I have a Wordpress site on a LAMP Stack running in AWS. I have Let's Encrypt running to automatically update the TLS Certificate and I re-direct all traffic to the "www." instance for the purposes of SEO.

The site works as expected for EVERY browser EXCEPT Safari. What I mean is that I've tried Chrome, Firefox, Opera, Vivaldi and Internet Explorer. I made not changes to the Server itself and I'm a little perplexed as to what happened. Below is a screenshot from some testing I was doing using BrowserStack. This seems to be happening on all Safari browsers back to iOS7.

Any idea what's going on here? Is this fixable from my end?

Hi,

I am working on C# MVC application.

I have payment integrated in my website. For payments, we call payment url which is loaded in iFrame.
We have no control on the form which opens in iFrame, as it captures credit card details.

Now, once user does the payment by clicking submit button in payment form, which (submit form) is in iFrame.

After successful/unsuccessful transaction we are receiving response in handler page.

After getting response in handler page we are losing session of our web application.

It works well in chrome but does not work in IE, Firefox.

What we should do so that we should not loose our session once the redirect happen.

Also, we see Chrome has same id before and after confirmation done.

But other browser gives us different session id's when returns from payment page.

Please advise the solution.

I have below configuration in my web.config already.
<httpCookies httpOnlyCookies="true" requireSSL="false" />

Hi! I have a user who is having the attached error when trying to open an Excel file directly from a web page when using Firefox. When saving to a specific folder and opening the file from there everything works fine. Anyone have any ideas? It's Excel in Office 365 on Windows 10 Pro.

powershell IE or Firefox open in fullscreen mode.

I am trying to open up a process of IE or Firefox to a specific webpage in full screen mode. when I say full screen I mean the f11 no banners showing. not just windows maximised.

the start-process command is easy to use but I cant figure out how to get it into this full screen mode. the easiest way of doing this in my eyes is using the -K Kiosk option available.

if I run the following cmd from Run it opens as expected: iexplore.exe -K https://www.google.com

how do I achieve the same in powershell?

is it possible to just invoke F11 button and press full screen? as Kiosk mode doesn't allow you to anything but 'close' the session. either solution will work for me.

if a better suggestion is available in Firefox I am open to this as well.

Given the turf wars between Firefox and Google over how they handle and display "secure" web sites, are EV SSL Certificates of any value any more?  

To the general public user that is; I know the CAs think they are of value!

The green bar of IE was nice in its day but that has long gone. A LetsEncrypt certificate site looks pretty much the same as an EV certificate site now to all intents and purposes. I mean, how many users are actually checking this - real world users that is, not us.

And are there any policies enforcable by anything that would prevent accessing a NON-EV certificated site?

We have a bit of jquery to hide/show a div based on the answer provided in a question.  The show portion if the value is over 103000 doesn't work in Edge but does is Firefox and Chrome.  I added the window alert just to see if the stupid thing was even triggering.  It does if I delete the value - it will do the alert and hide the div but if I change something that was 109000 and make it less, it doesn't trigger the hide or the windows alert.  All of this works in Firefox and Chrome.  There is nothing in the troubleshooting that would indicate there is a problem.  

 $('#FI_AGI').change(function() {
		   
		   window.alert($('#FI_AGI').val());
        if ($('#FI_AGI').val()>103000)  {
			 $("#over98").show();
			 $("#agiexplain").show();	
		}
		
		else {
			$("#over98").hide();
			$("#agiexplain").hide();
			
		}
		});

I am running Windows Server 2016 and I'd like to disable Internet Explorer on a server that a handful of "non technical" folks use.

The purpose of this is to attempt to get them to use Firefox instead.

Is it possible to Uninstall or Remove Internet Explorer altogether?

Thanks!

Firefox 70.0.1 in Windows 7.

My Bookmarks (Bookmarks menu > Show all bookmarks) is laid out as:

All Bookmarks
        Bookmarks Toolbar
        Bookmarks Menu
        Other Bookmarks

I save my bookmarks in separate folders I create under the "Bookmarks Menu".

