Description (last modified by trev)
Environment
Adblock Plus 2.7.0.4095-beta
Firefox 43
How to reproduce
- Click ABP icon and choose Filter preferences.
- 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.
Background
It seems that Firefox calls nsITreeView.setTree() with null parameter when the window is closed, this behavior must be new.
