Hi everybody,

I have only one Exchange 2016 CU9 server with all roles. It's working fine.

I have one problem with OWA from external. The external IP of the Exchange server is a NAT in internal server IP.

When I'm in external, if I go on the OWA, I have the form that ask me for the username and password.
I enter the credentials and I have this error. Same problem with Firefox and Chrome.  
If I click on "Refresh the page", owa is displayed and working fine.

I did a lot of tests.
If I did the same thing but i'm waiting 2-3 second before enter my credentials, owa is weel and immediately displayed. It's like there's a timeout.

I don't have problem with Outlook and autodiscover, only this "timeout" with owa.

Do you have an idea ?
Many thanks for your help.
Best regards

After readjusting screen resolution in Firefox (layout.css.devPixelsPerPx) to 1.0, the EE question description popups are almost unreadably small -- see image below.

Small text size in description popup
I know that the text in question is not controlled by any of the userChrome.css options in the list below - these are already defined.

menubar > menu
.bookmark-item > .toolbarbutton-text
searchbar .searchbar-textbox

What userChrome text option controls the size of that text?
I have a relatively simple page that renders differently depending on whether the page is located on the web server or on the browsing system as a local file.  The HTML file being rendered is identical in both cases.  The problem appears to occur only in Firefox.  IE renders correctly for both situations.

While it is true that embedding styles in a link is not considered "best practice", the only links where this particular styling are desired are at the bottom of the page.

The server is Apache, and I have checked that the HTML being received (appears to be) the same as the HTML file on the host.

What is the issue causing this rendering difference?

Win7Pro/64. Firefox latest version. Friend was copying some data from my machine and using Firefox. Next day, the Firefox screen was in the middle of my dual monitor setup, 1/3 on one side of bezels, rest on the other. I've read about this problem on single monitors where only a third or half of the FF screen comes up. I tired all the suggestions - deleting the two files always mentioned, looking for something in the FF profile that might affect this. I can grab and move the screen, but the position will not stick after FF shutdown and restart - only half the window shows, or in my case, window split between two monitors. Again, I've tried all the Mozilla forum suggestions save a reset/refresh. This does not happen with any other program.
I created a 301 redirect on .htaccess file on linux shared server website

I did it incorrectly and have changed redirect to another website

But firefox browser windows 10 (my machine only: I did not try on other computers) still has first redirect.
I dont want to close browser or restart my windows 10 computer
I am running my desktop on Linux Mint 19.0. Recently when I use any browser (Firefox, Chrome), uncountable tabs appear which I didn't request. I re-installed Firefox and Chrome, I have rebooted the machine but to no avail. Does anybody know what the problem is and how to fix this?
I need to find out if my desktop can be fixed for free, using my own skill level and get my pop ups and get the virus out of my computer.  I do not have  much savy on computers and i really like using but the last two years or longer, it's been going on. Linus 17 has kept every type of self help from being done. That's why i am here, because i am at my wits end. Can you help me at all, for free, or is it out of the question?  Desperate in the Hoosier state, and i do not mean maybe.
I have linus 17, and I use Firefox, I can not get rid of pop ups and I suspect I have multi virus in my computer. The Linus will not allow any kind of self repair of any kind, including online. I have limited income because of Social Security. I have had this for well over two years what can I do in such negative circumstances? Please help, in DIRE NEED IN THE HOOSIER STATE.
Firefox has been a dog on my Windows 10 computer for the past six months.  I closed it out and Chrome just seems to keep on pluggin.  I've done some uninstalls/reinstalls of the application a couple of times as I tend to try bounce  between the two.  I was wondering if other people experience high memory usage and general slow response for page loads or is it just me.  Any steps to correct this beyond, cache, cookies, and some other basic steps?     I removed all plugins and there is no Flash on my computer beyond the built in Chrome one.  Some sage advice would be appreciated.
Bandwidth much more narrow in Firefox than other browsers..?
When making a bandwidth check with or from Edge and Chrome I get 110-125 Mbps in download, while only 15-40 Mbps in Firefox.
PC with Win10 (up to date with Windows Update) and Firefox (also up to date).

No plugins/addons in Firefox to limit bandwidth. No difference when starting Firefox in safe mode either...

Any ideas?

Hi, The checkbox is not getting focus while pressing the Tab keys for the IE and Firefox. But if I press enter or using mouse, the checkbox is working fine. For the Chrome, Its working fine.

I'm really don't know there is having problem with either javascript or CSS.

While Inspect the checkbox Id, its having delete-for-reals

<input name="delete-for-reals" class="ember-view ember-text-field text-field component" id="ember7661" type="checkbox">

Open in new window

So I have find the id names on my projects in

CSS file as below:

.delete-for-reals img,
.delete-for-reals input {
  vertical-align: middle;
.delete-for-reals .rsuite-message {
  vertical-align: -2px;

Open in new window

Hbr file:

{{#if view.isReferenced}}
		<p class="delete-for-reals">
			<label for="delete-for-reals">
				{{icon model=view.trashCan size=20}}
				{{view Ember.Checkbox checked=view.deleteMode id="delete-for-reals"}}
				{{#if view.deleteMode}}
					{{message "dialog/destroy/labels/uncheck-to-remove"}}
					{{message "dialog/destroy/labels/check-to-delete"}}

Open in new window

And Dialog.less file;

	.rsuite-message {
		vertical-align: -2px;

Open in new window

So totally the id available in .css, .hbr and .less files.

