Make sure you are not blocking content.

Start Firefox in Safe Mode {web link}

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

Many site issues can be caused by corrupt cookies or cache.

Warning ! ! This will log you out of sites you're logged in to. You may also lose any settings for that website.

Why do you think a cookie could cause a non https connection? This occurs when starting up as well while already using FF actively.

When I go to maps.google.com

Do you mean:

• http://maps.google.com/ or
• https://maps.google.com/

Same problem for both? Differences?

I am referring to https as most sites are only https and maps.google.com does not support http. My screen capture shows that whenI go to https://maps.google.com the screen then pauses. If I try http://maps.google.com it redirects to https. This issue occurs occasionally for several sites.

Remove History For One Site {web link}

Open the History Manager <Control> (Mac=<Command>) <Shift> H. In the search bar, enter the name of the site. Right-click on one of the listings and select Forget About This Site. This should remove all information, including any site settings

My FF is configured to never remember history so no value is present.

I don't see the attachment for that, but it sounds like you might be blocking redirects. Here's what I see:

• I click https://maps.google.com/ => server replies with a 302 redirect to https://maps.google.com/maps
• Firefox loads https://maps.google.com/maps => server replies with a 302 redirect to https://www.google.com/maps
• Firefox loads https://www.google.com/maps

If you are getting a blank page for the second or third steps, please make sure the redirect block is turned off:

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button accepting the risk.

(2) In the search box in the page, type or paste access and pause while the list is filtered

(3) If the accessibility.blockautorefresh preference has a value of true, double-click it to restore the default value of false

The default value of false is already set.
