Second Google+ button invisible in Firefox

Question

We have Google+ buttons one of our website. They are showing fine in all browsers except Firefox. The button above the article works fine, but the button below is invisible in Firefox. Can't find why this is the case, does anyone have some ideas on how to fix this?

Answer 1

After inspecting the HTML once again I noticed someone added the script-tag that you need to insert for the Google Plus button twice. This is not as it should be and Firefox stops rendering Google Plus buttons after the second script-tag.

So I removed the duplicate script-tag and all browsers, including Firefox, are rendering the buttons fine now!
