How did you remove the registry? Did you uninstall FF before doing this? If messed up the registry removal there is nothing anyone can do to help if you mess that up.

Hi Yes I remove Firefox first.

Thanks

...there are so old entries Mozilla 4.0 listed in the registry and these cannot be deleted.

Can you right-click > Copy Key Name on the key(s) you found and paste them into a reply?

Note that "Mozilla 4.0" may be part of the user agent string of many other browsers that needed to use that back in the day for compatibility reasons. It doesn't necessarily have anything to do with Firefox.

Can you attach a screenshot?

Hello,

Please find the key below that is in the registry that I cannot remove Mozilla/4.0 (compatible; MSIE 6.0; Windows NT; MS Search 4.0 Robot).

Hope this help.

Thanks

Matthew

MSIE 6.0 is Internet Explorer 6, but "MS Search 4.0 Robot" isn't familiar. I don't know what that corresponds to.

That is a user agent string.

Under what path do you see these items in the Windows Registry?

Hello,

Thanks for coming back to me, I will leave it as it is.

Thank you for your help.
