We still use some Dell 13g servers equipped with idrac 8. When I'm trying to launch the virtual Console the window opens up but nothing shows. This used to work fine in previous versions of Firefox. I can't tell from which version it stopped but it's not long ago. Also idrac 9 console works fine in Firefox When trying to open console idrac 8 in Chrome it works fine Any idea what could be causing it? Any config switch to tweak?

My computer was compromised And as a result I had to repair and re install my Microsoft operating system windows 10 pro. That procedure wiped out my Firefox browser and now I have no record. Is there a backup that the browser keeps on a cloud.
