I've tried all of the search results suggestions I could find here, but none of them help. The Password
box remains grayed out. This is the latest version of FF. I use the latest Keyscrambler, addblock, Noscript,
Wot, greasemonkey ,Flash video downloader, and better privacy(disabled). Windows firewall and MS
security essentials and the operating system is Win 7 Home 64 bit. Would really like to get this solved.
Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Firefox uses the about: protocol to access built-in about: pages that you can open via the location bar just like you open web pages.
