I will be updating both CoLT and Googlebar Lite in the coming days, adding support for the new Firefox 3.6 builds. I'm also thinking about making a change for Googlebar Lite. Today, when you enter and exit private browsing mode, the Googlebar Lite search box does not clear itself (as other controls do). I'm going to look at adding this capability, probably only for the "exiting private browsing" case. If you have any suggestions or comments on this feature, feel free to comment below.
