Recent Changes to zoom.it, Firefox, or Silverlight causing issues?

A colleague of mine discovered this morning that, on his Mac and in the Firefox browser, all our nice, clean zoom.it displays have been replaced with warnings saying "this plug-in is vulnerable and should be updated." Could it be a Silverlight issue? I really have no idea. But he said on 100% of the pages on our website which display zoom.it imagery, this same error is being displayed. Users can click through/past it to see the images! But still an issue that doesn't look/work as good as it did a couple days ago.

Any ideas? Thanks.

From what you describe, this sounds like a change in Firefox. There have been no changes to Silverlight for the past year. It would be prudent to make sure you're running the latest version of Silverlight. I haven't fired up a Mac for quite a while, but you should be able to verify the version you have and download the latest at http://www.microsoft.com/getsilverlight. I will pull out my Mac and check out the exact procedure on this later today.

An immediate workaround is to simply disable Silverlight in Firefox. I haven't used Firefox in a long time, but I'm sure there is a settings dialog where you can control the various plug-ins. Disable Silverlight and zoom.it will continue to work (albeit with a bit slower performance) using JavaScript.

I'll try to repro your problem (hopefully later today) and see if I can provide any additional ideas. You may also want to ping the folks at Mozilla about this warning message.

Thanks Bill!

My colleague who works on a Mac (using Firefox) updated his version of Silverlight a few minutes ago, and that seemed to resolve the issue for him. Strange thing is (if Silverlight hasn't changed in the past year) he's been running Firefox on the Mac for years...and only this morning received that error. So it must be something with Firefox that isn't "playing nice" with Silverlight at the moment...or at least not as nice as it was as a day or two ago.
