Howdy, I sent the author of bloody vikings your way a while back. I'm here today because two extensions I regularly use are being detected by adwcleaner.
1. "ClassicThemeRestorer" https://addons.mozilla.org/en-US/firefox/addon/classicthemerestorer/versions/ (I am using the developer/beta edition.)
2. "SavedPasswordEditor" https://addons.mozilla.org/en-US/firefox/addon/saved-password-editor/
I'm hoping you can confirm these extensions to be false positives. (It's funny because auto-plugin-checker went/possibly still is undetected) since 08/05/2015, the developer auto-opted people into datamining without a changelog or announcement. Many people still don't know their privacy is being compromised by adware. See my review "langoliers" https://addons.mozilla.org/en-US/firefox/addon/auto-plugin-checker/
