like fellow reviewer "number6" said on September 3, 2010, there is a bug with addon BarTab. With BarTab installed, CopyAllURLs can NOT read the names of UNLOADED tabs correctly. It reads the URL as name and outputs 2 lines of the same URL, like "number6" mentioned in his/her review.
There is also a bug with CopyAllURLs' function "Copy Tab History". If you do NOT ENABLE this function, then the "$tab" markup will NOT WORK. It will show "undefined" as the tab number.
I hope these 2 bugs can be fixed then the addon will be perfect.
