What does SEC_ERROR_BAD_SIGNATURE mean. It blocks Facebook and most sites

You can check the connection settings.
- Options/Preferences -> General -> Network: Connection -> Settings
If you do not need to use a proxy to connect to internet then try to select "No Proxy" if "Use the system proxy settings" or one of the others do not work properly.

Hello,
Many site issues can be caused by corrupt cookies or cache. In order to try to fix these problems, the first step is to clear both cookies and the cache. Note: This will temporarily log you out of all sites you're logged in to. To clear cache and cookies do the following:
- (Firefox 57 and above) Click the Library button
and choose History.
(Click the menu buttonand choose History in older Firefox versions.)
- In the History menu, choose "Clear Recent History...".
- Under "Time range to clear", select "Everything".
- Now, click the arrow next to Details to toggle the Details list active.
- From the details list, check Cache and Cookies and uncheck everything else.
- Now click the "Clear Now" button.
Further information can be found in the Delete browsing, search and download history on Firefox article.
Did this fix your problems? Please report back to us!

An error occurred during a connection to www.facebook.com. Peer's certificate has an invalid signature. Error code: SEC_ERROR_BAD_SIGNATURE
The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. Please contact the web site owners to inform them of this problem.
Ha Ha Google or Facebook!!
There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connections and send their own certificate.
