I am running Ubuntu 14.04 LTS 64-bit and the version of Firefox that comes with this version of Ubuntu. I recently went to a website and got a notification that my version of Firefox was no longer supported. I was not aware that Firefox was not being updated as I update regularly. I tried updating from the command line as well as using the Ubuntu Software Updater but neither of these work and my Firefox version is still stuck. I have researched online and have tried adding the Firefox security PPA as well and installed that but when I launch Firefox it is still the same old version that opens.

  • What version of Firefox do you actually use? – s3lph May 16 '15 at 22:56
  • What message is returned when you try to update it from command line? And/or what do you see when you try it from the software center? – juanjalvarez May 16 '15 at 22:57
  • Firefox in 14.04 is at ver. 38, quite doubtful that any website would call it " not supported". Maybe take a closer look at what your issue is or post a link to this website. – doug May 16 '15 at 23:50
  • Maybe it's got to do with "Flash"? Some sites want the latest-n-greatest version available by default with Google Chrome. – DK Bose May 17 '15 at 1:59
  • I think it's just an ad. What's the site? – TheWanderer May 17 '15 at 2:07

I eventually tracked down the issue to a plugin I had installed a while back that allows you to modify the header information to look like your using a different OS and browser so the sites I visited were thinking I was on Windows and using an older version of Firefox.


Firefox 38 is the latest version. I'm pretty sure, if it's a ribbon at the top, or a box in the site, that is an ad. Ignore it.
