Rated 3 out of 5 stars

This extension is a lifesaver for those who are doing research online as I was for senior paper. However it kept signing me out, and every time I needed to highlight something, it would redirect me to the Diigo homepage which was extremely frustrating because then I had to resign in for every new highlight. This completely counterbalances the convenience of persistent highlights. I find myself using this product less now as it takes me an extra 20 seconds each time I need to highlight something. It only did this recently though. I don't know what changed or why it does this now, but if the developers could work out that bug it would be great! I really need this program, but I don't want to fight with it all the time...

This review is for a previous version of the add-on (0.5.2007021000).
