Make sure all your drivers are up to date and are properly working, this may also be the result of a hardware problem, or a Windows issue itself. Can you give me a summary of the Blue Screen error? It may contain useful technical information.

Hi. All drivers are up to date. The crashes happens while I am surfing with Firefox. Only then! Not every time at the same page, but as I remember always when I browse through e.g. catalogue pages. Last time my PC crashed, I was browsing through the picture of an advertisement on ebay to rent an office. https://www.ebay-kleinanzeigen.de/s-anzeige/raum-in-einer-belleetage-jugendstilvilla-zur-untermiete/797174932-277-9420 My PC created a dump (C:\Windows\Minidump\...). I cannot attach it to this answer, because it allows only picture. How can I send it to you? Matthias

You can attach a picture to your reply.

Hi MKll. Sorry, but your answers and questions are annoying. Are you panting for SUMO badges? I am a great fan of Mozilla and its philosophy. But you are going to destroy it. I do not have a picture. Other type of files are not accepted from the support site. As I wrote, I have a dump file, which was created by Windows during the crash. I like to help Mozilla to improve Firefox. If there is a possibility to send the file to you and if you are interested to receive and inspect it, please tell me how to do it. Kind regards Matthias
