Do you mean Firefox 7.0 the version released in September of 2011? Unfortunately, it's not possible for forum volunteers to support such old versions of Firefox.

Or do you mean the current version of Firefox for Windows 7? Could you describe the problem in more detail: you double-click the Firefox shortcut and just nothing happens?

In that case, could you try starting Firefox in its Safe Mode. That's a standard diagnostic tool to deactivate extensions and some advanced features of Firefox. More info: Diagnose Firefox issues using Troubleshoot Mode.

If Firefox is not running: Hold down the Shift key (on Windows) or option key (on Mac) while clicking the Firefox icon.

A a small dialog should appear. Click "Start in Safe Mode" (not Refresh).

Any improvement?
