If you need support from Yola please contact us via email@example.com or make use of our live chat service! We are working on a new approach to community-based support and during this transition period we are not adding any new threads to this forum. Many thanks to everyone who has participated over the years and we look forward to unveiling a new peer-to-peer support system soon!
Ed is right that this problem is specific to Firefox. It is most likely caused by the flash widgets on your page - however, this is our bug and we need to fix it.
One thing that would be useful is if you could open your site in the SynthaSite sitebuilder, click on the Help menu and then click "contact support". Fill in the form and send it to us. This will give us some additional information that could be useful in addressing the bug.
I apologize for the inconvenience and I hope we can resolve this problem!
