I'm getting the XML Parsing Error message on Firefox after the latest update. I have tried every fix I can find in the help guide and the community section but none of them have worked. So far I have: 

- completely uninstalled Firefox and everything related
- emptied cache of Chrome (which is what I am using to re-download Firefox)
- deleted everything in Windows Temp folder
- re-downloaded a brand new download of Firefox directly from the site
- run a full clean re-install of Firefox (same error message)
- restarted the computer (still getting XML Parsing error)
- unable to start Firefox in safe-mode as I don't have the button on the browser to do so.

Any other suggestions would be greatly appreciated as Firefox is my favourite browser and I want it back!

Thanks for your solution Cor-el.

Unfortunately that hadn't worked either, but last night in one last-ditch attempt before giving up until the next update, I deleted the installer, re downloaded it and ran it without uninstalling my current version of Firefox. It prompted me to run the 'Reset Firefox' solution so I tried that (which I thought I had tried previously, but perhaps not after having cleared caches and things) and that worked.

So Firefox is up and running again.

Can you attach a screenshot?

You can create a new profile as a quick test to see if your current profile is causing the problem.

See "Creating a profile":

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.
