Firefox only shows a page that says XML Parsing Error: undefined entity Location: chrome: //browser/content/browser.xul. So I can't use any fix that uses ffox
After I first got the message I uninstalled Ffox and reinstalled it. Same message. So I can't get to any ffox menu, or buttons because I only have the one page with the message.
One suggestion was to uninstall and delete "firefox program file" but I can't find any file with that name on the C drive Mozilla Firefox folders
What can I do?
Additional System Details
I don't know. how can I tell.

Certain Firefox problems can be solved by performing 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:
- Windows: (Note: Check both folders.)
- C:\Program Files\Mozilla Firefox
- C:\Program Files (x86)\Mozilla Firefox
- Mac: Delete Firefox from the Applications folder.
- Linux: If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it - see Install Firefox on Linux. If you downloaded and installed the binary package from the Firefox download page, simply remove the folder firefox in your home directory.
- Windows: (Note: Check both folders.)
- 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!
I don't know how to find a desktop version of Firefox. There is just one download button
The 2 C: drive Mozilla Firefox folders each have 93 items but none of them is installer except a tiny text file. Is there another name?
You can usually find the Firefox installation folder in one of these locations:
- (64-bit Firefox) "C:\Program Files\Mozilla Firefox\"
- (32-bit Firefox) "C:\Program Files (x86)\Mozilla Firefox\"
As I said before, there is nothing labelled "Installation Folder" in those locations. Just a text document listing all the files that were installed.
Perhaps I should delete the entire Program Folder?
The folder you are looking for where Firefox is installed is named "Mozilla Firefox". "Installation Folder" is merely meant to point out that Firefox is installed in a specific folder and you shouldn't look for "Installation Folder", but look for "Mozilla Firefox".
Thanks for the responses. By saving an exe file, I installed a new version of Ffox with a bunch of directions about losing my profile unless I set up an account. I am still working on that but appreciate the responses.
