Just sadly noticed ABP doesn't seem to work while I'm in incognito mode.
e.g. have ABP (1.0.26) installed, with Chrome's latest version (9.0.597.98) and set the subscription list to EasyList FR.
Then load http://www.lemonde.fr/ in both normal mode & incognito mode.
In normal mode, no ads.
In incognito mode, ads are loaded.
PS: the "Save" button below the text area while posting a new topic doesn't work, it asks me something about attachments, then says I'm a spammer. :p
