I see some comments recently about difficulty accessing certain websites with Firefox. Typically these comments revolve around the use of certain extensions. I have been using Firefox for more than a decade but I am close to giving-up on it. Starting a couple of versions ago I have daily have been unable to access various websites. At the same time I am able to access these same websites with Chrome. I am not using any extension in Firefox that I am not using in Chrome. What I find more strange is that my ability to access websites seems to vary with the time of day. Websites I can not access in the morning, I am usually able to access later in the day.
