How can I fix a broken Firefox extension in Windows?

I downloaded Malewarebytes a while back after my computer wouldn’t let me access anything without reading it as a virus. After I cleaned it, I had over 200 viruses most (like 92%) HKey_root files.

After that an extension in Firefox (Download YouTube videos+ 8.0) stopped working. When I download from sites it will get around half way and stop the download by itself and never complete. I am thinking the files were damaged and was wondering how to fix them. I don’t have a system reboot disk.

    possible malwarebytes blocked ips (sometimes MBAM denies communications)?, changed hostfiles?.... uninstall firefox, reboot clean windows then reinstall firefox and all plug-ins and try it again.

    I also faced this side effect of malware bytes, it removes what is useful to you.
    I took my revenge and removed malware bytes from my pc.
    I think it give you the option setting everything as it was, when you uninstall it.

    Are you not able to install that particular addon or can't install any other addon ?
    Try this : https://addons.mozilla.org/en-US/firefox/addon/video-downloadhelper
    It will do what you are looking for.

    Hello, you could try disabling and then removing extension and then restart browser.  Download and install extension again.  That should fix it.  Make sure your system is totally clean by using following software to give full scans:

    -- malwarebytes you already have
    -- Superantispyware:

    -- a full scan with your antivirus.  If you do not have any installed, make sure to install one.  There are several options in the next link:
