Not even outdated anymore... Rated 1 out of 5 stars
I used to wait if this addon gets an update because I really liked it. But as it is abandonware for over two years now, I guess it's time to let it go.
And I find it a bit disturbing that there is still a button to donate. If the author doesn't care about this addon anymore and lets it rot, he should maybe have the decency to remove that.
I'm now giving this one a try: https://addons.mozilla.org/en-US/firefox/addon/addon-update-checker/
