Unable to load UPS and FedEx websites all of a sudden
Suddenly I am unable to load UPS.com and FedEx.com. And a couple other websites. Other browsers have no problems. Tried all the usual stuff with cookies, cache, proxy, IPV6, etc., problem is limited just to Firefox. When I type in the link it acts like the server is not responding. Whatever the problem is it's strictly with Firefox. Very frustrating!

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.

Didn't work. The one webpage is an e-commerce site and doesn't load properly in Firefox. Some other websites give the below error. I just noticed I have to update MAC OS and reboot. I will do that and see what happens. Thank you!
The connection was reset
The connection to the server was reset while the page was loading.
The site could be temporarily unavailable or too busy. Try again in a few moments. If you are unable to load any pages, check your computer’s network connection. If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.
There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connection certificates and send their own.
