This is caused by Ancestry using newrelic to host some files and this server is on a disconnect blocklist used by Firefox ETP and content blocking extensions. You can add an exception to disable ETP for your Ancestry website.

If you use extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) that can block content (Adblock Plus, NoScript, DuckDuckGo PE, Disconnect, Ghostery, Privacy Badger, uBlock Origin) always make sure such extensions do not block content.

• make sure your extensions and filters are updated to the latest version

Firefox shows a purple shield instead of a gray shield at the left end of the location/address bar in case Enhanced Tracking Protection is blocking content.

• click the shield icon for more detail and possibly disable the protection

You can check the Web Console for relevant-looking messages about blocked content.

Hello Cor-el, Thanks for the response and the suggestions. I have been systematically trying the various suggestions to overcome the issue(s). However, I have not been able to fix the problem. • I turned off the proxy settings (no difference) • I turned off the IPv6 (no difference) • DNS Prefetching (no difference) • Started Firefox in Troubleshooting mode (Turn off all extensions etc), restarted Program as well as restarted computer following TSM)- (no difference) • Added 'Ancestry.com' to exceptions (no difference) • Performance Settings: Turned off Hardware Acceleration (no difference)

- All changes were made one at a time. - After all changes, Firefox was restarted - When no difference was noted, the computer was also restarted.

For the most part, most all of the Ancestry site works. The only parts I continue to have problems with includes 1) Access to the Ancestry Internal Mail system 2) Access to any graphics via their internal 'Gallery section' (where graphics are stored for each item/person).

The issue appears strange that all other sections work fine, and only these two sections are problematic (I note where you highlight the use 'newrelic to host some files and this server is on a disconnect blocklist used'

Whilst I was able to add the Ancestry.com as an exception (Working through the Shield icon in the URL Bar) I did wonder if there were somewhere else to add Ancestry as an exception (could all be the same for all I know).

I included a pic of what I see after making the changes (yellow bar appears for the messages, not allowing access.

I wonder if I could tell Ancestry that there is the 'newrelic to host some files and this server is on a disconnect blocklist used' aspect. Just thought that I would ask first before just sharing that with Ancestry.

The access to Ancestry technical support appears exceptionally ignorant (and very hard to access), beyond frustrating. So apologies for continuing to seek some support to overcome the issues (of course Ancestry blame everything else).

Your assistance is very much appreciated. Regards Jim

This is caused by Ancestry using newrelic to host some of its files. The newrelic server is on the Disconnect blocklist used by Firefox ETP in strict mode and possibly used by content blocking extensions and this causes the problem. You can add an exception to disable ETP for your Ancestry website via "Settings -> Privacy & Security".
