Edge not working for you in Windows 10 (1809)? Try Fiddler
If you've upgraded to the latest version of Windows 10 (1809) and are having problems browsing the web, try running Fiddler. Having this sat between the interweb and Edge seemed to kick it straight back into life for me.
It looks like, for me, this is caused by Sophos Endpoint Protection - so if you can turn this off, that's well worth a go too!
