I would like to change my cusor from vertical bar to block form, such as used on old green screens

Question

In IE the cursor can be changed to a block form, I can't find a way to do this with Firefox, the block form is an old carry back from the days of the old "green screens"

Answer 1

That pref still works in Firefox, just tried it in Firefox 10.0
Type '''about:config''' in the URL bar and hit Enter. <br />
''If you see the warning, you can confirm that you want to access that page.''
Right-click anywhere in the area of that window where the preferences appear. <br />
Then select '''New''' > then '''Integer''' <br />
Name: '''ui.caretWidth''' <br />
Value: '''7''' ''or any other whole number, decimals aren't allowed''
Then restart Firefox.
