Rated 4 out of 5 stars

I've been using yesscript for a long time but on XP 32-bit it doesn't work anymore. It works under Ubuntu but the statusbar icon is missing. v2.0 still works.

This review is for a previous version of the add-on (2.1.1-signed.1-signed). 

It now shows as regular toolbar button. If it doesn't come up by default, you can customize the toolbar to add it.
