For about a week or two, I have been reporting to ABP that ads were appearing on especially Lexulous (a game like Scrabble) and on The New York Times site. Yesterday the icon is no longer on my Firefox top-line menu. I have rebooted the computer. I have deactivated and reactivated ABP. I have re-downloaded and reinstalled the add-on. If I go to a site that needs to be whitelisted, it shows I have an adblocker on, but I cannot access ABP without the icon. ABP is activated on the Firefox Tools>Add-Ons list.
ABP version 3.1
It works in Safari and Chrome, but not Firefox. What else can I do to get Adblock Plus back working, please?
