Safelinking shows blank page with iMac/Firefox browser?

Hi,
I have been using this forum for a number of years now and the safelinking always worked fine until I recently got a new iMac and updated my Firefox browser
Now when i right click and open in a new tab it shows “Secure your link” at the top of the tab but the page is always blank, I have tried many safelinking links but always the same.
Any help much appreciated as this is really bugging me
Using Firefox 38.0.5
OSX Yosemite 10.10.3
thanks in advance Chris
