First of all: Many thanks for writing an maintaining this essential browser extension (***** when working)!

Apparently some changes were required for FF49+, that have been made in version 1.3. Unfortunately, this version does still not work under Ubuntu 16.4 LTS (Xenial) because it requires Qt 5.7, but Ubuntu Xenial uses only Qt 5.5 (see ldd output below). This is bad, since Xenial is the current LTS (long term support) version of Ubuntu and they are not likely to change the Qt version during its lifecycle of five years.
So, PLEASE make this extension work with Qt 5.5, or all Ubuntu LTS users are locked out until at least 2018.

PS: Sorry, couldn't file this report via email since the captcha on the author's webpage just did'nt show.
