It would be helpful, if you could post the build ids of adblock plus, element hiding helper and Minefield. It helps to track down issues.
For example, here is mines
Adblock Plus 1.3a.20100828
Element Hiding Helper for Adblock Plus 1.1a.20100819
Minefield 4.0 b5 pre
Btw, the versions of adblock plus and element hiding helper are the latest ones available when i am writing this post. If you are not running the latest version try updating them. I would also recommend you to update your Minefield version if you are not running the latest Dev build.
You can grab adblock plus and element hiding helper dev builds from here - https://adblockplus.org/en/development-builds
