I have access (and the general public) to a computer lab with many workstations. Each workstation is identical in terms of software, hardware and the version of firefox.
The version that is installed is 21.0, and the latest (as of this writing) is 33.3. After noticing the version I do not use Firefox on these computers, instead using TeamViewer to connect to my computer and use the browser there.
Does it matter that much if an outdated version of firefox is being used? I'm concerned because I would imagine that many security fixes would be in place since then.
