posted 8 years agoIt's new web extensions API limitation in Firefox, tab object does not provide "openerTabId", which is present in any chromium browser. New tabs opened from a middle click, ctrl+link click, new tab button or even bookmark will not append to the tree, since new tab does not have any information which tab opened it.
In essence there is no parent/child information.
To somewhat mitigate lack of that, you must set "Append orphan tabs" to "treat as active's tab child" as you mentioned.
Firefox team is working on it and I hope they will not ignore this issue.
For this matter, you can join conversation at:

I know he has his hands full with other more important bugs, but you can beg Kris Maglione for a fix ;)
