hello, could you go to the firefox menu ≡ > help ? > troubleshooting information, copy the contents of that page and paste them here into a reply on the forum? this might give us a clue what is going on...

I pasted the "Troubleshooting Info" here. Hope it helps. Let me know if you need anything else.

Thanks.

thank you - does an update of your intel driver help? https://downloadcenter.intel.com/download/25484/Intel-Grafik-Treiber-f-r-Windows-7-8-1-10-15-40-

I will double check the Intel driver version but updating the Intel driver to to the latest version was the first thing updated with Dell support when this message first appeared. The problem persisted. Unfortunately the only thing that has solved the issue is using a different browser ;-(.

I have this problem too, but it occurs repeatedly, sometimes within 10 or 15 seconds of each other, for as long as I use Firefox.
