Seems to have cropped up around the time of the latest update but I'm now unable to create or delete bookmarks. I've gone through the processes offered in the 'help' section (refreshed - made sure places.sqlite wasn't marked 'read only, deleted xulstore.json, double checked add-ons) and nothing's working. Short of hitting my computer with my shoe it would be MOST appreciated if one of your smart people throw me a bone on this one.
