Well I had a somehow bad experience. Tried saving my firefox passwords,
but Firefox doesnt' have any stored passwords exporting form
(edit/configuration/security/stored passwords, if anyone knows how to
export them, please.), so I did an OCR to my firefox screenshots. 

The best I did was with gocr, due to its configuration options, making
tests of best configurartion options

1. used Dejavu fonts on my screen
2. resized the image (bigger), letter height about 20 pixels
(uppercases) 
3. tried a lot of attempts playing with certainty and space sizes:

for a in $(seq 95 100); do 
for s in $(seq 12 25); do 
gocr -s $s -a $a screen.jpg
echo s, a
read
# this read command allows you to explore your text on screen, 
# read S and A and continue by pressing ENTER
done 
done

4. did my final recognition for all my saved screenshots with the best
combination of A and S, cant remember them

By the end, I had a 98% characters recognized, bad for passwords.
Neither tesseract nor Ocrad offered good results for me. In your case,
maybe tesseract would be helpful. Also unpaper.
