[BUG] 30-sslsniff unable to capture latest firefox(NSS) packet

**Describe the bug**
When I try to capture the NSS on my pc. It doesn't work. Also the --extra-lib doesn't work
As mentioned in the documentation:
`./sslsniff --extra-lib openssl:/path/libssl.so.1.1`

**To Reproduce**
sudo ./sslsniff --extra-lib nss:/opt/firefox/libnspr4.so

**Expected behavior**
It should add additinal libraries.
**Screenshots**
```
Also I want to capture the traffic for firefox. How to achieve this?
