Client certificate does not seem to work with the newest burp, but one earlier version it does.

Yesterday I had version v2.0.07beta and I put in user options, ssl a client certificate with password ( pfx with p12 extension name ). I was able to test using this setup, this morning I updated to 2.0.08beta and it did not work anymore. Tried various times adding certificate. I ended in using the previous version v2.0.07beta and it worked directly.

Thanks for letting us know about this. I've just confirmed that I can reproduce the issue here. We'll investigate this and see about implementing a fix.

Having investigated some more, the client certificate does work in 2.0.8 - but you have to restart Burp for it to take effect. I'm not sure when this bug was introduced but I suspect it's somewhat older than 2.0.8. I'll continue investigating.

Thanks for your continued patience on this. I've just identified the root cause and applied a fix, which will be available in the next beta version of Burp.
