I've tried various ad blocking techniques over the short time I've had my N800 - GreaseMonkey (+Scripts), Adblock+, fakeweb with modified hosts file and currently the custom userContent.css file.

The userContent.css file blocks quite a lot of ads, although not as many as the large hosts file and fakeweb, and was was wondering about the performance hit from having a large hosts file compared to the relatively small userContent.css script.

Thanks for the nice write-up.

Thanks for telling me how. You chastise me for asking a question and then half-answer it.

Anyway. I'm going to try the CSS script and privoxy.
I did not chastise you. I didn't say anything personal at all, not did I mean to imply anything negative.
From the browser menu go to 'tools' -> 'components' : uncheck / check adblock plus

The idea is to use both. The big gain with the hosts over almost every other method (minus privoxy), is that it prevents the ads from even being loaded. This saves time, bandwidth, CPU and RAM.

But no, there is no hit with a large hosts. Instead of resolving the URL from a DNS server, it resolves from the hosts, which points nowhere.

So the userContent.css is post filtering the data being displayed after it's downloaded - similar to what some GreasMonkey scripts do? I was thinking it was also reducing the downloaded data... I need to do some tests.

Also, if I have a 50K host file doesn't the browser have to check every link address with the list before sending it out to the internet DNS? I was thinking about the time taken to perform this check.

The elements are still downloaded, they're just not displayed.

I'm fairly certain it just loads the info into whatever does the DNS looksup (as I believe a restart of the browser is required for changes to stick), so it's not an issue of polling the hosts file (which is a stupidly trivial thing to do anyway) and the impact is nil.

Either way, avoiding loading advertisements would most certainly make up for any slight performance hit of a large hosts file if there actually were one.

Make sure you do not mess up your original hosts file. See my post:

Exactly,
That's why in the few lines, I *append* the ad-blocking host to the current original one.

Linux newbie here. How do I append the ad-blocking host to the original one?

You need to install becomeroot or easyroot to allow root access (search www.gronmayer.com/it to find it) to modify the /etc/hosts file. You will also need to install wget if you want to follow the process outlined in post #10 above (copied here):

Code:
cd /etc
sudo gainroot
wget http://www.mvps.org/winhelp2002/hosts.txt
mv hosts hosts-orig
cat hosts-orig hosts.txt > hosts
rm hosts.txt
This assumes your downloading the hosts file from the web directly onto your N8x0. I downloaded the host file via the web browser (which removes the need to install wget) and saved it to the internal SD card, so my equivalent was (assuming the downloaded file was hosts.txt):

Code:
sudo gainroot
cd /etc
mv hosts hosts-orig
cat hosts-orig /media/mmc2/hosts.txt > hosts
The 'mv hosts hosts-orig' line backs up your original file and can be recovered using 'mv hosts-orig hosts' when your in the /etc directory with root access.

I hope this clarified things. I can't stress how much of an improvement running one of these host file additions makes to the quality of web browsing ( unless you like seeing all the ads ).
