it's not Dafont related, it's your browser (apparently Chrome)

SearchBar is being filled automatically with old searches in HTML form if autocomplete="off" isn't available to tell the browser to not to autofill.

I hope you are using google chrome as your browser. and I will help to clear autofill data of your browser.
Instructions are listed below.

1. Click the Chrome menu icon in the browser.
2. Click on Settings option.
3. Now in the "Autofill" section, expand the area for which you wish to disable Autofill.
4. Toggle the setting OFF if it is on.
That's all!

thank you guys for the above and beyond help on this topic. hope it may help other as well...
