Since a few weeks ago, I have had problems with Firefox "hanging" when trying to access Google sites; this includes typing something into the search window on the address bar. Sometimes, changing the URL from "google.com" to "google.co.uk" or vice versa causes the site to load, but not always, and with Google maps, sometimes the site partially loads - e.g. satellite view and some icons missing. I have never seen this on Firefox with non-Google sites, nor on Chrome/Edge with Google sites. I have tried the other suggestions here, such as disabling anti-virus, clearing proxy (not that I use one anyway) etc, and clearing the DNS and HTTP caches, to no avail. I have no relevant extensions. What is particularly strange is that when a URL is not loading, if I open Chrome and type in that same URL, it will load immediately there and also immediately in Firefox (sometimes needing a refresh). I have seen other reports online of similar issues in recent weeks from other users, which makes me feel that it may be related to a recent Firefox update.
