firefox 5 is not recognized by websites

Posted

Since upgrading to 5.0, many websites tell me my browser is not up to date (for example, if I try to sign up for Google +, it says my browser needs to be upgraded...same with some pages on FaceBook). This is keeping me from using some websites and quite annoying.

Not sure if it's related, but ever since I did upgrade, if I click on options on one of my add-ons, nothing happens except it renders the browser frozen and I can't click on anything without having to force close it and restart the browser.

Application

  • User Agent: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.1.5) Gecko/20091102 Firefox/3.5.5 FBSMTWB

More Information

Tried downloading and reinstalling 5.0.
I looked at my user agent and it says Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.1.5) Gecko/20091102 Firefox/3.5.5 FBSMTWB
That seems wrong to me...shouldn't it say Firefox/5.0? I installed the user agent switcher add-on, but get the browser freeze when I try clicking on options (happens to all add-on options, by the way).

In case you did not get why Ed gave you that link, you appear to be posting with a Firefox 3.5.5 useragent . It was not until Firefox 4.0 and newer that Mozilla made it so extensions could not tack stuff on end and potentially make the UA get stuck at the version one had when a the extension that affected it was installed.

Your useragent. Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.1.5) Gecko/20091102 Firefox/3.5.5 FBSMTWB
