But when I want to browse any file in Mozila Firefox the file upload control does not work.

Here is my code.

ASP.NET

<td class="TableSix">
                                                <button type="button" class="TableThree" style="position: relative;">
                                                    <asp:FileUpload ID="btnGovt_Id_Upload" runat="server" placeholder="BROWSE" class="TableThree" Style="width: 100%; opacity: 0.0; color: #c4c4c4; position: absolute;" />
                                                    BROWSE</button></td>

I want to design the file upload control look like as a button with text as BROWSE.

It's not the fileupload that isn't working in Firefox, it is your attempts to style it and embed it that isn't working so your title is a little misleading.

Then you have to use fake controls.

So, hide the actual file upload control and on the other button click event, just click the file upload control dynamically using JavaScript/jQuery.

When you nest the control inside a <button>, that button receives the click, and does not pass it on to the invisible file upload control.

Try nesting it inside a <label> instead:
Whipping File Inputs Into Shape with Bootstrap 3 · A Beautiful Site[^]

HTML

<label class="btn btn-default btn-file">
    Browse <input type="file" style="display: none;">
</label>

CSS

.btn-file {
    position: relative;
    overflow: hidden;
}
.btn-file input[type=file] {
    position: absolute;
    top: 0;
    right: 0;
    min-width: 100%;
    min-height: 100%;
    font-size: 100px;
    text-align: right;
    filter: alpha(opacity=0);
    opacity: 0;
    outline: none;
    background: white;
    cursor: inherit;
    display: block;
}

Alternatively, use a pre-built plugin - for example: Bootstrap File Input[^]