When I used to bookmark a page using the option "Bookmarks" menu > "Bookmark this page" I was shown a dialog where I could choose an existing folder for the new bookmark or could create a new folder in which to save it.  At some point over the last 6 months or longer (I can't remember for certain) the bookmarks are saved automatically in the "Other Bookmarks" folder and all I see up at the Firefox hamburger icon is a green "Saved to Library" notification.

I cannot find any settings in the "Library" window (Show all bookmarks) or in Firefox "Options" to force that original dialog to show so that I can choose where to save each new bookmark.  Any ideas?

Where are my Firefox downloads??????
I downloaded a group of large files using Firefox but the browser didn't ask me where to store them.  the actual names of the files are convoluted and I don't remember their names.
And they're NOT in the downloads folder.
How can I find them.
When I asked to download them, all I got was this dialog box:

Firefox 69 uses way to much RAM on Microsoft RDS Server 2016.

I run a 70 station thin client wyse terminal farm using 4 Microsoft RDS server 2016 servers. This is a test center and I have been using Firefox in a Kiosk mode for years with no problems. Recently I was forced to upgrade from Firefox 62 to 69. Now I have "random" connections using upwards of 5 Gig for thier connection. After 2.5 to 3 gig the students start to complain about lag and any higher RAM than that produces a white screen or a crash.

I have tried the following attempts at resolving this:

1. Because Cache usage was my 1st thought I first tried to change the following Firefox settings:
        a. Browser.session.max total viewers = 1
        b. Browser.cache.memory.max_entry_size = 1280
        c. Browser.sessionhistory.max_entries = 5
        d. After the above did not work I tried - Browser.cache.memory.enable = FALSE

2. To try and squeeze a little more performance out of my RDS Farm servers I did the following (it is a closed environment and this was only to test performance):
        a. Moved the pagefile to a standalone 15K SAS drive dedicated just for the pagefile.
        b. Disabled Windows defender.
        C. Built a brand new stripped down Default Profile
        D. Even changed DEP (windows Data Execution Prevention) to "Windows Services Only".

3. Back to Firefox -
        a. Enabled (checked the check box) "Prevent Accesibility Services"
        b. Under General - …

Good moning !

I use this code to edit the quantity of products from a button. With Chrome it goes very well but with Firefox it sends me an ajax error.
This happens when I change quantities quickly.
If I click on Chrome several times, everything is fine, but on firefox it crashes.
Can you guide me please?

function BTN_EDT(i){
	var $button = $(this);
	var val_R = document.getElementById("ARR_NumId_" + i).value;
	var val_Q = document.getElementById("ARR_Quantite_" + i).value;
    $.ajax({
		type : "POST",
        url: '_produit-update.php',
        cache: false,
		data: {val_R:val_R, val_Q:val_Q},
        error: function(e){console.log('Ajax Error',e);alert('Erreur Ajax');},
        success: function(response){console.log('Ajax Success',response); location.reload(true);}
    });
}

None of the Internet browsers is able to launch

I have Windows 10 on my Laptop. Recently I am experiencing issue with Internet Browsers unable to launch (Chrome , FireFox, Internet Explorer).
Initially I thought downloading AVG anti Virus and Malwarebytes were the cause of this issue, but even after I have gone and removed them, the issue is still not resolved.
I tried to restore the system to previous versions, but I do not see a very old date.  the oldest version is 9/20/2019, I went ahead and restored the system to that date version, but it is still has not resolved the issue.

I do not have Windows 10 DVD, I remember it was a free upgrade from Windows 8.1 to 10.
I am not sure if there is a way to repair the OS.  I am writing this question from another computer as my laptop cannot launch any internet Browser.

Any Assistance will be very much appreciated.

Thank you.

We have a Sonicwall firewall and there are NAT working well.

Recently, we need to setup a new NAT (TCP: 19832) from external to our internal server. My setup is as below:

1. Copy other NAT rule, and allow the port, but no luck
2. telnet the port by internal network, it works
3. To setup NAT by tp-link, it works by telnet in external network
4. Change to another tcp port, not luck

I have double check the NAT and firewall rule, there is no hints on it.

Anyone has hints on it? Is there magic difference between TP-Link and Sonicwall NAT (port forwarding)?

