Recently I've noticed that Adblock Plus doesn't block Google ads anymore. The page is just full of ads. Here's a query for "SSL" with Adblock Plus turned on.
I would like to not see Google ads in my browser. How do I get the previous behavior back?
As @djfdat already said: You have to disable "Acceptable Ads".
This has nothing to do with your Google query for SSL or SSH. It's just that all Google websites are in the "Acceptable Ads" whitelist.
Google (and other big companies) were asked to pay money by a firm called EYEO GmbH to show their ads. This firm owns Adblock Plus together with its main developer Wladimir Palant. And big player firms like Google accepted their offering.
Key statement on techcrunch
The Adblock Plus company blackmail websites in that way: "If you don't pay us, we block all your advertisements. We have 50 mio. users and the power to ruin you." The techchrunch article doesn't go into details, but the blog articles linked above do. They fake user reviews, even whole websites, conspire with big ad firms to white-list them and block those who doesn't pay. Thats criminal and I recommend you not to use this plugin aynmore in any browser.
In your Adblock Plus Options > Filter Lists, make sure you're subscribed to Easylist. Also, turn off the last checkbox on that tab for 'Allow some non-intrusive advertising'.
I just modified the "Acceptable Ads" list.
Actually, I deactivated Adblock Plus's list in the preferences, then I downloaded the source text file (you can find the link in the prefs dialogue) and removed all lines that I didn't like (Google and Amazon).
Then I added the new filter list and, lo and behold, Google ads disappeared again.
Since I wrote a script for that task, I can do that again at any time. It's some work, but for me it's the best solution, because I still have all "non-intrusive" ads white-listed except that from Google and Amazon.
I added the filters via a filter file I put on my own local server, so I could subscribe to my own list. But, I think, you can also add the filters manually.
