Mozilla Firefox Security Warning

Posted on 2010-11-12
Last Modified: 2012-05-10
I have a secure website developed using ASP.NET that works fine in all browsers I have tested except Mozilla.  The problem is that Mozilla reports that some items on the page are not encrypted and as far as I can tell everything is encrypted and passed from the web server.

If I disbale JavaScript in my Mozilla browser the problem goes away but I need JS for the site to function.  Other users have reported this same issue whereas others do not get this warning...

All the JavaScript code is embedded in the HTML page within a script tag.

Make sure ALL content, scripts images etc. are being served from the secure server. You will get this message if, for example, you are referencing an image from a non-secure server:

<img src="" />

Hope this helps,

Only two images and both are relative references to th eserver and Mozilla reports both as coming from an HTTPS link.

All scripts are embedded within the HTML page so must be coming via the HTTPS page load?

Sorry, also meant to say that I have now tested thi son another PC that I have and it works fine with no errors so looks like is is somhow a client specific issue.  Both PC's are running the same OS and SP, both have a clean default install of Firefox and all settings as far as I can tell are the same - so a real mystery!

I'm not getting any error message here on any browser, but there are a lot of (x)html errors. It looks like it has been cut and pasted from Microsoft Word which adds a lot of useless tags.

Try cleaning up the code and see if this helps:

Remove '<?xml namespace="" ns="urn:schemas-microsoft-com:office:office" prefix="o" ?>'

Remove all '<o:p>' and '</o:p>' tags

The document is declared as xhtml, so all tags must be lower case, ie. change all <SPAN> to <span>, all <FONT> to <font> etc.
