My draft webpage currently has a <head> but no <body>. It links to a css stylesheet that exists in the expected location but is currently blank. When I loaded it into Firefox 17.0.1 for Win XP, the error console returned these three messages:

Could not read chrome manifest 'file:///C:/Program%20Files/Mozilla%20Firefox/extensions/%7B972ce4c6-7e08-4474-a285-3208198ce6fd%7D/chrome.manifest'.

Timestamp: 07/01/2013 4:26:25 PM
Warning: XUL box for _moz_generated_content_after element contained an inline #text child, forcing all its children to be wrapped in a block.
Source File: chrome://browser/content/browser.xul
Line: 0

Direct3D 9 DeviceManager Initialized Succesfully.
Driver: nv4_disp.dll
Description: NVIDIA GeForce 8400GS
Version: 6.14.13.681

Can someone help me interpret the messages so I understand what they mean?

Short, practical summary for the three console lines and what they mean for the page code posted by .

The "Could not read chrome manifest … {972ce4c6‑…}" message comes from Firefox scanning its own extensions/themes, not from the HTML/CSS being loaded. That GUID is the built‑in theme ID and the warning is commonly benign — it just means a chrome.manifest wasn’t found or readable in that extension path and can usually be ignored unless an add‑on actually fails to work. (stackoverflow.com)

The "XUL box for _moz_generated_content_after … inline #text child" warning is emitted by Firefox’s UI/layout code (XUL) when it encounters inline text where it expects block children, so it forces an anonymous block around them. Typical web causes are invalid markup (for example, placing a block element inside a <p>) or CSS that relies on legacy Mozilla-only box types. Practical steps: validate the page with an HTML validator, remove block-level tags nested inside paragraphs, and avoid or replace legacy -moz-inline-box rules with modern equivalents (inline-block/flex) when possible. These warnings are usually harmless but can point to markup/CSS that should be fixed. (bugzilla.mozilla.org)

The "Direct3D 9 DeviceManager Initialized Successfully" line is an informational GPU/graphics backend log (driver name and version shown). It reports that Firefox initialized Direct3D for hardware acceleration; it’s not an error. If visual glitches are seen, updating the GPU driver or temporarily disabling hardware acceleration in Firefox can help; to confirm whether console messages come from the browser or extensions, run Firefox in Safe Mode or a fresh profile. (bugzilla.mozilla.org)

Quick checklist (applies to the thread): validate markup, remove block elements from inside paragraphs, test with a clean profile or Safe Mode, and treat those three console lines as mostly browser/internal logs rather than proof of broken page code. As noted, some of these messages have long histories; as pointed out, cleaning up HTML/CSS will reduce spurious layout warnings.

I read the bug discussion and it makes Mozilla sound like some sleepy-eyed bureaucracy. What I'll probably do is abandon Firefox and switch to Chrome as my Windows browser. In Linux I'll just find a non-Mozilla browser to use. I'm really, really disappointed in what I just read through the link trail you provided me. But at least it's not a problem with my code, just with organizational ossification, which the open-source community doesn't appear to be immune from.

I had been a big fan of the open-source concept but am starting to wonder whether it has lost its way. This isn't the first time I've found some troubling occurrences within open-source subcommunities.

need help interpreting error messages

Can you post your code? Including the CSS code that included this: element contained an inline #text child.

You have to understand some CSS code won't work correctly in some browser you need to find a way to adapt to it.

Sure, I'll post the code. In fact, I'll just upload it. (The image file is missing from this upload and I wasn't allowed to upload a .css file so it's a .txt copy).

			<h1>Coding and Creativity Plans and Dreams</h1>

			<img src="webimage.png" />

			<p>Welcome to the humble website of a retired middle-aged fellow who passes the time learning
			   programming and writing fiction. This website will eventually feature Javascript games,
			   downloadable Python programs, short stories and poems, as well as other pleasant things.
			   Right now it's somewhat under construction as I get my coding skills up to speed. The
			   following is a summary of my plans for the website and a little bit about me.</p>

