How can I upgrade my Mozilla Firefox 3.6.3 to the latest version for ubuntu?
I am using Mozilla Firefox 3.6.3 on my computer. But a message keeps coming while I use Firefox saying "You may want to upgrade your browser.
You're using an old version of Firefox that is no longer supported and may be insecure.
To upgrade, open Firefox's Help menu and click Check for Updates..."
But when I open Firefox's help menu, I can't see "check for updates" to click. What should I do?
