Yesterday I updated the Firefox to 16.0.1. Today I placed the Firefox icon on my dock so each time my computer comes on the icon is displayed. Somehow, yesterday the icon vanished from the dock when I shut my computer off. Can you please help? Doesn't Firefox have a firewall? I am rather new in operating computers in general. I have an iMac desktop.

Try to reinstall Firefox (download a new dmg file) and trash the current version and install a newly dwonloaded version if the Firefox application doesn't stay on the Doc.

You can find the latest Firefox release in all languages and for all Operating Systems here:


Make sure that Firefox gets installed properly.

Open the Firefox disk image (DMG) file and drag the Firefox program to the application folder on your hard drive. You shouldn't double-click the Firefox application to run it from the disk image, but drag it out of the DMG folder instead.
