[stunnel-users] older browsers, stunnel and privoxy

[kovacs janos]

anyways, here is an article about what  i need:
https://en.wikipedia.org/wiki/TLS_termination_proxy

except it shouldnt pass the unencrypted data to a server but a browser.
on the same page, stunnel is listed under "Servers capable of acting
as a TLS/SSL termination proxy".
i would be grateful if i could finally make this work
