Not able to configure burp with firefox - Received fatal alert: access_denied

Sunny | Last updated: Apr 30, 2019 08:09AM UTC

I am trying to setup my burp with firefox for the first time. Steps I followed: - Changed the proxy in Firefox to 127.0.0.1:8080 - Removed NO Proxy for "localhost, 127.0.0.1" - Imported cert.der to firefox certificates section. Trying to intercept request, getting following error in alert tab of burp: javax.net.ssl.SSLException: Received fatal alert: access_denied Received fatal alert: access_denied Please guide me here, what wrong I did. Burp Version - 1.7.36 Community Edition

Are you encountering this error on all HTTPS sites? Could you send us a screenshot of the certificate in the Firefox certificate settings? Have you tried using another browser?

I uninstalled everything (browser and burp), re-install all and follow the same steps. This time it worked. :)
