Not working now Rated 1 out of 5 stars

Since upgrading Firefox to 3.6.18 this no longer works. The icon is there, but when I click it nothing happens. Completely dead. It used to be good when it worked. I can still use the website and Evernote overall is good. The Shareaholic add on works with Evernote perfectly and I will use that instead now.
I wonder if it is defaulting to a desktop Evernote client which I don't have (as there is none for Linux) even though it is set to use the web instead.
So, Evernote Corp, when can we have an Evernote client for Linux desktop? I already have it on my Android Linux phone, so why not my Ubuntu Linux desktop?

This review is for a previous version of the add-on (4.0.0.155231).
