Just put Mozilla Firebird on the clients:
Then check out the Ad-blocking local CSS tricks at floppymoose. No
proxies, no plugins, just a simple static modification to your local
cascading style sheet:
I run both the browser and the css changes on both Linux and Windows
and pop-up blocking is impeccable. Ad-blocking is probably in the range
of 50-60%. Pretty good for a short list of stuff and no extra proxy
services to set up.
Recently, I had the bad luck of going several rounds with Symantec's
Ad/Pop-up blocking technology which as far as I could tell was some sort
of transparent proxy which made several websites I went to stop working
altogether. Block ads and pop-ups? It sure did, but I found it came
down really hard on sites which didn't have pop-ups but relied on
no response either from the website or from Symantec's NIS product. I
finally just turned it off altogether and let Mozilla Firebird do it's
thing on its own. It really made me appreciate how intuitive and
accurate the Mozilla Firebird pop-up blocking actually was.
