Someone else began a thread about this issue, but it went sideways as to the description of the issue so I thought I'd start again... Since the new Insider build, if you create a shortcut to a web address in Windows (e.g. right-click on desktop, new, shortcut, www.firefox.com) ..when you click on the shortcut, Firefox browser window opens the "locally saved" copy of the web page in the browser window instead of displaying the website itself. -- If I change the default browser over to Internet Explorer, the same shortcut created above works normally to visit the shortcut's website. -- if I change the default browser back to Firefox, same undesired behavior. ATTACHED is a graphic which demonstrates what I describe. The Address bar should say "htto://www.firefox.com" and not refer to some object on my local "C" drive. Obviously this may be a windows problem in how it communicates the request to firefox..
