Rated 5 out of 5 stars

that is just perfect addon...i love it.
but when i upgraded to last version...it switches immediately to the new opened tab...how can i control that?????

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

You should double check the settings. Go to "Tools > Add-ons", and in the list select Speed Dial, then click on the "Options" button. In this dialog ("Speed Dial Options"), go to the "Controls" section, and you can configure anything there, like "Open in new tab", and "Open in background tab". If this is not what you were looking for, could you provide more details by contacting me directly?
