How to fix indentation in mozilla?

Question

Browsers

Crossbrowsing problem.
There is an input for a subscription in which the button is absolutely positioned and aligned. In mozilla it is displayed normally, in chrome, opera and ie from the bottom indent. If you increase the padding, it becomes normal, but in the mosaic it crawls out by one pixel. Can you please tell me how to fix it in mozilla?

I don’t know how much of a crutch, but with this option there seems to be no problems added 3 lines at the end

footer .wrapper .container .email .cover label a {
    text-decoration: none;
    font-weight: bold;
    font-size: 16px;
    border-radius: 0 50px 50px 0;
    background: #0189ce;
    color: #fff;
    padding: 6px 20px 6px 20px;
    -webkit-box-sizing: border-box;
    box-sizing: border-box;
    display: block;
    position: absolute;
    right: -20px;
    top: 0;
    height: 35px;
    padding: 0 20px;
    line-height: 35px;
}
