Extender Not Displaying Plugins / Can't Refresh

Steve Feb 08, 2019 10:24PM UTC

I am behind a corporate proxy environment using Ubuntu. Using the corporate proxy settings I am able to use Firefox to view websites as expected so Burpsuite should be able to display the BApp Store list under the Extender tab. The list is empty and the Refresh button is grayed out.

What do you recommend? Thanks

This is normally caused by your upstream proxy being a SSL-breaking proxy, causing Burp’s certificate verification to fail.

One workaround is to ask the proxy admin to whitelist the portswigger.net domain so SSL breaking is disabled.

Otherwise, you’ll need to install the upstream proxy certificate into the Java key store. There’s some information here:
