Hi,

I've installed 37.0.1 - clean install, and when I try to get to any link, I get the 'This Connection Untrusted' error - for every site I have tried. Including Mozilla and google sites.

Is this a 37.0.1 bug?

Running 37.0.1 on Macbook Pro with OSX Yosemite installed.

Thank you very much.

Turns out it was Avast Security on my Mac, once disabled Firefox worked flawlessly. Had to uninstall both, and reinstall Firefox first, Avast second in order for Firefox to accept the Avast cert.

Two common reasons for this are:

(1) Problem with the system clock: date, time, or time zone differs substantially from the rest of the internet

(2) Firefox not set up to work with your security software that filters your web traffic

In order to filter secure traffic, your security software needs to present "fake" certificates to Firefox so it can be the "man in the middle" and see everything sent to and from the site. Firefox distrusts the fake certificates until instructed otherwise.

Do you use any software with that kind of feature? On Windows, products with that feature include avast! 2015, Bitdefender, ESET, and Kaspersky.

A less common problem is malware performing a "man in the middle" attack.
