How to implement menu in firefox?

Question

css

Greetings!
Guys, I ran into the following problem:

<ul class="my-menu">
<div class="btn-group" role="group" aria-label="...">
<li><button type="button" class="btn btn-success menu-button"><a href="/">Главная</a></button></li>
<li><button type="button" class="btn btn-success menu-button"><a href="/trotuarna-plitka/">Тротуарная плитка</a></button></li>
<li><button type="button" class="btn btn-success menu-button"><a href="/border/">Бордюр</a></button></li>
<li><button type="button" class="btn btn-success menu-button"><a href="/shlakoblock/">Шлакоблок</a></button></li>
<li><button type="button" class="btn btn-success menu-button"><a href="/cement/">Цемент</a></button></li>
<li><button type="button" class="btn btn-success menu-button"><a href="/shifer/">Шифер</a></button></li>
<li><button type="button" class="btn btn-success menu-button"><a href="/truba-azbocement/">Труба асбестоцементная</a></button></li>
<li><button type="button" class="btn btn-success menu-button"><a href="/sipuchi-materiali/">Сыпучие материалы</a></button></li>    
</div></ul>

.menu-button{
    background-color: #379037;
    text-transform: uppercase;
    border: 1px solid transparent;
    border-radius: 2px;
}

.menu-button:hover{
    background-color: #2d7c2d;
    text-transform: uppercase;
    border: 1px solid transparent;
    border-radius: 2px;
}
ul.my-menu,
ul.my-menu li {
 list-style: none;
 padding: 0;
 margin: 0;
}

ul.my-menu li {
 float: left;
}
ul.my-menu li  {
 display: block;
 background: #449d44;
 text-decoration: none;
}

/*добавочный класс для текущего(выбранного) пункта*/
ul.my-menu li .current {
    padding: 4px;
    border: 1px solid rgba(255, 255, 255, 0.6);
    border-radius: 1px;
}

The rest of the styles are bootstrap.
In google chrome, this menu works. In firefox, no.
What could be the problem?
Thank you.

Answer 1

the problem is the lack of knowledge
downloaded bootstrap - and you are a programmer!
Why did you put the link in the button, radish?

Answer 2

I think the problem is somewhere in the layout or styles.
