Firefox tells user they need a plugin to display an embedded webpage - html

There's a section on my site where I display data from another site, using:
<embed src="URL"></embed>
I recently discovered that this works fine for most people, but that Firefox users get an error telling them they need to install a plugin. I searched around for a solution and people seemed to find that specifying the MIME type worked:
<embed type="text/html" src="URL"></embed>
But this isn't working. I can switch to iFrames, but I dislike how they display the information. Any other suggestions?

Per spec, embed elements are only handled via plug-ins or an SVG renderer (and in the latter case behave just like iframe).
You can do <object data="URL"></object>, but of course that will also behave like iframe...

I've been having the same issue with an html5 game. It appears that Firefox doesn't support if you want to embed an external html file. This tag should only be used for plugins.
https://developer.mozilla.org/en-US/docs/Web/HTML/Element/embed
To embed an external html file into another page in Firefox you have to use iframe or object tags instead. For the interactive nature of my external page I used iframe and it worked in IE / Chrome and FF, I had to make the margins larger than the game itself.

Embed PDF in mobile browsers

I have the code below which is a perfect solution to what I need, which would essentially be embedding any of JPG, GIF, PNG or PDF files in my webpages. It works perfectly in PC browsers, but a critical requirement for the pages is to have them compatible in mobile browsers due to its target users.
<iframe src="uploads/test1.pdf" width="auto" height="auto"> </iframe>
Although image files work fine, PDF files are opened separately in the mobile browser and not embedded inline in the web page. What would be an alternative solution or implementation to this?
You can use PDFJs library. Using just JS you can render pdf files.
Please , check here : https://mozilla.github.io/pdf.js/
One simple option is that the the object element provides a fallback, so you can do:
<object data='some.pdf'>
<p>Oops! Your browser doesn't support PDFs!</p>
<p>Download Instead</p>
</object>
Then, when the mobile browser can't get the item, it'll just show this and you'll be all set, kinda.
Here is my solution to this problem.
<object data="mypdf.pdf" type="application/pdf" frameborder="0" width="100%" height="600px" style="padding: 20px;">
<embed src="https://drive.google.com/file/d/1CRFdbp6uBDE-YKJFaqRm4uy9Z4wgMS7H/preview?usp=sharing" width="100%" height="600px"/>
</object>
Explanation:
<object> tag has a feature that when it is unable to load item, it loads the content inside itself i.e tag.
Since object tag cannot load on mobile view, therefore on mobile devices, embed tag will become active.
Q) Why can't we directly use tag for all cases?
You can actually, but since the embed tag is loading file from
drive, it does not gives any user controls for the pdf that we see
with object tag (zoom, page no., etc.). So our code will give the user pdf view controls atleast in the desktop mode instead of not giving any controls at all.
Q) Direct drive links don't work....so why this solution?
In the above google drive URL, view is changed to preview.
drive.google.com/file/d/1CRFdbp6uBDE-YKJFaqRm4uy9Z4wgMS7H/view?usp=sharing
becomes,
drive.google.com/file/d/1CRFdbp6uBDE-YKJFaqRm4uy9Z4wgMS7H/preview?usp=sharing
So, we can make direct drive links work with this little modification
Google Docs viewer offers a feature, that lets you embed PDF files and PowerPoint presentations on a web page.
<iframe src="https://docs.google.com/viewer?url=http://infolab.stanford.edu/pub/papers/google.pdf&embedded=true" style="width:100%; height:650px;" frameborder="0"></iframe>
replace the URL(http://infolab.stanford.edu/pub/papers/google.pdf) with your own address, It's worked for me but it takes more time to load on
src:http://googlesystem.blogspot.com/2009/09/embeddable-google-document-viewer.html?utm_source=pocket_mylist
The only way I have found, which allows you to embed pdf is using Google drive, then select the menu button once you have opened your file, and select get embed code, you can only use a Google drive or Google docs reference. And you must also turn public sharing on otherwise others won't be able to view it without permission.
Using Adobe PDF Embed API solved my problem.
Adobe PDF Embed API
I ran into the same issue. As a new developer, I wasn't aware that mobile browsers have issues embedding PDF files in iframes. I am now... lol
I racked my resources trying to get this to work when it dawned on me that mobile browsers do not have an issue displaying PNG files in a new window. So, in my infinite wisdom, I opened the PDF files in Gimp 2.0 then exported them as PNG files. And then I created buttons for the user to click and now it opens the graphic instead of trying to embed the PDF.
Looks like this:
<input class="AG" id="UnityBtn" type="button" value="Unity" onclick="location.href='../Meeting_Info/Unity.png'" />
I don't know if this is possible for you, but it worked beautifully for me.
Use an object tag with a iframe tag inside your object tags.
The object data can be a pdf or png file by changing the type and can use any link you want stored wherever, however the I frame is the one which will be loaded for mobiles which has to be a link from Google drive or Google docs you also need to allow the files to be shared public otherwise others won't be able to view them.
I would share the code but this site has some rubbish rules about code and won't let me share them so I'll leave you to Google how object and iframe tags work by viewing better sites that actually wants the help from developers.
Have fun guys!

Embed XML in HTML (for Mozilla Nightly)

I've seen that there is another post with a similar name, but it doesn't help me.
I use this:
<embed src="../xml/menu.xml" />
to embed some XML content in a div from an HTML file. It is working (the content is displayed) in Google Chrome and Internet Explorer, but not in Mozilla Nightly.
Do you know how to make it work even for Nightly?
Use <object> instead. Per spec, <embed> will only show content handled via plug-ins and SVG, not random document types like XML.

