Hi, perhaps one of your installed extensions is a known problem.

Could you open the About Debugging page in Firefox: type or paste about:debugging in the address bar and press Enter to load it.

In the left column, click This Firefox. The page should list all the currently enabled extensions. If you use Find (Ctrl+f) to look for part of that GUID, such as 246C, can you link it to one of your currently enabled extensions?

If it doesn't come up that way, I can suggest other ways to research it.

On the Add-ons page, consider disabling or removing that extension. Please make a note of its name in case it needs to be reported as something Mozilla should block.

Thank you for the quick reply! I followed your instructions Since malwarebytes has quarantined this it is not listed in my extensions.
