I have been using my new laptop at work (my old one crashed at MAX) for two weeks and its been pretty good. Not because the laptop is something extraordinary, its because I installed the latest versions of all the softwares and plugins I use. And the most pleasant part of it is - it has been completely ads free. I did not notice it earlier but once I landed up on sys-con's site to read some article and I was pleasantly surprised to find no irritating video ad there. For a moment, I thought that may be sys-con has grown up but that was just for a moment :-). The snapshot shows it all.
Its actually a firefox plugin adblock plus that does it automatically. The most interesting thing was that it even removed google text ads. Its interesting because we have always seen Google promoting firefox and firefox as a browser closer to Google. So now a firefox plugin that blocks google adsense and in turn hurts Google revenue is certainly not going to go well with Google. It will be interesting to see how Google plays it.
So how exactly does adblock plus block the ads? Gecko engine - the engine underneath Firefox, uses a content policy which decides which content should be loaded and which should not. Adblock defines its own policy which gets added to the browser's policy. It comes with a predefined huge collection of filters and if the url to be loaded matches any of that, it does not let the browser make a request for it. For google adsense, the url contains 'pagead2' which you can see in the adblock preference below.
Its also going to hurt many bloggers as lot of them earn substantially from ads and mainly adsense. Even my blog page contains adsense but I dont mind adblock plus as I haven't yet earned anything from it anyway. I'm loving it. :-)
