Great, but one thing Rated 4 out of 5 stars
This extension is great, and it is a valuable tool when I am developing websites, not to mention updating my computer with still only one browser window. However, there appears to be a large memory leak somewhere. With the extension installed, my Firefox took twice as long to start, and would begin to get slow after a couple of hours open. After uninstalling IETab and disabling satellite imagery in ForecastFox, it starts up as fast as IE and can run for hours on end with no trouble. I'll try re-enabling satellite imagery in ForecastFox to see if the problem returns. I'll post back here with the results.This review is for a previous version of the add-on (184.108.40.20670528).
