Is it possible to have an audio file played whenever the blank screen feature is used (by pressing b) during presentation mode? It would be useful to me if it were.--Leon (talk) 14:53, 21 November 2017 (UTC)

Firefox Photon/Quantom About:Config and CSS tweaks
Hi all. I've been playing around with getting back all of my appearance and settings from prior Firefox versions--especially the stuff I invoked with classic theme restorer. If you don't know, the new Firefox 57 "Photon" with its new "Quantum" engine, has made most prior Firefox's add-ons obsolete and incompatible (including classic theme restorer). For the benefit of others, not you experts, I've got back a lot of my functionality (including tabs on bottom) with CSS tweaks, which I learned last night through this page: https://github.com/Aris-t2/CustomCSSforFx

To my question. I was wondering if there's way either with CSS, or with about:config settings, to alter the appearance of the url bar, which I find quite clutterred in the new Firefox with things I don't need. What I am seeing is a huge amount of space being eaten up by the name of the website owner. That is, for example when I go to the url that I just provided above, for the Github CSS tweaks page, my address bar has three icons, followed by the full name of the corporation just before the url field. That is it has:
 * Icon 1: a globe which, when I hover, says it's for "Show site information";
 * Icon 2: a shiled which, when I hover, says it's for "Tracking attempts blocked..."; and
 * Icon 3: a lock which, when I hover, says the site is "Verified by: Name".

Following these three icons it says the full name: "Github, Inc. (US)"—all before the url address field starts.
 * I'd love to remove all three icons; don't need these notifications, and especially: I'd like to remove the name of the company. This is happening everywhere for me. Another example: when I go to Firefox's website, before the URL field it says "Mozilla Corporation (US)".
 * Anyone know of an About:Config or CSS way to remove any of this?

While I'm here, I'd also like to remove the two icons on the other side the end of the URL field as well (these appear in the field, unlike the ones before). First, there's three dots in a row *** (but centered vertically), which is for invoking a dropdown for "Page actions", and then I have a yellow star Bookmark this page icon. I'd love to remove those too. Thanks--212.92.124.51 (talk) 19:33, 21 November 2017 (UTC)
 * Reporting my progress in looking for solutions. I found a lead here: https://support.mozilla.org/en-US/questions/1061161#answer-726253 for the issue of removing the name of the company from the address bar. According to this, you can either add

or display: none !important; } to userChrome.css. Both work for the intended effect, except that, for whatever reasons, doing either invalidates all my other CSS tweaks, such as tabs on bottom, so it's no solution.--185.77.248.4 (talk) 00:20, 22 November 2017 (UTC)
 * 1) identity-icon-labels { display: none !important; }
 * 1) identity-box *:not(#page-proxy-favicon) {
 * All  directives must come first in a .css file. So, if you placed the last code sample into your userChrome.css, which came from CustomCSSforFx, before   directives they all will be ignored. Ruslik_ Zero  12:16, 22 November 2017 (UTC)
