Quote: esc does not turn off find in page box how do i disable it

I'm not sure I understand your question.

Does ESC work like it should and closes the Find bar and do you want to disable this feature (not possible AFAIK) or is the ESC key not working to turn off the find bar and you want to restore this feature ?

In case of the latter you can check for issues caused by extensions.

Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or userChrome.css is causing the problem.

• switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Themes
• do NOT click the "Refresh Firefox" button on the Safe Mode start window

Esc should close the Find bar if the cursor is in the box on that bar. If the focus has moved into the page, Esc won't be sent to the bar, it will be sent to the page instead. I usually press Ctrl+F to move the cursor back into the box and then Esc to close the bar if I don't feel like clicking the X button.