			<h3>Website Design</h3>

			<p>I am teaching myself HTML and CSS. So far, I've learned enough to design this webpage using 
			   only a text editor rather than any graphical tools. I am hoping to take
			   advantage of the power and versatility of from-scratch website design to make superior
			   webpages you can't make with the graphical tools normally available for download or provided
			   by a webhost. <strong><em>Automation is limitation.</em></strong> Anyone who uses a graphical 
			   design tool will necessarily be limited in what she can do. I want to transcend those limits. 
			   My shortfall in visual creativity will be an obstacle, since all my creativity has to do with 
			   words, but I'm hoping to run into visually talented people with their own shortfall in 
			   technical knowledge who will want my help in making their vision of a website come alive.</p>

			<h3>Other Programming</h3>

			<p>I'm also teaching myself Javascript and Python. So far, I've written <em>The Extremely Long
			   Compliance Quiz (TELCOQ)</em>, which takes <strong>f.o.r.e.v.e.r.</strong> to tell you whether 
			   you're any good at following instructions, and am working on <em>Eyetee's One-Handed Blackjack 
			   Game (EOBLAG)</em>, which you should avoid if one-handed play is against your religion. Those 
			   will be available eventually as Javascript games you can play right on this website, and later 
			   as Python games you can download to your device. There are other programs in the works, 
			   including the star of the show, <em>Eyetee's Spiritual Journey (EYSPIJ)</em>, which has some 
			   commercial possibilities and will take some time to get off the ground. Stay tuned.</p>

I assume you are using HTML5? Most function doesn't work well on some browsers.

First of all you didn't put a close </body> </html> on the bottom of your code.

So this is your code that I edit a little:

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Eyetee's Coding and Creativity Site</title>
<meta name="keywords" content="Miki-Kocic, Eyetee, IT, computer, website, webdesign, design, writing, creative-writing, fiction, story, stories, short-story, short-stories, html, 
css, programming, javascript, computer-code, game, app, apps" />
<meta name="description" content="Javascript games, short stories and more" />
<meta name="author" content="Miki Kocic" />
<link type="text/css" rel="stylesheet" href="stylesheet.css" />
</head>
<body>
<h1>Coding and Creativity Plans and Dreams</h1>
<img src="webimage.png" />
<p></p>
<h3></h3>
<p></p>
<h3></h3>
<p></p>
<div></div>
</body>
</html>

Second your CSS doesn't have this @charset "UTF-8"; .There's nothing wrong with your CSS code at all maybe this p div I never seen that one but since you are HTML5 you need to put @charset "UTF-8"; on top of your CSS

Read it more here:

https://developer.mozilla.org/en-US/docs/CSS/@charset

This is your CSS

@charset "UTF-8";
body {background-color: #2f4f4f;}
h1 {font-family: cursive;font-size: 2.5em;color: #ff8c00;background-color: #fff8dc;margin: auto;text-align: center;border: 1px solid black;border-radius: 12px;padding-bottom: 7px; margin-bottom: 35px;}
h3 {font-family: cursive;font-size: 2em;color: #ff8c00;background-color: #fff8dc;margin: auto;text-align: center;border: 1px solid black;border-radius: 12px;padding-bottom: 7px;}
p {font-family: sans-serif;font-size: 1.2em;color: yellow;text-align: left;border: 1px solid white;border-radius: 8px;padding: 4px;margin-bottom: 35px;}
img {height: 200px;width: 100%;margin: auto;text-align: center;border: 1px solid black;border-radius: 30px;}
div {color: orange;font-family: cursive;font-size: 0.8em;}
p div {color: black;font-family:cursive;font-size: 1.2em;}

If most html 5 functions don't work well in some browsers, should I be using html 4.01 instead? It wouldn't be that difficult to recode the webpage to comply with 4.01.

The webpage isn't finished and I simply forgot to put in the closing body and html tags ahead of time, but thanks for the reminder.

The p div needs to be deleted because it was something I tried in order to use a <div> tag nested within a <p> tag in order to change text style through the separate stylesheet instead of using html tags within the text. I'll get rid of it.

Thanks very much. Solved.

No, you can still used <!DOCTYPE html> for most CSS code too. As long you remember which CSS code can be used in <!DOCTYPE html>. Some CSS3 won't comply well in certain browsers so that's why you can mixed it up as long you can find a common ground for a certain CSS code then there shouldn't be any issue.
