hi, I'm using firefox for android on a handheld scanner with some warehouse software running via webpages through firefox. I'm searching for stock details by scanning the barcode into a field on a form, which sends me to a stock page..which is great, but when i hit the back button to return to the stock lookup page, it's remembering the barcode in the form. is their a way of clearing the fields in a form upon going back with browser back button. Not sure if i can control this via a setting in the about:config page.
