Hi,

When I open firefox (note: I got firefox version 28.0 and Karspersky security 2014) I get a black screen covering the whole firefox window and it looks more lika a big command prompt window, in firefox. What is it?

Regards

Jean

Huh, that's a new one...

Can you try Firefox in Safe Mode to see if the problem goes away. I'm thinking it's an extension.

  • Run firefox.exe -safe-mode in the search bar on the Start Menu. (Make sure Firefox is closed)

Have you added any new extensions recently around the time this started happening? Your system details shows the following:

  • Adobe Acrobat - Create PDF 1.2 (web2pdfextension@web2pdf.adobedotcom)
  • Anti-Banner 14.0.0.4917 (anti_banner@kaspersky.com)
  • Dangerous Websites Blocker 14.0.0.4917 (content_blocker@kaspersky.com)
  • Kaspersky URL Advisor 14.0.0.4917 (url_advisor@kaspersky.com)
  • Troubleshooter 1.1a (troubleshooter@mozilla.org) This is default so this isn't the problem.
  • Virtual Keyboard 14.0.0.4917 (virtual_keyboard@kaspersky.com)

Can you take a screenshot?

Here is the screenshot. Note: This problem doesn´t always occur . It has been gone for a few days, now it´s back. It flashes by very fast and then it goes to the startpage of firefox (which I have as the startpage) , so it was hard to make a screenshot of it. But I finally "caught" it.

Regards,

Jean

Hi Moses,

Yes, it worked! The problem disappeared when I started it in safe mode. I guess I have to remove one of the extensions, one by one to see which one is the culprit. :)

Thanks again for your help.

Regards, Jean

Great! I have some feeling that it's something Kaspersky related, of course the majority of your extensions are installed by Kaspersky. Y

Let me know how it goes!
