Firefox will not operate at all on my Windows 7 PC. Any help?
FireFox used to work on my Windows 7 pc, however it will no longer even execute startup. I get a window popping up asking "Would like to allow Mozilla to change settings on this hard drive?". I select yes, and then nothing happens. I have uninstalled and reinstalled the software about a dozen times and nothing changes. I really need help with this as my business runs exclusively on Mozilla Firefox.

Hello,
Maybe you could try to do a Clean reinstall. This means you remove your Firefox program files and then reinstall Firefox. This process does not remove your Firefox profile data (such as bookmarks and passwords), since that information is stored in a different location.
To do a clean reinstall of Firefox, please follow these steps: Note: You might want to print these steps or view them in another browser.
- Download the latest Desktop version of Firefox from mozilla.org (or choose the download for your operating system and language from this page) and save the setup file to your computer.
- After the download finishes, close all Firefox windows (or open the Firefox menu
and click the close button 
).
- Delete the Firefox installation folder, which is located in one of these locations, by default:
- C:\Program Files\Mozilla Firefox
- C:\Program Files (x86)\Mozilla Firefox
- Now, go ahead and reinstall Firefox:
- Double-click the downloaded installation file and go through the steps of the installation wizard.
- Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.
More information about reinstalling Firefox can be found here.
WARNING: Do not use a third party uninstaller as part of this process. Doing so could permanently delete your Firefox profile data, including but not limited to, extensions, cache, cookies, bookmarks, personal settings and saved passwords. These cannot be easily recovered unless they have been backed up to an external device! See Back up and restore information in Firefox profiles.
Please report back to say if this helped you!
Thank you.

Note that this can happen if Firefox is set to run as Administrator.
When this happens again then check that Firefox isn't set to run as Administrator. Right-click the Firefox desktop shortcut and choose "Properties". Make sure that all items are deselected in the "Compatibility" tab of the Properties window.
- Privilege Level: "Run this program as Administrator" should not be selected
- "Run this program in compatibility mode for:" should not be selected
