Description (last modified by trev)


Adblock Plus
Firefox 43

How to reproduce

  1. Click ABP icon and choose Filter preferences.
  2. Wait a bit and close the window again.

Observed behaviour

"TypeError: this.treeElement is null" exception shows up in Browser Console, thrown by filters-filterview.js line 668. There are no side-effects it seems.

Expected behaviour

No error messages.


It seems that Firefox calls nsITreeView.setTree() with null parameter when the window is closed, this behavior must be new.
