Any browser that can be configured to use a proxy, which - should be virtually all browsers, including - Firefox, Internet - Explorer, Opera, and - Safari among others. - Direct browser support is not an absolute requirement since - Privoxy runs as a separate application and talks - to the browser in the standardized HTTP protocol, just like a web server - does.
At present, Privoxy is known to run on - Windows(95, 98, ME, 2000, XP, Vista), GNU/Linux (RedHat, SuSE, Debian, - Fedora, Gentoo, Slackware and others), Mac OSX, OS/2, AmigaOS, FreeBSD, - NetBSD, OpenBSD, Solaris, and various other flavors of Unix.
But any operating system that runs TCP/IP, can conceivably take advantage of - Privoxy in a networked situation where - Privoxy would run as a server on a LAN gateway. - Then only the "gateway" needs to be running one of the above - operating systems.
Source code is freely available, so porting to other operating systems - is always a possibility.
As long as there is some way to set a HTTP proxy for the client, then yes, - any application can be used, whether it is strictly speaking a - "browser" or not. Though this may not be the best approach for - dealing with some of the common abuses of HTML in email. See How can I configure Privoxy - with Outlook Express? below for more on - this.
Be aware that HTML email presents a number of unique security and privacy - related issues, that can require advanced skills to overcome. The developers - recommend using email clients that can be configured to convert HTML to plain - text for these reasons.
All browsers must be told to use Privoxy - as a proxy by specifying the correct proxy address and port number - in the appropriate configuration area for the browser. See - the User Manual for more - details. You should also flush your browser's memory and disk cache to get rid of any - cached junk items, and remove any stored - cookies.
If you set up the Privoxy to run on - the computer you browse from (rather than your ISP's server or some - networked computer on a LAN), the proxy will be on 127.0.0.1 - (sometimes referred to as "localhost", - which is the special name used by every computer on the Internet to refer - to itself) and the port will be 8118 (unless you have Privoxy - to run on a different port with the listen-address config option). -
When configuring your browser's proxy settings you typically enter - the word "localhost" or the IP address "127.0.0.1" - in the boxes next to "HTTP" and "Secure" (HTTPS) and - then the number "8118" for "port". - This tells your browser to send all web requests to Privoxy - instead of directly to the Internet. -
Privoxy can also be used to proxy for - a Local Area Network. In this case, your would enter either the IP - address of the LAN host where Privoxy - is running, or the equivalent hostname, e.g. 192.168.1.1. - Port assignment would be same as above. Note that - Privoxy doesn't listen on any LAN interfaces by - default. -
Privoxy does not currently handle - any other protocols such as FTP, SMTP, IM, IRC, ICQ, etc. Be sure that - proxying any of these other protocols is not activated. -
Did you configure your browser to use Privoxy - as a proxy? It does not sound like it. See above. You might also try flushing - the browser's caches to force a full re-reading of pages. You can verify - that Privoxy is running, and your browser - is correctly configured by entering the special URL: - http://p.p/. - - This should take you to a page titled "This is Privoxy.." with - access to Privoxy's internal configuration. - If you see this, then you are good to go. If you receive a page saying - "Privoxy is not running", then the browser is not set up to use - your Privoxy installation. - If you receive anything else (probably nothing at all), it could either - be that the browser is not set up correctly, or that - Privoxy is not running at all. Check the log file. For instructions - on starting Privoxy and browser configuration, - see the chapter - on starting Privoxy in the - User Manual.
First, make sure that Privoxy is really running and - being used by visiting http://p.p/. You - should see the Privoxy main page. If not, see - the chapter - on starting Privoxy in the - User Manual.
Now if http://p.p/ works for you, but - other parts of Privoxy's web interface show - the dummy page, your browser has cached a redirection it encountered before - Privoxy was being used. You need to clear your - browser's cache. Note that shift-reloading the dummy page won't help, since - that'll only refresh the dummy page, not the redirection that lead you there.
The procedure for clearing the cache varies from browser to browser. For - example, Mozilla/Netscape users would click - Edit --> Preferences --> - Advanced --> Cache and - then click both "Clear Memory Cache" - and "Clear Disk Cache". - And, Firefox users would click - Tools --> Options --> - Privacy --> Cache and - then click "Clear Cache Now".
