XML Parsing Error
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.

Does this help? https://www.bing.com/search?q=XML+Parsing+Error
Unfortunately it doesn't seem to have.
Can you attach a screenshot?

- use a compressed image type like PNG or JPG to save the 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.

That was very good work. Well Done.
