Over the weekend, Toolbar Buttons passed the 2,000,000 download mark on addons.mozilla.org! At one point I though that might happen never the end of this year, but being the featured add-on this month has made downloads go so fast, it has been a great experience to watch.
I am hoping to get the next release out soon, with a whole lot of improvements, just some bugs I am having problems with. I also hope to start releasing some versions of that Toolbar Buttons that are collections of buttons based on particular themes, such as Tabs, or Bookmarks or Developer Tools. I have also been in contact with the maintainers of LXLE Desktop who are interested in making a version of Toolbar Buttons installed by default in their distribution of Linux. So much going on, it is amazing!
