Sometimes many links are 'forgotten' (not found) Rated 3 out of 5 stars
Well, the idea of SLP is quite good - no question. But there are enough situations and sites, where SLP oversees a lot of links. Perhaps it would help, if there would be a possibility to send the developer Links of sites where SLP fails and as well the links, which aren't recognized.
This happened on FF 22.0 Beta latest and Windows 7 64.
