Honestly, I didn't even stored the ad plugin for my FF... But, the recently adsense earning is gradually decreased and it's due to the economic crisis, not the ad plugin.
those that uses plugins are more internet savvy and has less tendency to click on ads as the common users.
If you are really concerned with people getting "free" content, you could always dig into the plug-in, figure out how it's removing the ads (i.e. CSS display:none), and code your site to be hidden (or display a "requires IE" message) when AdSense is hidden. Not sure if there is a way to see your users add-ons. If so you could do it that way as well. Personally, I'd rather keep the content free for the other benefits you get even when no ad is being displayed.
I think you might need more web development experience in order to do what I laid out. If you had enough web development experience to accomplish this, you would have understood what I was explaining. I'm not trying to be short or harsh. It just doesn't do any good to go into more detail if you don't have the tools to accomplish it. You'd probably have to have 5,000hrs web dev experience under your belt ...which a surprisingly large amount of people do.
Put firefox in to fire . If they made a plugin like this for revenge, I will stop using firefox and I request all adsense users to reject it. Obviously firefox will lost a huge number of users and it will go to fire itself .
Emm.. This plugin was created before chrome. Maybe that was why Google build Chrome? Anyway, only webmasters will use this plugin and with the plugin webmasters will not see the ads and will accidently click on the ads. Better clicks for those with webmaster traffic
Unless it's installed by default the impact is going to be negligible. My stats suggest there is nothing to worry about. Dean
that's how things are... if you want to block ads, you block them... you can't tell people "dont use adblockplus!" because what you're really saying is "click the ads"....
