I keep getting a pop-up that tells me to upgrade my operating system. How do I turn this pop-up off?

There's an annoying pop-up that loads every time I start Firefox. It tells me to upgrade my operating system, as the latest version of Firefox doesn't support it. But it's the most advanced version of the OS my system will cope with, so that's not an option.

For Windows 2000 also see:

On Windows 2000 this pop-up is generated by this extension:
Firefox Notification Hotfix 20120430.01:

So you can disable it to stop the popup.

jscher2000,

I just looked at VirtualBox. It appears that you need to set up another operating system with it. All I want to do is sandbox my browsers on Mac OS 10.4. Setting up another OS seems to me to be overkill.

Your Mac OS X 10.6 may already have build-in support for running applications in a sandbox.

You can do a Google search for mac sandbox

I am talking about Tiger, not Snow Leopard. I have more than one Mac. I would like to use the older one for browsing sometimes. I tried the method recommended on that page, but I got "command not found". I checked all the pathnames and they are correct. I put the firefox-sandbox file in the root of my home directory because that is where the Terminal starts. I tried another page on the same site to make Firefox itself into a sandboxed app, and that did not work either.

Update: I found another site that gave a method for sandboxing Safari, and tried that, but I still got "command not found" from the Terminal. I guess one cannot do that with Mac OS 10.4?
