Hi @alexanderdevm,

I'm not able to reproduce this: I downloaded Firefox, opened the local pptxgenjs-demo.html page, clicked the Basic Slide Demo button and a PowerPoint was opened in Keynote.

Do you see any output in the Console that would indicate the issue?

After upgrading firefox to the latest version 53 on my first Mac, the issue disappeared, and i was able to reproduce the issue on older version of Firefox on different Mac.

• First Mac,, Mac sierra 10.12.4, Firefox 53.0
• Second Mac, Mac sierra 10.12.4 , Firefox 48.0.4

I have also tried local pptxgenjs-demo.html, and the page on your demo portal.

So it looks like unless your of Firefox 53 Mac, you will run into this issue.

I have noticed this on Firefox for windows version 44 and 46. No errors on the console but when I started to look through the save procedure I noticed the blob URL would begin with blob:null/. Could that be the issue?

As soon as I upgraded Firefox, issue disappeared. Unfortunately my client has either Firefox 46 or IE11. IE11 works for PptxGenJS but my requirements are to convert a d3 svg into a png and then place into a powerpoint file which does not work in IE11.

Hi @alexanderdevm @rwhitmore90,

Thanks for reporting this.

It looks like the element is being removed before Firefox can grab it, as seen in this StackOverflow answer.

I've added a delay before removing the element which should fix the issue.

Please try the using the latest code and let me know how it goes.
