I have no idea what is going on, I have used Firefox Browser for several years with little issue, lately I have been getting the error: SEC_ERROR_BAD_SIGNATURE even on secure sites. It got to where Firefox v54 became unusable, even with the cookies and cache memory cleaned out. So I switched to Chrome, and for a couple of days, it worked fine, but now I am getting the error ERR_NETWORK_CHANGED on Chrome. I am running Windows 10, 64 bit, version 1703. BitDefender 2017 AV, and MalwareBytes. Acer Aspire E5-574G, i7-6500U, 8 RAM Any ideas what may be going on? Thanks
