Rated 2 out of 5 stars

In theory, this is a nice extension. In practice, it periodically changes the focus. For example, if I have one FF3 window open, and I select Tools/Add-ons, after a few seconds, it switches focus back to the main FF window. When I disable the extension, this behavior goes away, and when I re-enable the extension, the focus-switching returns.

I'm guessing this happens when the extension goes to copy the current FF window content, so that it can show the preview in the speed-dial window. I'm also guessing that it doesn't do this for everyone, so it may be that it doesn't play well with one of my other extensions.

This review is for a previous version of the add-on (0.7.1). 

This happens because a website assigned to Speed Dial is requesting focus through Javascript when it's refreshed.

To solve that, disable the JavaScript in the background browser (Speed Dial options panel, "Advanced" section. "Other" tab).
