Use the x on the far-right side of that "Console" toolbar.

Hallo Ed-meister, that is exactly my problem, there is no X on the far right side of the "Console" toolbar. I just have "All" "Errors" "Warnings" "Messages" and "Clear" on the top row, "Code" followed by a long field and then "Evaluate" on the next row, followed by rows of errors. There is no X to be seen anywhere

The close X might be faint and not easily visible. There should also be an icon to have the Web Developer tools in a separate window that you should be able to close via the close X on the title bar or Ctrl+W

Can you attach a screenshot?

Use a compressed image type like PNG or JPG to save the screenshot.

Hi Cor-el, I couldn't find either of your suggestions. I have attached a screenshot. Thanks

That is the classic error console and not the Browser Console that current Firefox releases have as part of the developer tools.

Are you using an extension that adds this version or the error console?

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.

• Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
• Do NOT click the Reset button on the Safe Mode start window

Hi Cor-el, thanks for your help. It was an Add-On called FEBE Version 8.0.4 which installs with DEBUG Mode turned on which causes the console to be displayed. Am back where I want to be. Many thanks for your help and patience. Kind regards, The_Boojum
