You may just need to update the adblocker. Particularly if you 'updated' your browser. Sometimes then the adblocker gets knocked out of whack. I use firefox. I get daily/hourly requests to 'update' my browser for 'security and stability'. Nope, not me. Last time I did that I had all kinds of havoc to deal with. Getting the adblocker to function properly was only one of the many challenges last time.
