I was baffled that Firefox did not come with the option to print upon "right-clicking" on a page. After a quick search, I found and installed this plugin. Wow, it's surprising how such a small feature can be such a game changer! Thank you for saving my sanity!! Love this thing! And yes, I will donate!!
Having a print menu item is fantastic, but this add-on has not been updated since Firefox v4. I have an updated version of this add-on called "RC Print" that is compatible with the current version of FF.
