Firefox is unable to preview video and flash object elements in the editable IFRAME / DIV elements. For that reason RadEditor is displaying an images over the hidden object tag and you can see in the real-time html module in Design mode that the editor is inserting an img tag in the param tag of the object tag:
<img isflash="true" src="/mar26/WebResource.axd?d=VKgfCOMGbNfFHpaQ2fagQwx54iDXBFZvJ7fIi4SHX7kJQaESHnWBw0ciKR3EmQ4gyVj3mPF0yY8UbGwj-HF14xc1L6Up4UM7hu5wOZEGJyM1&t=633761549161885913" ...
This tag is removed when switching to Html mode or submitting the content.
If this tag is not removed for some reason when the user is not in design mode then this is a bug. I tried to reproduce this behavior but to no avail. Are you able to reproduce it using the Save In Database
example of RadEditor? If yes, could you please open a support ticket and send a video demonstrating the issue? You can use SnagIt
for example to
capture the video.
If you are unable to reproduce the problem, please send a sample working project along with a video or screenshots demonstrating how to reproduce it on our side.
Once we are able to recreate the problem locally, we will do our best to provide a solution.
