Hamburger menu (..and some other dropdown lists) are not visible.
I can click options from those menus, but I don't see what option I'm clicking.

Recently another poster using Firefox had invisible menus while using KDE on Ubuntu 16.04.1 and was able to fix it.

It that OK while running in the Firefox SafeMode?
If not, please provide a screenshot /s of what you have, and maybe what;s not happening or not working.
See this support article. How do I create a screenshot of my problem? It is best to use a compressed image type like PNG or JPG to save the screenshot and make sure that you do not exceed a maximum file size of 1 MB.
Then use the Browse .... button below the Post a Reply text box to upload the screenshot.
(Screenshot attached) The menu exists there, because I can click and run some random option, but it's invisible.
Running Firefox in safe mode nor "Refresh Firefox", does not solve the problem.
I think problem has started after uninstalling "Addblock plus" add-on or when trying to install "uBlock Origin" (which has failed)
I have Firefox version: 61.0.1+build1-0ubuntu0.16.04.1 on: Linux, Kubuntu 16.04 (with all upgrades)
