Just upgraded to Firefox 50.1.0 but problem that has existed thru last several upgrades, maybe for a year+, continues. Many sites, Flickr, Youtube, Mozilla (!), et al, think I am using a deprecated version, apparently v.21. I have been unable to figure out how to correct this.

Youtube, e.g., returns the message "...the user agent string reported by your browser...We received: Mozilla/ 5.0 (masking agent; rv: 21.0) Gecko/20100101 Firefox/21.0,gzip(gfe)

Despite annoying messages, everything seems to work correctly, I would like to correct this.

Thank you. Resetting "general user agent override" solved the problem.
