How can I automatically grab the contact data from a corporate homepage (or its imprint)?

How can I automatically grab the contact data from a corporate homepage (or its imprint)?

I'm frequently searching the web for companies and want to add them to my ZOHO CRM. How can I do that most efficiently?

Is there a plugin or workaround so that I do not have to copy and paste each field (Name, URL, Street, City, postal code, ...) individually but can automate this process as much as possible?

The only tool I found was evercontact zoho crm chrome plugin, unfortunaltey the plugin hat some errors and could not import to ZOHO CRM. Furthermore, I prefer firefox.
