Sorry, after I downgraded to older Firefox ESR 68 releases, I upgraded to Firefox ESR 78 to see what it did. 68 just displayed a blank page while 78 displayed the error that I posted. I reviewed the web console as part of my troubleshooting and there were definitely third party cookies trying to load in the frame which we have rejected since 2019. The vendor who supports the app told me that they reject all cookies on their PCs and they don’t have any issues using their own tool internally. So they insisted it could not be a cookie issue and silly me listened to them when all evidence pointed to cookies. I am suspecting that the site that is opened in the frame must have updated their web site/server. I whitelisted the origin and this resolved the issue, but I am still scratching my head at why it happened out of the blue.
Kudos to the person who added the dialog in Firefox 78 since it helps to point you towards the cause for those who still have not discovered the wonders of the Web Console since it came be a bit terse to read, but generally points you in the right direction. BTW, I did turn off all tracking protection using the GUI and clicked on the option to reload all tabs, but this did not resolve the issue during troubleshooting. I had to close Firefox and relaunch in order to get the site to load before I put the third party cookies on the exception list.

That error message you are seeing doesn't exist in Firefox 68. Can you verify the version? That change was made in this bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1461195<https://urldefense.proofpoint.com/v2/url?u=https-3A__bugzilla.mozilla.org_show-5Fbug.cgi-3Fid-3D1461195&d=DwMFaQ&c=2WwxlqHD_9GeHFEUsOHZXg&r=a0pF-r4VjZCyzB4zxbRDcONPyw-KRRoDiBPd4lDRky8&m=0xCycvWizUMXoArAiUoI5nw-x6ZJj2LpLm_am-kriH4&s=s4QemWn3j8U63Nfrcb9Gs1LQiaAbP3kCLsw1Tt83Tp4&e=> and is only in Firefox 78 and later. But previously, the page would still have not loaded, you would have just not seen the option to open the site in a new window. Can you also turn off tracking protection and see if that's causing it?

This feels like something got confused with the site's content security policy or the x-frame-options headers, making Firefox unable to display the embedded content. Opening the web console (ctrl-shift-k) and loading the page should log something about the content failing to load, or the network monitor (ctrl-shift-e) might show the request for the embedded content being rejected, and one or both of those should give a hint of what's really happening.

I have an internal application that interfaces with a third-party vendor inside what I assume is a frame that has not been upgraded or patched since May (it’s an appliance so we upgrade the appliance to get OS patches). All of the sudden the data that should display has stopped – the pages that have this data from a third party vendor are not used on a regular basis. I downgraded from Firefox ESR 68.10 to prior versions that I KNOW worked a few weeks ago and the behavior is the same. Firefox ESR 78.0.2 displays an error message where there is blank space which makes me suspect Mozilla has changed how Firefox ESR 68.x releases behave since nothing has changed with our policies.
