osx - Complete Adblock in Google Chrome

I use a Mac and I want to completely block ads on my Google Chrome browser. What I mean by completely is that I don't want the ads to be just hidden. I understand that Google Chrome adblock addons currently hide ads, but can't prevent them from downloading. Is there a work around to this problem?

Also, I use Firefox as my primary browser and I am on a proxy server on a Local network.

I am having trouble running the shell script. This is the code that I have

#!/bin/bash
#
EASYLIST_URL="http://easylist.adblockplus.org/adblock_rick752.txt"

TEMP_FILE="/Volumes/Sites/MacDownloads/bfilter/bfilterList.tmp"
LOCAL_LIST_FILE="/Volumes/Sites/MacDownloads/bfilter/urls.local.save"
OUTPUT_FILE="/Volumes/Sites/MacDownloads/bfilter/urls.local"

WGET="/usr/local/bin/wget"
CAT="/bin/cat"
CONVERTER="/Volumes/Sites/MacDownloads/bfilter/adblock2bfilter.pl"
BFILTER="/Volumes/Sites/MacDownloads/bfilter"

${WGET} -q -O - ${EASYLIST_URL} | ${CONVERTER} >${TEMP_FILE}
if [ -s ${TEMP_FILE} ]; then
    echo "Updating BFilter URLs:"
    if [ -f ${LOCAL_LIST_FILE} ]; then
        ${CAT} ${TEMP_FILE} ${LOCAL_LIST_FILE} >${OUTPUT_FILE}
    rm ${TEMP_FILE}
    else
        mv ${TEMP_FILE} ${OUTPUT_FILE}
    fi

    chmod 640 ${OUTPUT_FILE}
    ${BFILTER} restart
    echo ""
fi

I get the error Macbook:bfilter CALVIN$ ./bfilterUpdateLists.sh ./bfilterUpdateLists.sh: line 14: /Volumes/Sites/Mac: No such file or directory

You could probably set a hosts.txt file, pointing known ad domains - something like this would work, assuming OS X uses a standard host.txt format (which it seems to). Unlike other options this will work systemwide, and not need any additional software.

If you are thinking about the most popular version of AdBlock chromeadblock.com which is used by circa 2 million people, take a look at the changelog:
"New in version 2.0: Ads are blocked from downloading, instead of just being removed after the fact!"

You can use a proxy. That's the ONLY way at the minute to do the block. Personally I use BFilter since that's the fastest, BEST so far (tried Privoxy, AdMuncher (this really s..ks)). BFilter provides MAC binaries, hope they work for you. Download page. Here you can read a howto about using ABP filters. I have one, http://shiki.hu/stuff/merged.txt (some hungarian adservers, easyprivacy, easylist DE, easylist). You have to set this URL into the scripts ... or do the merge by hand (like I did). (IF you want, I can put up my list from my BFilter folder!)

After you've done with the setting up, you have to modify the chrome shortcut. You have to add the
--proxy-server=127.0.0.1:8080 (I use the :9999 port, you can set it in the bfilter config). So the whole shortcut will be like: ...Application\chrome.exe --proxy-server=127.0.0.1:8080 (Yeah I use a PC/Windows, don't burn me for that, but you can see the example from that I guess).

Forgot. You can use it as a transparent proxy, just use the settings menu (if you have one on MAC) or set it up in the config file. If you are stuck comment/ask.
