I too am having problems with Tabs Outliner crashing due to memory issues. It happens about once every other day. I do typically have a large number of tabs open which is one of the driving reasons I use the extension. It would be keen if there was an automated way to clean things up as this thread suggests OR either some form of memory optimization (assuming this isn't just a leak) or a way to increase the limits Chrome allows an extension before it will crash the extension for using too much (I have plenty of RAM in general).
