Are all those page you cannot reach secure pages, by any chance? If so, you might want to check your firewall rules.

Let's see, the first link that you listed, Firefox gives me the dreaded "Unable to connect" message.

And using the second link, I can't access the Enum Process page because of the same "Unable to connect" to download the program.

Doesn't seem like it's my firewall.

Do a malware check with some malware scanning programs on the Windows computer.
You need to scan with all programs because each program detects different malware.
Make sure that you update each program to get the latest version of their databases before doing a scan.

You can also do a check for a rootkit infection with TDSSKiller.

The answer was to re-install Firefox. But now, I'm having another issue with 17.01.

Again, I am back here. I can't load my bank site again or get to the USPS.com web site. I get the "unable to connect" page. As you can see in the above post, I thought the matter had been fixed.

I have uninstalled and in-stalled 17 about 3 or 4 times now, and have even done a reset. Apparently the 'fix' lasted less than a week. Two days ago I could get to my bank site, now I can't. I have not installed anything since my 'fix'. I have not changed anything since my 'fix'.

I can no longer afford to waste time trying to make 17 work with my computer. It has proven to be totally unstable.

Where can I get a downgrade?

A possible cause is security software (firewall,anti-virus) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.

Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.
