Is there a way to get some sort of indication which tabs were spawned from a certain window.
sort of like this Firefox Addon
or like the way the tabs are coloured in the latest IE
You can give a try to TooManyTabs for chrome. It shows the opened tab in the thumbnail view. Also like FF their is the same addon for Chrome is available Tree Style Tab which is in beta state so many bugs will be. You can also give a try to IE Tab Multi (Enhance) which gives the experience of IE on Chrome.
Sorry for little details, have not tested them properly yet. for now i use first one.
Will update after fiddling around with them
