I am not too sure if I am posting in the right category however I have created just a standard Facebook Like and Share button using the Facebook tool, ticking or unticking the correct boxes etc and then getting the code, below.
It works fine on Chrome, Safari, Opera, IE and Edge but does not show up at all on FireFox.
Thanks for that info so far… I am on the latest version of FireFox, I believe, 57.0.4 (64-bit) and running 64 bit Windows 10 which should also be the latest version.
The code is running on my server and, as I said, works on every other browser.
I have it imbedded into my website and stand alone in the above sample file.
I am not too sure what this additional HTML file is about.
This is a weird issue as it is just the standard Facebook code and you would think Facebook would supply code that works.
