Firefox users:
Installation Get Adblock plus. (click on Installation at the top then on Install .... You can do this even as normal user, you don't need admin rights.
( If Firefox doesn't allow you to install the link, right-click the install link and choose "save link as". Save it (it's an .xpi file) on your desktop. Then open Tools/Add-ons in firefox and drag the XPI file into the new window that appears.)
Blocking a site
Go to tools/Adblock plus. Click "add filter" and enter the name of the site in the box.
Opera users:
There's nothing to install - site blocking is built in.
Blocking a site
1. Go to tools/preferences and open the advanced tab.
2. Click on "content" then on the "blocked content" button that appears.
3. Add the site you want to block.
How to block an ad
Find the source
If you see an ad you don't like, first find out where it came from. Adblock is easiest to use: Just click the adblock icon and a list of all images and scripts on the current page will pop up. You can even go through the list and it'll highlight the image currently selected. You can also just right-click the image and choose "adblock image ...".
Opera users can right-click an image and choose "copy image address", or right-click the page and choose block content.
Block the whole site
Don't block the specific ad though - rather block the whole ad site. Every time you visit a page, chances are the ad will be different - but from the same site. For instance, if you see an ad with an address like
www.adsite.com/images/ads/012345.gif
you'll want to block all of "adsite.com". In both cases (Adblock/firefox and Opera) there's a * symbol that means "everything". So cut off the address after the first / and put a * in: for instance
www.adsite.com/*
is what you'd add to the block list.
HTML popups
This is another way of a site generating popup windows. It is also the easiest to block: In firefox, Tools/Options, Content then tick "block popups". In Opera, press F12 and select the block option you want.
Java script ads and popups
Javascript is pretty much the only thing that can cause popups in firefox, and quite annoying ones too like a dialog box that appears telling you your computer is infected with spyware and would you please download our free program to remove it. If you do that, you're bound to have spyware on afterwards.
Blocking javascript
Adblock users once again just click on the icon, find any "script" entries and block the respective sites. Opera users can try View/source and search for "script" ... but it's a bit harder.
Turning off javascript entirely
This always works but you might lose some functions on some websites too. In firefox, choose Tools/Options, Content and take out the javascript checkbox. In Opera, just press F12 and there's your javascript checkbox.
Blocking with your Firewall
If you have a firewall on your home computer (and I hope you do!) then check the settings, most of them have an option to block certain sites too. Some antivirus/firewall products come with a popup blocker too.
EDIT : To block the ads on PureZC, try blocking all of "adbrite.com".

This isn't complete yet ... feel free to add or comment. Things I still need:
- A better way of finding scripts in Opera
- The whole thing for Internet Explorer
Any contributions are welcome. I'll edit this as I improve it.
