What steps will reproduce the problem? Simply install Pencil-1.3-4-fx.xpi to your Firefox 9.0.1. If the new Firefox GUI (default) is active, there is no way to start Pencil. Please have a look at the attached screenshot.

What is the expected output? What do you see instead? If I switch to the old Firefox GUI (activating the old menu bar), it is accessible from the Extras menu.

What version of the product are you using? On what operating system? Pencil 1.3.4 with Firefox 9.0.1 and Win7 x64.

look for the pencil icon in the lower right hand corner of firefox

Oh thanks, I didn't see this tiny icon. Well I guess that I'm not the only one who overlooked this icon.

This means Pencil still overlays the old statusbar element, and has not been updated to the Firefox 4 Addons Bar, which houses user-movable toolbar buttons. Is changing that on the radar?

I also searched for a LONG TIME before installing the bundled version...

Consider adding a bigger icon, or something.
