How to Upgrade Firefox in Slackware 14.2 Current

In Ubuntu or Debian environment, updating a package will also update required packages (package dependencies). Unfortunately, this is not the case in Slackware.

Last night I was checking my Firefox's version and it seems that it's rather an old one. So I decided to upgrade Firefox with this command:

# slackpkg upgrade mozilla-firefox

The system will download the packages and then replace existing packages. But when I clicked the Firefox's menu in the Start Menu, nothing appears. Like most of Linux users, I tested it with running via terminal. When I typed:

$ firefox

It responds with these errors:

/usr/lib64/firefox/firefox: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.29' not found (required by /usr/lib64/firefox/firefox)

So it seems that Firefox is missing some of it's dependencies. The error message itself is not very clear, but I think it's gcc related issue. Let's update it:

# slackpkg upgrade gcc

When the installation finished and I run firefox command again, the Firefox window appears. Hooray, let's try open a web page. Uh oh, it's not working. All websites shows this error:

NS_ERROR_NET_INADEQUATE_SECURITY

Luckily, we have Google to ask. I managed to fix this error by upgrading mozilla-nss package.

# slackpkg upgrade mozilla-nss

Voila, now we have latest Firefox version running in our Slackware system.
