I have been trying to access Coursera on Firefox browser but I am getting a unsecure connection whenever I open Coursera. ( A yellow hazard icon on the lock icon). I opened Coursera on Firefox on two different devices but both have the same problem. I do not encounter this problem on Google Chrome.


I would appreciate some help as I need to use Coursera. Thanks!

Does the problem persist if you clear Firefox's web cache and then reload the page? See:

How to clear the Firefox cache

Note: just clear the web cache, not all the cookies and site data.

You can check the Web Console (Tools -> Web Developer) for messages about blocked content and about the presence of mixed or unsafe content.

You can check the Network Monitor to see if content is blocked or otherwise fails to load.

If necessary use "Ctrl+F5" or "Ctrl+Shift+R" (Mac: Command+Shift+R) to reload the page and bypass the cache to generate a fresh log.
