Exemple : in a day date textbox (dd/mm/aaaa), seize "11", keypress "tab" to focus on the month date textbox, keypress "Shift + Tab" to focus back to the day date textbox, keypress right or left arrow and "1" : The result is "111" in a textbox which maxlength=2 !!? Reproducible: Always Steps to Reproduce: 1.in a day date textbox (dd/mm/aaaa), seize "11", 2.keypress "tab" to focus on the month date textbox, 3.keypress "Shift + Tab" to focus back to the day date textbox, 4.keypress right or left arrow and "1" Actual Results: The result is "111" in a textbox which maxlength=2 !!? Expected Results: HELP URGENTLY :-) If there's a maxlength on a textbox, FireFox should block the number of caracter in each case...

Could you test this with Firefox1.5beta2?
