Might have found a bug. I'm starting Chrome in incognito mode automatically with the "--incognito" flag. I use the "allow in incognito mode" option for the extension. I select "hide button" from the Adblock Plus button, but nothing happens. The button stays visible. By the way, the "Show Button" option does appear in "chrome://extensions/".
Can you fix this? As much as I appreciate Adblock Plus, I'd rather hide the button.
