Firefox 4.0 Downgrade

Having trouble getting used to Firefox 5.0 without support for some of your most used addons because the providers of those plugins don't yet support the newest version of Firefox? We've had trouble with several plugins and toolbars like the Google Toolbar, AVG Anti-virus, avast Antivirus and many others.

We found the firefox web site difficult to navigate to find the version 4.0 file so we've created this page especially for users wishing to downgrade to maintain functionality of Firefox plugins.

There's really very little difference between Firefox 4.0 and Firefox 5.0 except for the support of extensions and plugins. This is a free download link *directly* from a mirror still hosting version 4.0 from Mozilla.
