[qutebrowser] how to look at certificate cache?

[Greg Minshall]

hi.  apologies if this is a FAQ.

i occasionally see weird behavior that is *NOT* qutebrowser's fault.
but, to debug what is going on with some site, i think it would be
helpful to look at what qutebrowser (or whatever is running under it)
has in its cache of SSL certificates.  added niceness would be to be
able to clear an entry from the cache.

any ideas?

cheers, Greg
