hi, you should never set an exception for a well-known site like google, but address the source of the problem - likely something on your system/network is intercepting encrypted connections.

first please make sure that the date, time & timezone are set correctly set correctly on your system. if this doesn't solve the issue (or it is already set properly), a solution depends on the individual circumstances:

• what is the error code shown when you click on advanced on that error page?
• please also give us more information about the error by clicking on the error code, copying the text to the clipboard and then pasting it here into a reply in the forum.

thank you!

my system time zone and every thing is set correctly, and the same google is working fine from chrome so i hope there is no issue with network as well.Please check screen shot related to error code

Thanks

please copy/paste the error in text form. (transcribing the information from the picture would be a hassle)

Peer’s Certificate issuer is not recognized.

XXXXXXXXXXXXXXXXXXXX certificate from my company

thanks, the certificate seems to come from

Issuer 	CN = <redacted>
Subject 	CN = WEBGATEWAY

... which is obviously not the genuine certificate authority that google is using. are you within a corporate environment?

yes, so how to add this certificate

it's certificate given by corporate company

can you try to import it similar to how jscher has described it here?: https://support.mozilla.org/en-US/questions/1068675#answer-745280
