Re: i upgraded firefox and still get the remark about this version not beeing supported
In your More system details... link on right it appears you are posting with the old Firefox 3.5.15
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:126.96.36.199) Gecko/20101026 BTRS31753 Firefox/3.5.15 ( .NET CLR 3.5.30729) Facicons
Some extensions that tack stuff on end of useragent may make all some part of useragent get stuck at a old version. The Facicons related extension installed at some point may be a culprit.
