When I use the arrow keys in firefox to go forward and back, the cursor erases tiny bits of the letters.

Even within this text field as I type, all is normal, but backspacing using the arrow keys (and then also forward spacing using the arrow keys as I return to typing) erases bits of the text. Once I begin typing again in this field, the erased components restore to normal. This effect can be captured in a screenshot. Upon closer inspection, there appears to be a second invisible cursor, one full character to the right of the visible cursor. So when arrow backspacing, the invisible cursor trails the visible one, wrecking the text behind. When forward spacing using the arrow keys the text gets wrecked in front of the visible cursor.

Try to disable hardware acceleration.

If disabling hardware acceleration works then check if there is an update available for your graphics display driver.

I use a Mac and my Tool option doesn't have Option. I'd sure would like to meet the ninny who decided we didn't need the forward and back arrows and give him a piece of my mind!!!!!

I am guilty of not following up. The above solution "appeared" to work for me until I realized that now, the text does not erase bits on the same line as my cursor but erases any text on the line below my cursor... so if I am typing above other text, these semi-invisible marks chop up the text below where I am backspacing. Yes, I know - put this in David Letterman's, "Museum of the hard to believe".
