Bug#836781: firefox-esr: Regression: Pinterest "Pin It" Button does not show up

[Lisette]

Package: firefox-esr
Version: 45.3.0esr-1~deb8u1
Severity: normal

This extension: https://about.pinterest.com/en/browser-button used to add a
toolbar button.  When I upgraded the firefox (used to use iceweasel) package at
some point, it stopped showing the button.  Does not show under the "customize"
menu or anywhere else I look.  Some other extensions (Amazon Assistant) behave
this way also.  Some (Disconnect, HTTPS Everywhere) show their toolbar buttons
without issue.

Removing and re-adding the extension does not help.  Disabling other extensions
does not help.

Output in console when running firefox with extension enabled:

(process:4620): GLib-CRITICAL **: g_path_get_basename: assertion 'file_name !=
NULL' failed
