Its a handy tool for saving page clicks but I have found that it eats up a lot of cpu resources when several tabs are open. I have decided to keep it disabled unless I am going to do some significant searching.
This review is for a previous version of the add-on (0.4.0.4).I just create a performance tuning tip, may help for your case http://www.teesoft.info/content/view/74/35/lang,en/
