Maybe I found a problem with the Firefox extension:
I want to create a password using the extension. To change the length of the password suggested by the extension I move the slider, but the password doesn't change. Also the other two sliders (Digits, Symbols) have no effect.
The password is being updated though when I chech and uncheck the "Pronouceable"-Checkbox.
I'm using 1PW 3.8.11 (build 31205), Firefox 8.0.1 and Mac OS X 10.7.2. Restarting Firefox didn't solve the problem.
PS: Maybe the same problem like in this post? http://forum.agilebits.com/index.php?/topic/9587-firefox-81-1p-browserextension-trouble/
