You may workaround this script by spoofing your user agent.

It would say this instead:
You are not using Firefox

You are using Firefox but Adblock Plus is not active

Updated! Now works with Adblock Plus 0.7.5.2 (released 21. September 2007)
... yeah sure it's not :roll: I see a bunch of blocked Google AdWords that say different.

AdBlock Plus is installed *and* active, shows how reliable that code is.

the script doesn't pick up me, running linux/minefield. But still, it'd be nice to block certain javascript functions like this.

Well, this is not an ABP detector, but one for EasyList :-D

In fact, all those detection scripts I've seen so far rely on a specific filter list
entry to block a certain string - and thus can be circumvented by whitelisting
that single element.

Both...

Code: Select all

if(Components.interfaces.nsIAdblockPlus != undefined) hasABP = true;
checks to see if the interfaces is available, which is most recently fixed. The second pass is the function set_abp_status() which uses the honeypot style and actually detects filters, not ABP.

Yes some scripts on the net can still detect Ablock by trying to identify a specific filter.

I am talking about is, for this script particularly, when I switch the user agent, it simply shows up as:
"You are not using Firefox"

The script skip the parts which checks whether Firefox has installed AdBlock Plus or not, if it can't detect I'm using Firefox.

Haha... At least it works for this script.

It really is funny, all those ABP detection script authors seem to have
never heard about http://geckoisgecko.org/

In that case, this is a good thing 8)

Yes, nothing to see here - if somebody likes detecting EasyList, so be it. Just don't complain when Rick decides to change his filters.
