Rated 5 out of 5 stars

No confirmation display on Firefox 25+ but the add-on still works.

I am getting a 404 on the author's support site so here is a simple fix. Open up overlay.js and replace the following:

document.getElementById("statusbar-display");

with:

gBrowser.getStatusPanel();

I found the fix here on the following Mozilla page:

This review is for a previous version of the add-on (0.62). 

Thanks! This is fixed now.
