Problem with Sorting Rated 5 out of 5 stars
Great addon. Makes proxy config. a lot easier. One problem; when a csv file(like the one on previous review) is imported, sorting up&down doesn't work. But, when the proxy is entered manually, it works.
I had same problem too. You should check other installed extensions. I tested disabling all other addons one by one to discover which one causes that and the conflict was of "Alexa Sparky" addon. Then I removed it, and installed other similar tool called "SEO Analysis". No more conflicts.
