The theory is nice, too bad it doesn't work Rated 1 out of 5 stars

This does NOT install at all, but especially doesn't install a button on the toolbar, as stated it would. This occurs in both 3.5.3 and 3.5.4.

Perhaps when this actually installs and works right, it may be a good program. This never installed correctly. It states that it installed, I can set the options, but no toolbar button.

I'm sure I'll find something else that works when I install it just installing itself to a useless non-existent wasting storage space on my computer point.

This review is for a previous version of the add-on (1.021). 

Oh Mariah !!

I would advice you to read the description of an Add-on before you install it. Its clearly written in Eraser's description :

"P.S. :- Get this button by Customizing browser toolbar (Navigation/Bookmarks) by right clicking on it.
For setting up the preferences , just side click on the button. "

I agree just after installation it doesn't pop up immediately on the toolbar. My friend, you need to drag it there by customizing... i hope you got point :-)..
