Getting connection not secure error trying to access MyEBay in Firefox

[postingid7659]

Normally use Firefox to access eBay, but now it won't show the pages to me, I get this instead:

Your connection is not secure

The owner of invoice.ebay.com has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website.

I tried clearing the cookies out and so on and reopening it, no help. 

Works fine on Internet Explorer and I got here in Chrome.

That's odd, since I am using Firefox as well, and I am not getting that message. It was probably a temporary, say, error.

It appears to be a problem on my end, I just tried a different site and got the same error.

Just to make sure, could you share the link where it gives you that message?

It's odd indeed. I am using Firefox, too, however,  on my part it indicates that it is a secure connection.
I have included some screenshots.

I searched a bit more and it seems that others are having a similar issue with other websites using Firefox while having avast as their antivirus.
This link from mozilla firefox forum  may help: https://support.mozilla.org/en-US/questions/1199762

So, check whether there is  interference from the antivirus, but also check whether an add-on/exntesion of Firefox is interfering, too. Perhaps a program, such the antivirus, or an add-on, got recently updated and started malfunctioning.

Hope this will help.
