Github website "Clone or Download" button not working on firefox

Question

I am using firefox version 49.0.1. Now for every github repository the button "Clone or download" doesn't work.

I checked the console it shows this

• The first two lines are printed in console whenever I access any page of github.com and the 3rd line when I click the green "clone or download" button.

• Also the small door like option by which we logout of github doesn't work.

(Why old version of firefox? ) Because it's provide a feature (small UI related thing which bugs me in latest version)

It was working few days ago.

Solved

Github resolved it on May 9-10 2017.

Answer 1

Here is a workaround:

1. go to about:config
2. find the entry security.csp.enable
3. double-click that row to set the Value to false

Obviously, this might impact safety in horrible ways, but at least I can continue working.
