That does sound like an improvement, but I haven't run across an easy way 
to enable that while disabling normal OCSP.

javascript is way too powerful to leave on for any old web site. Most 
web sites way over use it. Yes it is needed for web sites that are 
really applications, but most websites could be set up so they are 
usable without it. They just don't bother.

Having to install a third party package to do this doesn't make it simple. 
This feature should be built in.

Some people may not want to supply referer headers when moving around 
within sites. For that there should be a per domain override similar 
to cookies.

Web sites should work just fine without a supplied user agent. If they 
don't, they are broken. bots can forge common user agent strings easily, 
relying on checking for user agent for security purposes is silly. 
A number of sites think there are only 3 or 4 different browers and refuse 
to work if you aren't using one of them. Other web sites aren't designed 
to handle the optional user agent header not being supplied and will 
break needlessly.
