```
.ui_btn , .sub_txt {
margin: 2px 0px 2px 3px;
background:#181c18;
cursor: pointer;
display: inline-block;
text-align: center;
text-decoration: none;
text-transform:lowercase;
}

.ui_btn input, .sub_txt input , .disabled input{
border-spacing: 0px; 
background: none;
color: #fff;
outline:0!important;
margin:0!important;
cursor: pointer;
display: inline-block;
font-weight: bold;
border: 1px solid #181c18;
font-family: Arial, sans-serif;
font-size: 11px;
padding: 7px 6px!important;
white-space: nowrap;
text-transform:lowercase;
line-height: 12px!important;
}

```

And this is my button:

```
<label id="SD_mrs_t" class="ui_btn" for="SD_mrs">
<input id="SD_mrs" value="More Specific" type="button"/>
</label>

```

As a result button in Firefox has something like:

```
padding: 9px 8px!important;

```

Is there any solution without definition of special parameters for Mozilla browser?
