If by "forward to the current site address dynamically" you meant "forward to the current address of one specific domain" then stunnel can achieve that by adding "delay = yes".

However, if I understood correctly, you wanted to let stunnel strip
or remove SSL for whatever sites you visit. Then no, I don't think you can achieve that with privoxy and stunnel. If that's what you want, I would suggest you use nginx to remove SSL. The following example configuration will let nginx "upgrade" your HTTP request to HTTPS.

events {} http { server {
    listen 80;
    location / {
            proxy_pass https://$host$request_uri;
            proxy_set_header Host $http_host;

You can then point any domain to the nginx server (for example, via the hosts file) and visit the site via HTTP. This will make HTTPS-oly servers happy.

That won't strip third-party HTTPS:// URL resources like NewIPNow does, but you can use the nginx "sub_filter" to replace HTTPS with HTTP in HTML. Also there are "security features" like "Content-Security-Policy" that prevent modern browsers from visiting your SSL-stripped sites, but I believe your out-dated browser will happily ignore those.
