Firefox won't print inline SVG from external file - firefox

I cannot get Firefox to print an svg from an external file.
I have an icons.svg file with a lot of different icons. I embed them into the page using the following code:
<svg class="icon icon-sort">
<use xlink:href="/icons.svg#icon-sort"></use>
</svg>
My icons.svg looks like this:
<svg style="position: absolute; width: 0; height: 0;" width="0" height="0" version="1.1" xmlns="http://www.w3.org/2000/svg">
<defs>
<symbol id="icon-sort" viewBox="0 0 1024 1024">
<title>sort</title>
<path class="path1" d="M960 432h-896l448-432z"></path>
<path class="path2" d="M960 592h-896l448 432z"></path>
</symbol>
</defs>
</svg>
In Chrome, everything prints fine, in Firefox, it is blank. I am also using the svgxuse polyfill, but I have the same issues with and without it.
You can use the following link for an example, none of the SVG's print in Firefox:

I am using Firefox v50.

Clicking On-or-Through Image is Browser-Dependent

I have found a difference between how Firefox and Chrome handle clicking near an image that I need to fix. I have a rect with an image occupying roughly the top 65%. I preserve the aspect ratio of the image and so it appears narrower than the full rect, which is perfect for what I need.
However, when I click near to the image, in the margin space either side of it, Firefox says I have clicked on the rect whereas Chrome says that I have clicked on the image. Inspecting the elements, I see that the image element spans the full width of the rect in both cases, but it is the functionality in Firefox that I need (as though I'm clicking "through" those image margins).
This is better explained with an example. The code below shows one rect and a narrow image in the top 65%. If I click either side of the image in Firefox, it says that the event.target.nodeName is "use" (I have the rect in a <g>) whereas Chrome says it is "image".
function clickHandler(ev) {
ev = ev || window.event;
alert (ev.target.nodeName);
}
text {
text-anchor: middle;
font-size: 10px;
font-weight: bold;
font-family: "Times New Roman";
pointer-events: none;
}
.m {
stroke: dimgray;
stroke-opacity: 1.0;
stroke-width: 1.5;
fill-opacity: 1.0;
fill: white;
}
<svg id="TreeTest" xmlns="http://www.w3.org/2000/svg" version="1.1" xmlns:xlink="http://www.w3.org/1999/xlink">
<defs>
<g id="G-Box">

<g id="HenryProctor">

</use>
<text x="90" y="106" dy="1em">Henry</text>
<text x="90" y="106" dy="2em">Proctor</text>
<image x="52.5" y="52.5" width="75" height="51.5" xlink:href="https://parallaxviewpoint.com/Images/Proctor_Henry_b1833.jpg" preserveAspectRatio="xMidYMin meet" onclick="clickHandler(evt);">
</image>
</g>
</svg>
Is there a way to detect when the click was only on the visible part of the image?
[Edited for clarification] I need to distinguish between a click on the visible image and a click anywhere else in the rect. I have my event handler on both, but the action it takes depends on knowing what the user clicked on.
That difference is an interesting quirk that I hadn't noticed before.
Although Firefox's behaviour seems the most useful in this case, I think that Chrome's behaviour follows the spec more accurately. The blank areas on each side of the image are still technically part the "fill" of the <image> element. So clicking there probably should return the "image".
Do you care whether the user clicks on the visible part of the image, or the blank areas beside it? If not, then you could just tell the browser to ignore all click events on the <image> element using:
pointer-events="none"
Now when you click anywhere on the image, in Chrome, you get "use".
function clickHandler(ev) {
ev = ev || window.event;
alert (ev.target.nodeName);
}
text {
text-anchor: middle;
font-size: 10px;
font-weight: bold;
font-family: "Times New Roman";
pointer-events: none;
}
.m {
stroke: dimgray;
stroke-opacity: 1.0;
stroke-width: 1.5;
fill-opacity: 1.0;
fill: white;
}

