Have you ever found yourself browsing with Firefox, only to find that you have WAY too many tabs open? I found an extension to relieve the tabbed thought processes a bit.
Split Browser does just what it says – it lets you split the browser window in to several panes. A right-left pane works really well on widescreen monitors, but you can also do top-bottom splits and even split the splits (say that five times fast).
In my screenshot example, I have several Digg stories open in tabs on the left, and when a story sounds interesting, I drag the link to the right pane. That way, my Digg tabs stay organized and I don’t lose focus while reading an article.
