Is it possible to to create an <a> tag that links to a particular resource such as an image or PDF and when the user clicks it, it will open in Windows Preview, Adobe Reader etc (whatever the default program is for that filetype) by using only a URL scheme or something like that?
It is not possible using <a> tag to specify opening of an image to be opened up using Windows Preview (not aware of any such plugin). you can integrate picasa though (there is a plugin for major browsers). Same for the adobe pdf plugin.
I guess you want it for your users. and you cannot be sure if all users have the plugins installed, I guess that is why you asked by "...using only a URL scheme or something like that". But I am afraid there is no such facility for <a> tag.

I'd like to show several webpages in one Chrome window by either writing an app or an extension.
Genuine iframes won't do, because some webpages either disable loading in iframes, or otherwise problems with content-security-policy directives prevent this from working.
webview tags don't use the browser's extension set, or write to history and so on - they seem to be just kind of little browsers of their own.
App Windows would be nice if instead of having their own window, they could be embedded in a single host window.
What I'd like is several "iframe-like" components that act completely like a normal Chrome viewport from the loaded site's perspective, and upon which installed extensions work, etc. If I were able to install extensions inside a webview, that would work too.
Is there anything like this that I can use within a Chrome app or extension?
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.

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'm trying to link To a specific PDF page from MsOutlook'10 or MsWord'10, the #page=... anchor is particularly useful and works fine elsewhere. Unfortunately when I click [ctr-K] in Outlook or Winword, my links are re-formatted assuming a UNC path. The PDF file is located on a shared drive.
Using the "file:" prefix links will open a PDF in Adobe Reader (outside of the browser), and "http:" will open inside a browser. The issue is that I seem to need to open in a browser with the "file:" prefix in order for an anchor to work. I know the anchors work inside a browser. Outlook uses the Windows/Explorer Default Program (based on file extension) which always seems to open in Adobe Reader neglecting my anchor.
Is anyone aware of a solution, to link to a specific page or bookmark of a shared-PDF from a MS Outlook and/or winword link?

I made a button for a PDF download that is working well in Chrome but it doesn´t open in Mozilla.
This is the code I used:
<a target="_blank" href="http://gerster.com/docs/posamenten_neuheiten_2014_2.pdf">Jetzt PDF-Katalog herunterladen</a>
What could be wrong?
Note: No error is showing up.
Q Using window.open or "target=" such as blank it doesn´t open in ### Browser
What could be wrong?
It is up to each user to download or permit binary.PDF running in a browser viewport after download, this is especially true after download fron any non trusted site.
OOB many browsers assume they can sandbox the PDF download and then allow as default action review of the PDF file. Chromeium based browsers like Edge may be more inclined to use that before the user improves their security.
So the 1st task for a user should be to switch off Edge auto viewing of PDFs and switch to a more secure setting.
In that case Edge / Chrome and other browsers will NOT auto run the downloaded PDF but ask the user if they wish to View after Download or simply Download.
One of the possible values of that attribute is _blank, which tells the browser to open a new window (or tab, if that’s the user’s preference) when that link is clicked.
This used to be “invalid” in HTML
see A Bad Reason: The link is to a PDF
If you are going to do it, not only do you need the target attribute for the functionality, you need to rel attribute for security.
So do not open yourserver to security issues blacklist or pop-up blocking see https://mathiasbynens.github.io/rel-noopener/
Don’t use target=_blank (or any other target that opens a new navigation context), especially for links in user-generated content, unless you have a good reason
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.
