This addon has caused nothing but problems for me across many websites. Adobe's website doesn't show prices, a photo downloader wouldn't retrieve the file, a Microsoft Sharepoint site wouldn't load any of the files, and other problems with Samsung, some forums and even Google. All solved by disabling the addon. I'm doing SO MUCH disabling that it's not even worth having it. I've never had these problems with AdBlock Plus. UGH!!!
EDIT: Also just found out it was this plugin responsible for making Paypal give me errors where it was impossible to pay. Worked as soon as I disabled this. This is with no custom filters. Madness. Definitely removing now.
