Can't search with Google using Firefox version 73.0
Updated to Firefox Version 73.0 yesterday (Feb. 13, 2020) and today can't do a Google search. Am running Windows 7 Pro 64 bit.
Additional System Details
- Shockwave Flash 32.0 r0
- User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:73.0) Gecko/20100101 Firefox/73.0
You mentioned there is a certificate error. Could you click the "Advanced" button on the error page and report back on the error code? Often looks like SEC_ERROR_SOMETHING.
