In thunderbird 3, I can open new tabs if I middle-click, but the behaviour I want is for left-click to open a new tab if there is not already a folder open for a given tab; or to switch to the tab displaying that folder if there is.
Is there a configuration setting or addon which will make thunderbird behave like that?

@Nathan.Eilisha Shiraini I hope I have addressed this concern – wsmwk – 2018-08-28T12:41:54.503
