I wonder if there is a way to view .ps files without downloading/saving them while one using the Google chrome?
There is currently no way to view .ps (PostScript) files in Google Chrome.
I can imagine two ways to get the desired result though:
Convert the postscript file to PDF with some third-party utility and use Chrome's built-in PDF Viewer (or the PDF.js PDF Viewer Chrome extension) to display the PDF file. (this is relatively easy and can be implemented as a Chrome extension)
Implement a PostScript parser, and integrate it in PDF.js.
Specification: http://wwwimages.adobe.com/content/dam/Adobe/en/devnet/postscript/pdfs/PLRM.pdf
Limited proof of concept: http://logand.com/sw/wps/
Feature request on PDF.js issue tracker: https://github.com/mozilla/pdf.js/issues/1594 (this is closed, but if you deliver a high-quality patch, the patch may be accepted).
I compiled GhostScript 9.26 in Web Assembly and wrote a small wrapper to allow direct display of PostScript files in Chrome. You can find it here:
https://chrome.google.com/webstore/detail/ps-wasm/ebpiondkhkldijolgmhfenknngkkjola
You may try to use another open source browser. For example, the 2018_12 up-to-date openSUSE package collection version of the
http://www.seamonkey-project.org/
opens the .ps file in an external program in 2 clicks:
click displays the ps-file as "source code"
the "source code" view has a button titled "Open in External Program..." and after clicking that button the default .ps viewer application is launched.
At the time of the writing of this comment, the SeaMonkey web browser also supports the various old-school Java applets. A page with a Java applet:

The SeaMonkey also has a WYSIWYG-HTML-Editor, which unfortunately generates the pre-HTML5 HTML, but for users with non-IT-background it can still be very helpful as a static web site based document creation tool.
Thank You for reading my comment.

I'm teaching a Year7 class via Zoom on writing HTML, and I have one student on an iPad (the rest are on desktops/laptops), and they're not able to get their webpage to open in Safari (I'm using Chrome on Windows, which of course is simply a matter of double-clicking on the file). I'm trying to see what she sees, but I think Zoom is possibly not showing me the pop-up dialogues. She is using Notes to write the page (which looked to be the closest iOS equivalent to Notepad).
I Googled and sent her a few blogs, but still not working. I said she needs to click on Share and look for something like "copy path to file" or "copy link", and then paste that into the Safari address bar. She said when she did that Safari was showing the source code, not the rendered page. When she just taps the file it opens in Notes, not Safari. That made me suspect her file was actually index.html.txt (she tells me she has extensions switched on), but when I sent her my own file, which is definitely only index.html, she says the same thing is happenning.
Is anyone able to give me some definite step-by-step instructions (this is for a Year 7 student) on how to open their local HTML page in Safari?
thanks,
Donald.
Safari iPad no longer supports access to local or iCloud files. A number of iPadOS apps will however allow a user to view, edit, and test html code in files stored in local iPad, iCloud, or third party (e.g. Google or Dropbox) storage folders. One needs only to search in the App Store for “html editor” to see the list. Some of the apps have features that rival or exceed those found in tools on desktop (laptop) systems.
I had the same issue today on ios15.
There is a free app called Koder available on the App Store which will let you edit and view the HTML file. I’m no expert but the editor looks pretty fully featured at first glance.
Sorry to say but an iPad is obviously not the best place for simple HTML editing. At least not with the default apps available on iOS.
Given an existing HTML File one can use Files app to navigate to it and open it with double click. This will open the file in a very simple viewer wich is at least able to render the HTML. As a developer i bet its using WKWebView which is basically Safari's HTML View.
Turns out Microsoft Edge, unlike Safari, can still open local html files. Discovered in this answer. To wit:
Install Microsoft Edge from the App Store
Open Files (or whatever file browsing app you like).
Open the file, then tap the Share button to send to another app.
Scroll across to "More...", choose Edge, and voila!
Trying to embed a pdf on my website like so:
<iframe src="filename.pdf" type='application/pdf' frameborder="0"></iframe>
The website is a rails site, and currently I'm only running it on a local server.
The problem is that the pdfs render with a toolbar on top and a sidebar with my adobe creative cloud account information, as seen in the picture below (the actual content of the pdf displays in the white box under the toolbar and to the left of the sidebar)
How can I get the pdf to render alone, without the menu and sidebar?
If you allow the browser to choose how the PDF gets rendered, you're never going to be able to create a consistent experience for your users unless you are in a controlled desktop environment.
If you are looking for a consistent experience, use pdf.js to render the PDF in the browser.
If you are in a controlled environment and all of your users have a browser/viewer combination that will let the browser show PDF using the Adobe Reader plugin (as your screen shot shows) then you can use the "open parameters" at the end of the URL to control what gets shown. See the documentation at the link below.
http://www.adobe.com/content/dam/Adobe/en/devnet/acrobat/pdfs/pdf_open_parameters.pdf
That said, don't count on that solution to work for very long. Most modern browsers are not allowing the viewer plugins to function anymore and the rest are moving in that direction.

