I've also started seeing this today, UA: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-GB; rv:126.96.36.199) Gecko/20071127 Firefox/188.8.131.52 This started happening just after greasemonkey updated itself, but I have since uninstalled that. I also recently updated colorzilla. I have tried reinstalling firefox, but with no effect.
I restarted computer after reinstalling FF, it works for me.
