[Linux] Separators don't show up in vertical toolbar about verticaltoolbar

[gomita]

It seems to be a problem only with Linux.
Now I have no Linux environment to test, so please test the following code, which you should add your userChrome.css file.

#vertical-toolbar[defaulttheme="Lin"] toolbarseparator {
    -moz-appearance: none !important;
    margin: 0.2em 2px;
    border-bottom: 1px solid ThreeDHighlight;
    border-top: 1px solid ThreeDShadow;
    height: 2px;
    border-left: none;
    border-right: none;
}

Note that this is only for test purpose, so please don't forget remove after testing.

Closer, but it doesn't quite work: it now leaves a very small invisible space where the separators are. I tried tweaking the borders, but that didn't get the separators to show.

Commenting out -moz-appearance: none !important; and changing the height to height: 20px; gets them to display vertically:

Not sure how to get the separator to expand horizontally though. Adding width: 50px; has no effect.

Thanks.
Then, please add the following line:

#vertical-toolbar[defaulttheme="Lin"] {
    -moz-box-align: stretch;
}

No effect, unfortunately.

Confirming that it works now. Thanks for the prompt fix.
