Love it, though lately been aggravated about one issue.

What would cause the popup window to always open on my right-side monitor? I always open Firefox on my left-side monitor, but this addon now opens always on the right-side monitor, even if I drag or move it to the left side, the next time it opens, it will open in the center on the right-side monitor. It's so annoying, it's like it hardcoded to only open on my right-side monitor or whatever monitor is considered the "main monitor" more than likely, which still sucks!
