How Can I Change the keyboard shortcut settings so ctrl+h opens my homepage; firefox ctrl+tab[new tab] opens blank page; or is there already a keyboard shortcut

You can't change those builtin keyboard shortcuts.

Alt+Home opens the homepage. Ctrl+T opens a new tab.

thanks! alt+home is what i was looking for

when i hit ctrl+t, i wish the page would be my home page, and not black, but alas

Sounds that your new tab page currently is a blank page You can set the new tab page via "Options/Preferences -> Home".
