Nice addon, but it has a minor bug when using it in Gmail.

The bottom of the page gets overlaped by the status bar, instead of pushed up.
Its specially noticeable when composing a new mail, because the bottom bar gets covered (the one with the send, format, attachment, discard, etc options).

It also affects the left-bottom buttons of gmail, the ones with the hangouts conversations and contacts.

For another issue, the toolbar button seems to do nothing. It doesn't show my current downloads, it just shows a big "downloads" button, a narrow "delete" button, and an empty list. Isn't it supposed to show the same downloads as the bar?

I hope you can fix those small bugs.

Otherwise nice addon!
