Convert adblock config files to privoxy format


adblock2privoxy [OPTION...] [URL...]


AdBlock Plus browser plugin has great block lists provided by big community, but it is client software and cannot work on a server as a proxy.

Privoxy proxy has good potential to block ads at server side, but it experiences acute shortage of updated block lists.

This software converts adblock lists to privoxy config files format.

Almost all adblock features are supported including

  • block/unblock requests (on privoxy)
    • all syntax features are supported except for regex templates matching host name
  • hide/unhide page elements (via CSS)
    • all syntax features are supported
  • all block request options except for outdated ones:
    • Supported: script, image, stylesheet, object, xmlhttprequest, object-subrequest, subdocument,document, elemhide, other, popup, third-party, domain=..., match-case, donottrack
    • Unsupported: collapse, background, xbl, ping and dtd

Tested with privoxy version 3.0.21. Element hiding feature requires a webserver to serve CSS files. See Nginx and Apache config examples provided.


Adblock files specified by [URL]... are converted to privoxy config files and auxiliarly elemHide CSS files. Local file names and http(s) addresses are accepted as URLs.

If no source URLs are specified, task file is used to determine sources: previously processed sources are processed again if any of them is expired. Nothing is done if all sources in the task file are up to date.


-v, --version
Show version number
-p PATH, --privoxyDir=PATH
Privoxy config output path
-w PATH, --webDir=PATH
Css files output path
Domain of CSS web server (required for Element Hide functionality)
-t PATH, --taskFile=PATH
Path to task file containing urls to process and options.
-f, --forced
Run even if no sources are expired

If taskFile is not specified explicilty, [privoxyDir]/ab2p.task is used.

If task file exists and privoxyDir, webDir or domainCSS is not specified, corresponding value is taken from task file.

If webDir is not specified and cannot be taken from task file, privoxyDir value is used for webDir.

If domainCSS is not specified and cannot be taken from task file, Element Hide functionality become disabled. No webserver is needed in this case.

domainCSS can contain just IP address if CSS web server has no associated domain. Use localhost or if you run your browser on the same machine with webserver.


Example of first run:

adblock2privoxy -p /etc/privoxy -w /var/www/privoxy -d -t my_ab2b.task my_custom.txt

Example of subsequent runs:

adblock2privoxy -t my_ab2b.task

The app generates following files

  • privoxyDir:
    • ab2p.system.action
    • ab2p.action
    • ab2p.system.filter
    • ab2p.filter
  • webDir:
    • ab2p.common.css
    • ab2p.css
    • [lot of directories for all levels of domain names]
  • taskFile:
    • special file containing execution details. It can be reused to update privoxy config from same sources with same options. Its name is ab2p.task by default.

How to apply results

  1. Install privoxy. Optionally setup it as transparent proxy. See privoxy installation manual for details.

  2. Change privoxy config file located in

    • /etc/privoxy/config for linux
    • C:\Program Files\Privoxy\config.txt for windows

    Add following lines:

    actionsfile ab2p.system.action
    actionsfile ab2p.action
    filterfile ab2p.system.filter
    filterfile ab2p.filter
  3. In order to make Element hiding work you also need a webserver to serve CSS files. You can choose nginx, apache or any other webserver. See nginx installation manual, apache on linux installation manual or apache on windows intallation manual for details.

  4. Change webserver config. In examples below

    • replace with your domain or IP address (equal to --domainCSS adblock2privoxy parameter)
    • replace /var/www/privoxy with your CSS files location (equal to --webDir adblock2privoxy parameter)
    • remember, these examples are simplified to use by unexperienced people. If you're familiar with webservers administration, you'll find better ways to apply these configs.

    Nginx config: add following lines into http section of nginx.conf file

    • for linus /etc/nginx/nginx.conf
    • for windows [nginx location]\conf\nginx.conf
    server {
          listen 80;
          #ab2p css domain name (optional, should be equal to --domainCSS parameter)
          #root = --webDir parameter value
          root /var/www/privoxy;
          location ~ ^/[^/.]+\..+/ab2p.css$ {
              # first reverse domain names order
        rewrite ^/([^/]*?)\.([^/.]+)(?:\.([^/.]+))?(?:\.([^/.]+))?(?:\.([^/.]+))?(?:\.([^/.]+))?(?:\.([^/.]+))?(?:\.([^/.]+))?(?:\.([^/.]+))?/ab2p.css$ /$9/$8/$7/$6/$5/$4/$3/$2/$1/ab2p.css last;
          location ~ (^.*/+)[^/]+/+ab2p.css {
              # then try to get CSS for current domain
              # if it is unavailable - get CSS for parent domain
              try_files $uri $1ab2p.css;

    Apache config: put following lines into

    • for linux: /etc/apache2/sites-available/000-default.conf (replace existing content)
    • for windows: C:\Program Files\Apache Group\Apache2\conf\httpd.conf (append to the end)
    <VirtualHost *:80>
          #ab2p css domain name (optional, should be equal to --domainCSS parameter)
          #root = --webDir parameter value
          DocumentRoot /var/www/privoxy
          RewriteEngine on
          # first reverse domain names order
          RewriteRule ^/([^/]*?)\.([^/.]+)(?:\.([^/.]+))?(?:\.([^/.]+))?(?:\.([^/.]+))?(?:\.([^/.]+))?(?:\.([^/.]+))?(?:\.([^/.]+))?(?:\.([^/.]+))?/ab2p.css$ /$9/$8/$7/$6/$5/$4/$3/$2/$1/ab2p.css [N]
          # then try to get CSS for current domain
          # if it is unavailable - get CSS for parent domain
          RewriteCond %{DOCUMENT_ROOT}/%{REQUEST_FILENAME} !-f
          RewriteRule (^.*/+)[^/]+/+ab2p.css$ $1ab2p.css [N]
  5. Get adblock2privoxy output

    • Either run adblock2privoxy providing privoxy dir, web dir, domain and adblock input file urls such as
    • Or just download processed lists from downloads page and unpack privoxy to and web directories content into
      • /var/www/privoxy and /var/www/privoxy for linux
      • C:\Program Files\Privoxy and [your webserver directory] for windows
  6. Restart privoxy and webserver to load updated configs
