We work with generating reports as a HTM format which we then open in Firefox to export as a PDF. We choose Firefox to do this as it neatly splits up the pages without cutting content in half. However, after the 126 update, images that are part of the HTM file no longer loads, leaving a blank void.

Does anyone know why this is or whether they know how to fix it? It is a result of plugging a vulnerability in the browser?

Your help is very much appreciated.

Thank you.

Hi there, I hope you are doing well.

Firefox 126 added stricter security for local files, which can prevent images from loading in HTML reports. To resolve this, you can adjust `privacy.file_unique_origin` in `about:config` to `false` or use relative paths for images. Another option is to use a local web server to bypass these restrictions.

Thanks, Mike Taku.
