Firefox overriding style of html select option
Please try this code
/* FIREFOX FIX OF UGLY SELECT BOXES */
@supports (-moz-appearance:none) {
select
{
-moz-appearance:none !important;
background: transparent url('data:image/gif;base64,R0lGODlhBgAGAKEDAFVVVX9/f9TU1CgmNyH5BAEKAAMALAAAAAAGAAYAAAIODA4hCDKWxlhNvmCnGwUAOw==') right center no-repeat !important;
background-position: calc(100% - 5px) center !important;
}
}

Ok, so the solution here is to disable -> Multiprocess Windows
type about:config in the browser
then search for browser.tabs.remote.autostart (mine had a browser.tabs.remote.autostart.2)
change this to FALSE then restart the browser this will make firefox run Multiprocess Windows disabled which fixes the issue
This appears to be a bug that appeared since the release of multi-process Firefox. More info about Electrolysis here: https://wiki.mozilla.org/Electrolysis
If you're using Firefox 48 or later, you might be using e10s already. Check about:support and look for a number higher than 0 in the "Multiprocess Windows" entry.
Chances are: the computers affected are due to Multiprocess being enabled. This issue is being tracked on Bugzilla: https://bugzilla.mozilla.org/show_bug.cgi?id=910022
The issue should resolve itself with the release of Firefox 54.