Show SVG files on Sharepoint 2007

I'm building a WSS site which has to show SVG files stored on WSS.
I'm trying to use <object> tag to show it and it doesn't show, however, if I use <embed> it works ok. Im'using IE8 and IE7
I've been reading and everyone tells IE prefers <Object> over <embed>, but in WSS it doesn't work this way.
To display the file I'm using a web content editor webpart with this code:
<object type="image/svg+xml" data="/samples/sample.svg"
name="owMain" width="400" height="150">
</object>
Any clue??
I've found that it's not actually necessary to embed SVG as an object.
If you use the SVGWeb JavaScript library, you can actually put your SVG into a normal Content Editor Web Part via the Source Editor, and manipulate the SVG elements via JavaScript.
The library can also work with a referenced SVG file as an object, but I haven't tried that option.
The library is hosted on code.google.com
You cannot add object tags to the html content of a page in WSS. The issue is that the object tag can be used in lots of very bad ways, so it is stripped out by the underlying engine.
You have found that the content editor webpart does not suffer from the same limitations.
The first step, if you haven't already, is to confirm that the HTML content in the response is as you expect (e.g. view source). If it isn't then you've found your issue. If it is, the next step might be to use a debugging proxy like Fiddler to confirm that all of the related requests are being made and handled as you expect. If they're not then you've found your issue (e.g. security). If they are then by the process of elimination you can safely conclude that either the markup or the browser is lacking.
Is it me or IE does not support SVG? Well, it kinda does but it is tricky and it's to draw, not to show svg files. ... If you open with FF can you see what you are expecting?

I made an svg draw in IE ... it's not the same, I know, but it's something that you can read and test: stackoverflow.com/questions/536676
I managed to do this on IE7/8 with the following Html:
<embed width="600" height="450" id="objMapView" src="http://XXXXXXXX/file.svgz"
type="image/svg+xml" name="objMapView" border="1"/>
It works Ok bur requires adobe's SVG Plugin

Use of Iframe or Object tag to embed web pages in another

In a web-based system I maintain at work that recently went live, it makes an Object element to embed a second web page within the main web page. (Effectively the main web page contains the menu and header, and the main application pages are in the object)
For example
<object id="contentarea" standby="loading data, please wait..."
title="loading data, please wait..." width="100%" height="53%"
type="text/html" data="MainPage.aspx"></object>
Older versions of this application use an IFRAME to do this though. I have found that by using the object tag the embedded web page behaves differently to when it was previously hosted in an IFRAME. In IE, for example, the tool tips don't seen to work (I will post a separate question about this!), and it looks like the embedded page cannot access the parent page in script, although it can if it was an IFRAME.
I am told the reason for favouring the object tag over the IFRAME is that the IFRAME is being deprecated and so cannot be relied on for future versions of browsers. Is this true though? Is it preferable to use the Object tag over the Iframe to embed web pages? Or is it likely that the IFRAME will be well-supported into the future (long after I am old and grey, and past the useful life of the application I maintain)?
The IFRAME element is part of the upcoming HTML5 standard. Also, HTML5 is developed by the major browser vendors out there (Mozilla, Opera, Safari, IE), that basically makes a guarantee that we will have an IFRAME element in the foreseeable future. Some of them have support for some HTML5 elements already, like AUDIO and VIDEO and some new JavaScript APIs.
It's also true that the OBJECT element is in the draft, but that's because IFRAME and OBJECT will have different purposes. IFRAMES are mainly designed for sandboxing web applications.
So, my advise is to use IFRAME instead of OBJECT.
If you are embedding a HTML page, here is one noticeable difference between iframe and object:
with iframe updating src will change the browser history (adding a new entry)
with object updating data will not change the browser history
Also it seems like drag&drop does not work if the page is embedded in the object tag, but works in the iframe tag. I noticed it personally using react-draggable, and I can see someone had the same issue (https://stackoverflow.com/questions/31807848/replacing-iframe-with-object-tag-drag-and-drop-not-working)
IFRAMEs are not part of the XHTML 1.0 Strict DTD. They are totally valid in in HTML 4 and XHTML 1.0 Transitional, I believe. For these reasons alone, IFRAME will continue to be supported for a long time.
A lot of bookmarklets and analytics code still use IFRAMEs.
Although the W3C specs may indicate that the IFRAME tag is being deprecated, (in XHTML at least anyway), browser developers do not necessarily follow exactly what those specs say (IE6 anyone?)
As use of IFRAMEs is so prevalent at the moment, and the W3C can't seem to decide if they are part of the future or not (HTML 4.01 vs XHTML), I am pretty sure they are the safer implementation to use for almost every browser.

Firefox 3.0.7 is crashing when embedding a PDF using the object tag

I'm attempting to embed a PDF file into a HTML page using the object tag. The following HTML crashes Firefox 3.0.7:
<object id="pdfObject40" type="application/pdf" data="/file.ashx?id=40" width="432" height="600">
<param name="src" value="/file.ashx?id=40" />
</object>
I don't have a problem in Internet Explorer.
Check the MIME-type the ‘file.ashx’ script is returning. If it's something other than application/pdf, or Content-Disposition is getting sent, there might be wrinkles.
Otherwise, it can only be (a) something odd in the document — do other documents load OK? — or (b) your setup.
In any case I would personally avoid ever embedding a PDF in a web page. A PDF plugin is a pretty inconvenient way to view a document, and the Adobe Reader plugin in particular is both historically awfully unreliable in IE, and also an ongoing security disaster. I'm advising all my clients to uninstall it ASAP.
I ended up using that code for IE and failing over to a link with a about:blank in Firefox. If any has a solution, feel free to add. I'll accept it down the road.
Incase anyone else has this problem, I ended up using object element tag with Firefox and embed element tag with everything else.
I think if I'd not been serving the PDF through an .ashx I could have used the embed tag for everything.
