Hi!

I want to dump/debug http traffic with mitm proxy: https://github.com/ganskef/LittleProxy-mitm . This proxy generates it's own root certificate which i manually imported to Firefox from about:preferences#privacy > View Certificates > Authorities > Import. I verified that cert shows up after importing it. But I get errors despite of that:

Secure Connection Failed

An error occurred during a connection to www.youtube.com. Peer’s certificate has an invalid signature.

Error code: SEC_ERROR_BAD_SIGNATURE

Is there a way to bypass it?

It turned out it was my fault. I took wrong cer from wrong place. With correct cert this proxy works fine and firefox is happy. Also it seems to be faster than mitmproxy that was written in python in case you need to performance.
