I got 59.0.2 (64-bit) installed. And I tried to download the AdBlock Plus and any others, all gave me “connection failure”. My connection is working fine. Please help. Thanks!

I have the same problem. I tried to create a permission in about:config, but it did not work.
All add-ons letters/links are in black color. They should be in multiple colors indicate the link is activate/good. I think.
Can you share a screenshot of what you’re seeing? Do you have any add-ons installed?
Hi Jorgev,
I have only McAfee addon and it got disable.
I tried to go https://adblockplus.org/ to download it. I got SEC_ERROR_UNKNOWN_ISSUER error
When I used the Chrome to download the extension from https://adblockplus.org/. It worked fine.
Thanks,
Sang
Today without using VPN, I am still able download the add-ons. Thanks!
