Bullet Points, Add Media & Favicon not showing in firefox

Hi, Firstly, nice theme! Unfortunately, have been having a few teething problems and have been asked to start this topic to have it resolved. I have installed the wordpress, base theme and then the vcomposer with modern demo. Created a homepage and added the modern demo on that page. The bullet points of the demo show fine, but when I add a new text box field, and add bullet points, although the html code is there, it does not display them. Likewise, in the text box if I click Add Media and select a photo, it won't enter it. I have also been having an issue with the favicon in Firefox, I've cleared cache but my favicon, when I add the page as a bookmark doesn't show up in Firefox.. it does in Chrome. I did have some issues with my logo in the footer, but it seems to be working now after using the modern demo instead of the old theme. But may be connected to above same issues. If you could look into this, it would be great. I sent over some screen captures via Facebook. Cheers Marco N. Expat College
