I'm using 64-bit Ubuntu 12.04 LTS on my machine.
Currently, I'm using Mozilla Firefox 33.0(Mozilla Firefox for Ubuntu canonical - 1.0)
I'm not getting update option in menu Hrml->About Firefox but on when I visit few sites a pop-up appears at top of the browser window that asks me to update my current browser since it has become outdated.
But I don't know how to update my Firefox browser without Update link in Help->About Firefox menu.
Please provide me the best, effective and efficient solution on it.
Thanks in advance.
