Firefox Community Forum

I subscribe to my city's newsletter. It gives quick links "click here" to register for a class, "click here" for information about an upcoming parade. I used to be able to click and get it. Now it tells me It can't find the site OR I might be connected but behind a firewall. There are too many options and too many terms, I don't know what to do, I just want to click links from my city newsletter, and get taken to them. Help???

Hmm. We’re having trouble finding that site.

We can’t connect to the server at vu4mbwlab.cc.rs6.net.

If you entered the right address, you can:

   Try again later
   Check your network connection
   Check that Firefox has permission to access the web (you might be connected but behind a firewall)

I've just finished building a new machine and have installed Firefox:

ESR 45.9.0 (OS/2 port)

I want to sync it with my other machines but, when I try to log in, I get:

Blocked By Content Security Policy This page has a content security policy that prevents it from being loaded in this way. Firefox prevented this page from loading in this way because the page has a content security policy that disallows it.

I know the account is good, I'm logged onto it right now from another (Windows) machine; and I was able to log on and sync from the OS/2 machine this one replaced.

So what can I do to fix this?

Thanks.
