What command-line utility renders HTML as Firefox would, creating a
static image, without actually running Firefox and xwd (or ScreenGrab,
etc)?
Since all of Firefox's rendering libraries are open source, I'm
assuming someone's written something like this? It would be very
useful.
I realize static images can't have Flash animation (animated GIF/PNG
notwithstanding), JavaScript, etc, so I'm just looking for something
that renders plain HTML.
html2ps is worth a try, although it does not seem to use the css style sheets. This is a serious limitation.
On Debian/Ubuntu, it is provided as a package, so the classical sudo apt-get install html2ps will be fine.
(I know this has been given in the comments, but for the future reader, I thought it might be easier to find as an answer.)
You could write a small script which simply runs firefox using the command line options does a screen-shot, then closes firefox. Should only be about 3 lines of code to get started.

I know no java or any other language besides c#, so how would I try to make it a popup chrome extension that you can play in your browser.
Maybe you can read this: https://developer.chrome.com/docs/extensions/mv3/getstarted/
I'm pretty sure that in Unity, you can build an application as WebGL. You can read this if you want: https://docs.unity3d.com/Manual/webgl-building.html
Then, you can put the code they give you for the WebGL and put it inside the extensions HTML, and then I think it'll work.
Have a requirement to print html or html from vb6 application using only firefox as we have already for IE. So, need command to print using firefox.exe.
Something like this firefox.exe -print http://www.google.com which is not working. Is there anyway to do this? Thanks for your help.
There is no built-in support for a -print command line switch. See this document for the different command line switches supported for the Firefox browser. Support for such functionality would most probably have to be implemented through an extension.
If no extension exists that currently offers what your looking for, a Google search yielded this mozillaZine forum thread: "Printing to file from Commandline?" You could have a look at the discussion, or download and modify the referenced add-on from the source link.
Or else, you could always create your own application (probably not in VB6) by embedding the Gecko layout, but since the Mozilla killed the embedding API a while back, you'll have a lot of integration work to do (or else you could go with another layout engine like Webkit).
You can use the built in webbrowser control to print html via IE: http://www.vbforums.com/showthread.php?384076-Webbrowser-Control-Tip-and-Examples
If you must use firefox, there was a firefox active x control but I have not used it and dont know the status:
mozilla firefox activeX
or

It also looks like there is a webkit floating around online (google it)
Does Sublime Text support live editing of files?
I'm looking for a better workflow. I really like Sublime Text, but recently I've been spoiled by the "Live Editing" capabilites of tools like Codepen.io and (recently tested) Adobe Brackets. When I go back to Sublime, even Live Reload seems clunky in comparision.
Live Reload: Press Save To Preview..
I'm using the LiveReload Chrome plugin, and depending on the project (Ruby or JS) I'll use Guard or Grunt to watch system files. I like LiveReload. But having to press 'save' on a file to see its changes in the browser is driving me nuts. Even with CSS style injection (no full browser reload), I'm flying blind in comparision to Codepen and Brackets which have instant updates as you type.
Other Tools
** GUI Tools **: I've heard of tools like Codekit and Hammer. Please correct me if I'm wrong, but they seem to do exactly what Gaurd and Grunt do—except no command line.
** Chome Tools Spaces **: The ability to edit Sass in the browser is cool. I've set this up, but I rarely use it. Editing HTML/CSS/Sass in Sublime Text is superior to Chrome Tools in every way. And to that point, it is far superior to Adobe Brackets which is why I don't (at this point) considering using it (Also it seems most of Brackets 'cool features' work on vanilla CSS, and not on Sass).
**Live Style: I've tried this, and I just can't get it to work.
I must have Googled "Live editing Sublime", "Live Refresh Codepen Sublime Text", etc.. a thousand times this year and results have been pretty lousy.
If anyone has any gems of information regard this to add to this PLEASE POST THEM!
Yes it does, all you need is takana: https://github.com/mechio/takana
This tool creates a little server which interacts in live the the loaded css of the page. All you need is to setup the server and add the javascript snippet to your html code (you will obviously remove it afterwards…).
For now only OSX, live editing is even working on different browsers. Welcome to the awesome!
Using shell_exec with Xvfb and FireFox currently to capture screen shots. However, need to download the entire html (e.g. Save Page As --> Web Page complete.) to a directory using shell_exec. Have looked at all the different option available in the Mozilla Developers Forums but have not been able to figure out how to do this.
This code appears to be what I might need but where and how is this implemented so it can be accessible in shell_exec?
var file = Components.classes["#mozilla.org/file/local;1"]
.createInstance(Components.interfaces.nsILocalFile);
file.initWithPath("C:\\filename.html");
var wbp = Components.classes['#mozilla.org/embedding/browser/nsWebBrowserPersist;1']
.createInstance(Components.interfaces.nsIWebBrowserPersist);
wbp.saveDocument(content.document, file, null, null, null, null);
The Above Code Source
void saveDocument(
in nsIDOMDocument aDocument,
in nsISupports aFile,
in nsISupports aDataPath,
in string aOutputContentType,
in unsigned long aEncodingFlags,
in unsigned long aWrapColumn
);
The Above Code Source
There is a Stackoverflow manual solution here but it does not address shell_exec:
How to save a webpage locally including pictures,etc
There are few options that I know of, but none that I know are fitting your question exactly..
Open firefox http://yoursite.com from shell, then send keystrokes to firefox using xte or similar method. (This is not headless mode though.)
Download using wget. It can work in recursive manner. Or alternately you can parse the HTML, if it is quite simple web page. If you need to submit form, use curl instead of wget.
Use greasemonkey addon & write a script, which would get loaded on http://some-fake-page.com/?download=http://yoursite.com & then open firefox with that fake-page url.
Develop your own firefox addon to do above work.
There may be other better options for this as well, but I don't know them.
I'm trying to load an image from the Firefox cache as the title suggests. I'm running Ubuntu, so the location of my cache is /home/me/.mozilla/firefox/xxxxxx.default/Cache
However, in the Cache (and this is on Mac, too) the filenames are just ridiculous combinations of letters and numbers. Is there a way to pinpoint a certain file?
You should take a look at the source code of the CacheViewer Add-on.
Download the file instead of installing it (right click and save as) and then extract it (it's just a Zip file, even though it has a .xpi extension), then extract the cacheviewer.jar file inside the resulting chrome folder. Finally go into content and then cacheviewer to find the javascript and XUL files.
From my brief investigation, the useful routines are in the cacheviewer.js file, though if you were hoping there would be a simple javascript one liner for accessing cached items you're probably going to be disappointed. The XUL files (which are just XML) are helpful in working out which JS functions are called to perform particular tasks. I'm not too sure how all this maps into Greasemonkey, rather than the extension environment, but hopefully there's enough code to get you started.
Ummm, that really is an internal implementation detail. But I suggest looking at how about:cache?device=disk and about:cache-entry?client=HTTP&sb=1&key=https://stackoverflow.com/Content/img/wmd/blockquote.png are implemented.
Also, http://www.securityfocus.com/infocus/1832 gives details, too. Note that Firefox doesn't use a separate file for everything...
And of course, Firefox may change the format at any time.
Just give your img src= attribute the full URL. If the image happens to be cacheable (the server sends an appropriate Expires: or Cache-control: header, for example) and it's already in the cache, Firefox will not hit the network.
HTTP caching is supposed to be invisible. When you're generating content, you generally shouldn't worry about it.
You can point REDbot at a URL to see all sorts of delicious information about its cacheability.
