Win7 on a desktop. When opening certain URLs in Firefox, a popup box appears in Spanish, appearing to ask if I want to set Explorer as the default browser. A NO response closes Firefox and opens a URL in Explorer, which is usually my Gmail email web window.

The error is consistent as it always happens when opening certain URL's, but not on certain other sites. I did a screen grab of the error message and saved it as a jpeg, but cannot seem to attach it through this web page link below. It can be emailed without problem.

Hello AlmostRetired,

To attach the saved screenshot file to this forum post, click the Browse... button below the Post your reply box and locate the image. This will help us to visualize the problem, as what you have described does not look like common Firefox behavior.

Thank you!
