My default browser is Chrome but I use IE occasionally as a back-up. I am trying to add Adblock Plus to the latter but this has a different name ("Easy ..") within the IE Gallery. If I try to add this as an extension the message comes up that I need to have the latest version of IE = 11 for this. I believe that I already have IE 11 but to be compliant I click on Download IE 11 (excluding Bing and MSN). It then says that it cannot complete the setup operation because IE11 is already installed. I have been round this loop several times and am getting giddy. Is there an escape?
