1449175 - Toolbars menu in Customize mode won't open

Status: RESOLVED DUPLICATE of bug 1445795

(Firefox :: Untriaged, defect)

Description

[Home Olio]

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:59.0) Gecko/20100101 Firefox/59.0
Build ID: 20180316021607

Steps to reproduce:

I was creating a new profile for trouble-shooting purposes, and when I entered the Customize mode, I noticed that I cannot open the Toolbars menu that resides near the lower left-hand corner.

This behavior appeared in FF 59.0.1. It was not present in Firefox 59.0. The problem occurs in all profiles on my Ubuntu 16.04 machine, but it does not occur on Windows at all. I have created several test profiles, but to no avail.

I have religiously applied all software updates available to Ubuntu, but I have not installed any new software recently - definitely not between upgrading FF from 5.9 to 59.0.1. In an effort to solve the problem, I have even unistalled Firefox completely and reinstalled it, but the problem still occurs.


Actual results:

I cannot open the Toolbars menu that resides near the lower left-hand corner in Customize mode. 


Expected results:

I expect the toolbars menu to open up just like the other two menus in Customize mode do.
