I'm using Firefox at the moment which works fine but Safari fails to load pages, sometimes just loading a partial amount of the page or just getting stuck trying to load stuff but failing. No error messages just a constant spinning icon in the tab telling me the page is loading (but isn't).
Reports from the web seem to infer I'm not the only one - I've reset Safari, restarted my Mac, even switched my WiFi off and then on again as reported by one 'fix' but nothing

So.... can anyone help?
