CSS-styling on my form doesn't work on Firefox - html

Question

I have this login form, which works and looks just fine in Chrome, IE11 and Edge but when try it out on Firefox, it looks completely different;
My labels are not the same width, so I have to re-adjust them. Also, my submit button doesn't seem to take on styles.
How can I make this work with Firefox as well?
My HTML:
<div class="loginheader">تسجيل الدخول</div>
<div class="loginform">
<form action="login.php" method="post" name="myform" id="myform">
<p>
<label for="loginform">اسم المستخدم</label>
<input type="text" name="username" id="login" value="mohammed.nasyia#gmail.com" placeholder="اسم المستخدم" />
</p>
<p>
<label for="loginform">كلمة المرور</label>
<input type="password" name="password" id="password" value="mohammed.nasyia#gmail.com" placeholder="كلمة المرور" />
</p>
<p >
<input type="submit" name="submit" value="تسجيل الدخول" class="button admin-login-button"/>
</p>
</form>
</div>
<div class="loginfooter">
تسجيل الدخول كممتحن
</div>
</div>

Answer 1

I removed the floats (with a typo), set the margin to left on the .admin-login-button. I also added a media query for smaller screens.

}
#media screen and (max-width: 540px) {
input[type=text], input[type=password] {
width: 90%;
}
}
Seems to work in both Safari and Firefox.
