Everything is deleted until I access Firefox. Windows Uninstaller will not delete it and not Revo Uninstaller.
Do you know how to remove Firefox from this machine?

I’ve had quite a bit of experience with myself, and I can often remove Firefox by installing a fresh copy on it and then using a free download called Geek Uninstaller to remove it. Follow the steps below to try it out:
1 – Visit this page and click the green Download Firefox button.
2 – Click the file you downloaded to install a fresh copy of Firefox on top of an existing Firefox installation.
3 – Download-Geek Uninstallerand unzip the zipped folder.
4 – Click the geek.exe file to launch Geek Uninstaller.