SVG content is in shadowDOM, so you can use evt.composedPath() to get the whole Event path.
evt.composedPath()[0] is the Element you clicked.
SO snippets have some delay issues with this; outputting errors in the console, and after a minute the wrong info in the attached SO snippet console.
Update
Argh! OP wants IE support (its 2021, even Microsoft says not to use IE)
For those who want a modern solution with native Web Components, where the IMG is read, and its naturalWidth and naturalHeight are used to generate SVG from a Template

SVG textpath rendering appears reversed in Firefox

I'm trying to render text along a curved path in an SVG. It renders as expected in Chrome, Safari, and Edge, but it renders differently in Firefox.
jsfiddle: http://jsfiddle.net/hLyq1ug6/
<svg width="320" height="320" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" style="background: blue"><path d="m57.8,160 a102.2,102.2 0 1 1 204.4,0" fill="red" id="curvedTextPath5cf008a181659"></path><text x="160" y="185.5" style="fill: #ffffff; font-size: 35pt"><textPath xlink:href="#curvedTextPath5cf008a181659" startOffset="0" text-anchor="middle">Hello</textPath></text></svg>
Expected:
Firefox:
Per the SVG specification
When the inline-base direction is horizontal, then any ‘x’ attributes on ‘text’ or ‘tspan’ elements represent new absolute offsets along the path, thus providing explicit new values for startpoint-on-the-path.
It seems only Firefox does this correctly.
I've removed the x and the y attributes from the text. If you need to offset the text use startOffset="50%"I hope it helps.
<svg width="320" height="320" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" style="background: blue">
<path d="m57.8,160 a102.2,102.2 0 1 1 204.4,0" fill="red" id="curvedTextPath5cf008a181659"></path>
<text style="fill: #ffffff; font-size: 35pt">
<textPath xlink:href="#curvedTextPath5cf008a181659" startOffset="50%" text-anchor="middle">Hello</textPath>
</text>

SVG shows not correctly in Firefox browser

I have next svg object which shown well in Chrome and AI, but it shows not correctly in Firefox. In my svg i have 2 textPath tags, i try to set italic font-style for both of them however only 1 textPath effected. How can i fix it if i still want 2 textPath elements be in 1 svg object?

The problem seems to be that the font you selected, Carter One, has no italics variant. So the browser needs to use a fallback (which, as far as I know, amounts to skewing the glyphs). Firefox seems to fail with the simultanuous task of "inventing" an italics font, painting a stroke and writing it on a text path.
It is not a problem to use multiple textPath elements inside one text. Only when using both a non-zero stroke-width and font-style:italics a font with a known italics style needs to be referenced. For example Lato has one:

As an aside, while I don't know exactly which browsers support it, at least most modern browsers seem to know the paint-order CSS property, which removes the need to paint the text twice. paint-order:stroke paints the stroke below the fill:

Why does simple animation cause a very long update layer tree?

Paste this code on any site with a heavy interface (twitter for example) and run a performance test:
<div style="position: absolute; contain: strict; width: 100vw; height: 100vh; z-index: 2000; top: 0; left: 0; background: white; backface-visibility: hidden;">
<svg viewBox="0 0 100 100" height="40px">
<rect width="40" height="40" x="93.5319">
<animate attributeName="x" dur="1000ms" repeatCount="indefinite" from="0" to="100"></animate>
</rect>
</svg>
</div>
For incomprehensible reasons to me, the "update layer tree" takes several ms on the core i7 4770k:
example on twitter.com
And if you insert the same code on an empty page, then everything works very quickly. Why is this happening and how to fix it?

Svg doesn't show

I used this temaplte for my web. I edited it and it was be ok at my localhost. I uploaded it to hosting and arrows in .svg doesn't show. Here is source code:

Check that your webhost is returning the right MIME type for SVG. It should be "image/svg+xml".
You can check by looking at the request using the Network tab in Firebug or your browser developer tools.
