See attached code below for demonstation of bug.
Explanation in code:

<div style="width:40%; background-color:#D4DDFF; margin:0; padding:20px 20px;
text-align:left; overflow:hidden; font-family:arial,sans-serif;"> <!--
height:auto; this div is for controlling padding in an easy way -->
1. Make the DIV container smaller by making the viewport smaller.<br><br>
Why does overflow:hidden / overflow:auto cause extra padding at bottom of the
DIV when values are assigned to either padding-left or padding-right.
<br><br>
The extra "padding" at bottom gets bigger if you make the div smaller.<br><br>
If you remove overflow:hidden / overflow:auto then the extra space at bottom is
gone.
Or if you remove padding-left and padding-right, extra space is also
gone.....<br><br>
Combination of overflow:hidden / overflow:auto and padding-left / padding-right
provokes this bug.<br><br>
Have just seen this bug in FF.... Tested in FF 1.0.6 and FF 1.0.5 with same result.

Reproducible: Always

Steps to Reproduce:
1. Create a DIV
2. Add both padding-left / padding-right
   Note: Have not tested with onlo one of them active.
3. Add overflow:hidden or overflow:auto
4. It is the combination of padding-right / padding-left and overflow:hidden /
overflow auto that triggers this bug.

Actual Results:  
Extra space "padding" are added at bottom of DIV

Expected Results:  
No extra "padding" or space should have been added to bottom of DIV
Note:

Have found that same bug applies for the SPAN tag as well. 
I would guess some other tags would have the same problem as well, but I do not
have the time to test them all.

Hope you mozilla guys can fix this in the next release.

Keep up the good work

I can see the bug in Mozilla1.7, but not in the latest nightly trunk build.
Reporter, could you please test with the nightly trunk build?

Could reproduce with Firefox 1.0.x, so this has most probably been fixed. Please
test with trunk bulds when it comes to layout issues. Firefox 1.0.x is based on
the rendering engine gecko 1.7 that is over one year old by now. Thanks
