Confirmed, I can reproduce this issue on Firefox 53 on ubuntu/Mac OS X. But it works on Firefox 50 on ubuntu/Mac OS X.

I can show the checkbox after disable:

.nav-search .nav-category input[type="checkbox"] {
  background: 0
}

I think it's a regression issue. Switch to needsdiagnosis.

Cool find @MDTsai
Confirmed.

I filed a bug on Bugzilla. I will close as duplicate of https://bugzilla.mozilla.org/show_bug.cgi?id=1328474

Ah wait my test is incomplete.

[karlcow]

This is the real test.

[karlcow]

The rendering in WebKit.

[karlcow]

Yeah too quick.

.nav-search .nav-category input[type="checkbox"] {
    border:1px solid #ccc;
    background:0;
    -webkit-box-shadow:none;
    box-shadow:none;
    display:inline-block;
    margin:3px 5px 0 0;
    height:14px;
    padding:0;
    vertical-align:top;
    width:14px;
    -moz-appearance:none;
    -webkit-border-radius:3px;
    border-radius:3px;
}

There is no -webkit-appearance: none, but indeed the webkit. So it's really a regression.

Firefox 52, Firefox 53, Safari

Just to understand what the developer was expecting before Firefox changes. the issue arises because background is used to draw the checkmark.

[karlcow]

I wonder what they were trying to solve.

[karlcow]

I will reopen the issue and switch to needscontact.

Hmmm but maybe our Ebay contacts can't really help as Ebay is just a share holder.

eBay currently holds an 18.37% share in MercadoLibre with more than 50% of the board votes.

Oh but…
@mercadolibre exists.

Maybe someone like @dimartiro or @joaoandre can help us to find the right person there in the front-end team.