I check on firewall, there is activity on hitting the NAT rule, but no traffic...

Hi, I have just noticed that when I try to make Firefox smaller by clicking on the center (square) type icon on the upper right, it just kind of re positions the full screen but does not make it smaller.  I tried it on Chrome and it worked just fine as well as Excel and Word.  I want to have an excel document take up the left half of the screen while I look stuff up in Firefox on the right side of the screen.  I've never run into this before and would appreciate your help.
Thanks

I have an old Presario V6000 running Win XP.  For some time now I haven't been able to play "certain" videos such as video clips from Fox News and some videos from youTube.  Most of the time I get an Error 4 message. I just upgraded Firefox but their message said it no longer supported my system.  So, bottom line is; I can play most you tube videos but not others.  Shoud I try to fix the error 4 message or junk this laptop?
Thanks

We have an alert that pops up when users are accessing our site through Internet Explorer to let them know they are using an incompatible browser. It should only pop up when the user is using Internet Explorer.

We have a client who uses ELO devices to access our website. They are getting this alert. Our website tracks what type of browser the user logged in with. It is returning Firefox version 47, but they are still getting the alert.

This is the function we use to check the browser the customer is using. The function is being used in a control on the master page.

  Public Shared Function IsInternetExplorer() As Boolean
        Dim isIE As Boolean = False
        With HttpContext.Current.Request.Browser
            If UCase(.Browser) = "INTERNETEXPLORER" Or UCase(.Browser) = "IE" Then
                isIE = True
            End If
        End With
        Return isIE
    End Function

Open in new window


We've tested the website on various browsers, and the alert only pops up on IE, but for some reason our client who uses an ELO device shows the alert. It's not even popping up right away like it's supposed to. It pops up after the user has been logged in for a while and is taking our training. Is there something with ELO devices that alters what browser they are using? We have no way of testing this so we are unsure how to proceed. Is there a way we can correctly detect what browser the ELO is returning?

This problem occurs in Firefox 52 and later.

When this SSI HTML page is served up by the server, the Javascript appears to not execute in Firefox, though it works correctly in my HTML editor and in IE.

<HTML>
<HEAD>
<TITLE>Home Page</title>
</HEAD>

<BODY>

<!-- Included header file to be inserted below BODY -->

<DIV ID="header">

<TABLE BORDER="0" WIDTH="100%" CELLSPACING="0" CELLPADDING="0"><TR>
<TD>
<script type="text/javascript">
<!--
 var image_number = 0;
 var image_count = 10;
 function randomimage() {
 	image_number = 1 + Math.floor(Math.random() * image_count)
 	return(image_number)
 }
  document.write("<img src='/headerimages/header" + randomimage() + ".png'>");
//-->
</script></TD>
<TD><IMG SRC="/headerimages/rightheader.png"></TD>
</TR></TABLE>

<P>&nbsp;</P>

</DIV>

<!-- End of included header file.  Content follows. -->

<!-- Content section begins here, below the header -->

<DIV ID="body">
<P>&nbsp;</P>
<P>&nbsp;</P>
</DIV>

<!-- End of the content section -->

</BODY>
</HTML>

I admit that this Javascript was cookbooked.  I never use it myself, never had any reason to until now.

Side note:  I just need to know what the problem is with the Javascript.  I know that this is not HTML5 compliant and there are probably other issues too.  This is part of a patch being laid atop an old site and it will have to do.

Since a few days, the JS debugger in Firefox (68.0.1) doesn't open JS files correctly. Instead, some HTML is displayed. The JS files do not have a file extension at all, yet the Content-Type header correctly contains application/x-javascript. Other files with js extension do show up with a JS icon in front of them.

Is this a recent change? What can I do to make those files show up correctly in the debugger? Or is it a new "feature"?

The application I use is built in XPages, so there might also be some setting there that used to create files with the .js extension, but I'm not sure of that.

I can confirm that xcsDocument definitely contains JS, and that Firefox has no problems in using it. No JS errors displayed, no HTML errors, nothing significant on the Console tab.

Thanks for your help!

Firefox dev tools no longer displays JS files without .js extension
