Today I installed Firefox Quantum on my Mac running High Sierra. It will not connect to any mozilla domain, including subdomains such as addons. Mozilla domains work fine on Chrome and Safari; I made sure proxy settings were sane (off).

I have tried completely removing all traces of Firefox and reinstalling to ensure any weird preferences are wiped out. This did not change the behavior.

I've attached a screenshot of the web console when trying to load addons.mozilla.org. Unfortunately, I cannot post from Firefox since it won't connect to support.mozilla.org either.

Hi, if running any of these it could be them : Avast/AVG, Kaspersky, BitDefender and ESET

Can try this : Refresh but Note that this does more than uninstalling and re-installing does. Normal uninstalling does not remove some preferences which may have become corrupt. Please Refresh but do this 1st:

then

Or Dump Firefox and get a Full Version from here :

Hi,

Refreshing does not change anything. It still refuses to load mozilla.org. I do not have any endpoint protection running.

That was my thought as well. Malwarebytes is showing clean, however. Not that that really proves anything, but there it is.
