or columns. You can also have it open up local files on your machine, like text or HTML files in case you have something like a to-do list that you keep on your desktop (in which case you may want to upgrade to something like Remember the Milk or Shifd in case of a hard drive disaster). Then, to call it up you simply select it from the tools menu, and it will open up as a new window, with all the sites you've added in the locations you've given them.

Actually setting up how you want it laid out isn't all that difficult, but it's not exactly a simple affair. You have to set it up with operators that define how many rows and columns you want, and which sites go in which boxes. You can also drag the dividers to resize how much space you want for each block, which the add-on remembers between browser sessions.

This extension probably isn't for everybody, but I dig the fact that it can very quickly be customized as a heads-up display for real Web pages, which if you've set up right (and have a big monitor) certainly beats having multiple browser windows opened up and painstakingly arranged.
