Salut,

J'ai trouvé un petit script bien sympathique pour bloquer les pubs que je m'en vais vous faire profiter.
En gros il se charge de télécharger quelques différentes listes gratuites des mauvais hosts recensés, pour les placer dans un fichier placé dans votre @home qui sera, à votre charge, de déplacer où il se doit c'est-à-dire /etc/hosts à l'aide d'un simple:

sudo cp ~/.hosts-block /etc/hosts

Tout est décrit lors de l'exécution du script, c'est très simple, même moi j'y suis arrivé ^^
Vous pourrez ainsi désactiver ou virer complètement ADBlock selon l'envie et votre degré de satisfaction.
Firefox se sentira de suite plus léger et réactif.

#!/bin/bash

# If this is our first run, save a copy of the system's original hosts file and set to read-only for safety
if [ ! -f ~/.hosts-system ]
then
 echo "Saving copy of system's original hosts file..."
 cp /etc/hosts ~/.hosts-system
 chmod 444 ~/.hosts-system
fi

# Perform work in temporary files
temphosts1=$(mktemp)
temphosts2=$(mktemp)

# Obtain various hosts files and merge into one
echo "Downloading ad-blocking hosts files..."
wget -nv -O - http://winhelp2002.mvps.org/hosts.txt >> "$temphosts1"
wget -nv -O - http://hosts-file.net/ad_servers.asp >> "$temphosts1"

# Do some work on the file:
# 1. Remove MS-DOS carriage returns
# 2. Delete all lines that don't begin with 127.0.0.1
# 3. Delete any lines containing the word localhost because we'll obtain that from the original hosts file
# 4. Replace 127.0.0.1 with 0.0.0.0 because then we don't have to wait for the resolver to fail
# 5. Scrunch extraneous spaces separating address from name into a single tab
# 6. Delete any comments on lines
# 7. Clean up leftover trailing blanks
# Pass all this through sort with the unique flag to remove duplicates and save the result
echo "Parsing, cleaning, de-duplicating, sorting..."
sed -e 's/\r//' -e '/^127.0.0.1/!d' -e '/localhost/d' -e 's/127.0.0.1/0.0.0.0/' -e 's/ \+/\t/' -e 's/#.*$//' -e 's/[ \t]*$//' < "$temphosts1" | sort -u > "$temphosts2"

# Combine system hosts with adblocks
echo Merging with original system hosts...
echo -e "\n# Ad blocking hosts generated" "$date" | cat ~/.hosts-system - "$temphosts2" > ~/.hosts-block

# Clean up temp files and remind user to copy new file
echo "Cleaning up..."
rm "$temphosts1" "$temphosts2"
echo "Done."
echo
echo "Copy ad-blocking hosts file with this command:"
echo "sudo cp ~/.hosts-block /etc/hosts"
echo
echo "You can always restore your original hosts file with this command:"
echo "sudo cp ~/.hosts-system /etc/hosts"
echo "so don't delete that file! (It's saved read-only for your protection.)"