I think it's better use some kind of JS stuff just in case of cross-browser issues, like related into first link. Solutions like https://pdfobject.com/ it's helpful to get the job done. Look:
PDFObject 2.0 detects browser support for inline/embedded PDFs. (In
case you were wondering, your browser supports embedded PDFs. You
lucky dog, you!)
If you're working with dynamic HTML, such as a single-page web app,
you may need to insert PDFs on-the-fly. However, PDF embedding is not
supported by certain browsers. If you insert markup without first
checking for PDF support, you could wind up with missing content or a
broken UI.
The PDFObject utility helps you avoid these situations by detecting
support for PDF embedding in the browser; if embedding is supported,
the PDF is embedded. If embedding is NOT supported by the browser, the
PDF will NOT be embedded.
By default, PDFObject 2.0 inserts a fallback link to the PDF when the
browser does not support inline PDFs. This ensures your users always
have access to your PDF, and is designed to help you write less code.
The fallback link can be customized, or the option can be disabled if
you prefer.
PDFObject 2.0 is npm-ready. Modern web apps use npm to manage packages
and dependencies. PDFObject 2.0 is registered with Node Package
Manager (npm) and can be loaded dynamically.
PDFObject also makes it easy to specify Adobe's proprietary "PDF Open
Parameters". (Be warned these parameters are only supported by Adobe
Reader, most PDF readers will ignore the parameters, including the
built-in PDF readers in Chrome, Internet Explorer, and Safari. Read
more below.)
I have page where RSS icon is present. I want that when user clicks on RSS icon it will check in chrome browser that, whether that RSS reader chrome extension is installed or not
I am trying to achieve this by using chrome extension methods, mentioned here.
I tried something like this but it is not working:
var port = chrome.extension.connect("nlbjncdgjeocebhnmkbbbdekmmmcbfjd");
To use this API you need to be either an extension or a web application having the necessary permissions - normal web pages cannot access it. However, detecting whether an extension is installed in Chrome is still easy:
<script src="chrome-extension://nlbjncdgjeocebhnmkbbbdekmmmcbfjd/manifest.json"
onload="alert('installed')" onerror="alert('not installed')"></script>
This uses the fact that the extension's manifest.json file is located under a predictable URL and that web pages are allowed to load this URL. Of course, this isn't an officially documented approach but rather a loophole and a privacy issue. So be prepared for it to stop working in some future Chrome version. At the moment it works however.
Early on I was doing some debugging and testing using the chrome dev tools(known as inspect element). I found out that on the Resources column of the dev tool, Chrome can always access the resources from the server and display them(links, videos, images....). Just wonder how Chrome does that. Is there any way to write a piece of code doing the same thing(access the server resources of other websites, not modifying them but displaying, stuff like, the link of the video currently playing on the website, which usually does not pop up until the play button is hit)?
DevTools doesn't fetch resources from a site. It fetches them from the browser.
There were similar questions already
How does webkit/chrome's WebInspector Resources Inspection work?
and
Getting Information from Google Chrome's Developer Tools
The Chrome Developer Tools has two parts frontend (html+javascript) and backend (C++) and there is an API which specifies the protocol between these parts. You can see the specification here. You can use it for writing your own app instead of standard DevTools frontend.
Also there is experimental debugging API for chrome extensions.
I think the Webkit WebInspector go over the hole source code and match all resources of the source.
So it match <link href="something.css"> and then it place something.css in the resource panel under stylesheets. And exactly the same thing for the other tags.
It's not hard to make regexes for this.
Is there any way to communicate between my .exe application and Firefox?
Because, I have my own webpage. I'm using FireFox to browse it.
I have an application (in c++) to process a piece of HTML code from my webpage within FireFox. My application can print something directly to printer (raw print).
Since now, I coudn't access firefox's DOM content (page HTML source) from outside firefox; Also, I coudn't print directly to printer (raw print) from firefox.
Now, I'm looking solution for this problem. Here are my possibilities:
1.) My web page I can copy my related text to clipboard.
2.) My web page I can write my related text to Firefox's cookie.
3.) My web page I can write my related text to a file from client's PC.
4.) Any other way to send my related text to my .exe application.
But I don't know how can I do:
How can I copy to clipboard within firefox,
How can I read FireFox's cookie from my .exe application,
How can I create file in client's PC.
Is there any way to communicate between my .exe application (in c++) and Firefox?
You have to write an extension for firefox an use its API. For example see nsIProcess:
"The nsIProcess interface represents an executable process."
Assuming that your page has a true URL outside of FireFox, you could solve your problem by registering a custom protocol handler. E.g. register "X-myprettyprinter". Then, in FireFox, from http://www.example.com/index.html you can redirect to X-myprettyprinter:http%2D%2Dwww.example.com/index.html. FireFox doesn't know how to handle the X-myprettyprinter protocol so it hands off the URL to the OS, which then hands it to your registered application. Bonus: it works for all browsers. Downside: you have to retrieve the URL yourself and render the page again in-process
You could write an addon for firefox that allowed some form of integration with your application.
Here is a tutorial on writing firefox addins.
The best way to do this is to skip the .exe application and just make an ad on for FireFox, Take a look at the FireBug ad-on. It can pull certain codes out of a web page, If you use the API I bet you could do what your .exe program should.
