Not currently working with Craigslist, my main need. I get "There was an error loading this page" in each hover-box there.

Where it does work, e.g. at Rhymezone, need is to have a bigger hover-box. But making it bigger only lasts for that hover. Opening another hover-box from the very same page reverts to using the tiny box! How to make the bigger box setting stick for a site?
