I just found privacy protector, you can ditch eraser, this one is similar. https://addons.mozilla.org/en-US/firefox/addon/privacy-protector/

The Click&Clean addon seems to do the same as Eraser and it's updated to 4.0. I liked Eraser but since it's not being updated, have to go with a next best thing.
