The websites have been smart and can detect if user is running the adblock/adblockplus extension in order to avoid intrusive ads. I was saddened by this pseudo smartness of web developers but here is my hero: Ghostery – a new (to me) browser extension which works little differently than AdBlock et al. So far works like a charm, and hopefully will work as it expected in future.
AdBlock+, you will be missed. RIP.
