Sorry for the horrible English.
Trying to increase the size of the scrollbar in the browser.
Found information: http://www.vdomck.org/2007/07/change-scrollbar-sizes-in-firefox.html
But the browser profile is generated each time you boot the operating system.
How can I change this behavior?
Mike Kaply contributed an extension to widen the scrollbars, though you need to pass the API widescrollbars to enable it.