Please help me on this. Thanks in advance.
When a stored response is used to satisfy a request without validation, my browser is not showing me the HTTP reponse header field: "Age"?

Just take a simple test.html file, which is chacheable by default. Now visit the page 2 times, so the second time the file is shown directly from cache without validation.

Firefox shows me response headers like this:

Date: Mon, 12 Mar 2018 16:05:18 GMT
Server: Apache/2.4.17 (Unix) OpenSSL/1.0.1e-fips PHP/5.6.16
Last-Modified: Mon, 12 Mar 2018 12:24:12 GMT
Accept-Ranges: bytes
Content-Length: 143
Content-Type: text/html

Open in new window

But why Firefox does not show me the "Age" header field?


When a stored response is used to satisfy a request without validation, a cache MUST generate an Age header field

And see:

However, lack of an Age header field does not imply the origin was contacted, since the response might have been received from an HTTP/1.0 cache that does not implement Age.

A browser's cache is not HTTP/1.0, so the response headers must contain an Age header field. Firefox is not showing me "Age"?

Are browsers only showing the response and request headers of the server? But if that's the case then they had to show no response headers at all, because there was no response from server in case of "200 OK (cached)"?

So I don't understand this? What's the logic behind this?

P.S. The example was about Firefox, but for example Chrome is doing the same.
I just did a test in Firefox. I have an PHP file (without sessions). The reponse headers do not contain a validator or any other caching related headers, except:

Cache-Control: no-cache

Open in new window

When pressing the back button in Firefox followed by the forward button, the file is coming from cache when coming back on that page.

With "Cache-Control: no-cache" (and no validators), usually you would expect a request to the origin server, resulting in a "200 OK" response (NOT from cache).

I know that there is some different caching behavior with the back / forward button. See:

6.  History Lists

User agents often have history mechanisms, such as "Back" buttons and
history lists, that can be used to redisplay a representation
retrieved earlier in a session.

The freshness model (Section 4.2) does not necessarily apply to
history mechanisms.  That is, a history mechanism can display a
previous representation even if it has expired.

This does not prohibit the history mechanism from telling the user
that a view might be stale or from honoring cache directives (e.g.,
Cache-Control: no-store).

Here they are saying that the freshness model does not necessarily apply to history mechanisms. So when using max-age=0 or something like that (Expires), I can understand that the back and forward button can serve stale responses.

But no-cache is not part of the freshness model or is it? …
Firefox on more and more windows 10 Pro machines after Firefox updates give the following error and block ALL sites.  As per Mozzila - it isn't them.

sec_error_bad_signature only via proxy for https website.  I keep seeing this more and more at different sites.  Antivirus totally disabled even.  Chrome/Edge/IE work fine.  Also seeing what appears to be a huge memory leak on Firefox, a browser with no third party plugins and 5 tabs shouldn't use over 2 GB of RAM after a few hours.  Any one have a fix for all sites being blocked?

Hi there:

I have set up a printable page using css which renders well in chrome. However, in Firefox, the header is printing on every page. I tried to switch the tag to div with a class "header" and I got the same issue.  Is there any way to keep the header from printing on page 2 and beyond in firefox?

here is my code:

<!DOCTYPE html>

<meta http-equiv="content-type" content="text/html"; charset=utf-8" />
<meta name="keywords" content="los angeles, hollywood" />
<meta name="description" content="talent and literary management in Hollywood" /> 

<title>XXXXXXXXXXXXXX </title>

<link rel="stylesheet" type="text/css" href="newreelresumecss.css" />
<link rel="stylesheet" type="text/css" href="newreelresumeprint.css" media="print" />

<link rel="shortcut icon" type="image/x-icon" href="archetypeico.ico" />

<link href='' rel='stylesheet' type='text/css'>


<a href=""><img src="largelogo1.svg" width="325" height="69"/></a>

Hello Everyone:

I am sure some of you have run into this.

I have a locked down environment where users are not allowed to install software onto their PC.  Mozilla Firefox provides users the ability to install Firefox into their C:\Users\%Username% directory.

I am sending an SCCM package to uninstall Firefox, however I am deploying the uninstall package to be run only when the user is logged on so it will remove the entire program with the user's rights and to also remove the program from their C:\Users\%username% profile and HKCU registry keys.

When I try to run the Firefox uninstall program using the recommended "helper.exe -ms" command line, I am immediately prompted with UAC inquiring: "Do you want to allow this app to make changes to your device?" and the following command line is shown when I click on to "show details"

C:\users\%username%OneDrive\Firefox\uninstall\helper.exe /UAC:2C090A /NCRC -ms

If I click on the No button in the UAC window, Firefox will get installed.

The million dollar question:  Is there a command line parameter I can run with helper.exe with "user rights "so it will run silently without prompting with UAC?  It seems it is uninstalling Firefox with user right because I am clicking on "No" at the UAC prompt, but I would prefer to avoid to have the UAC screen from appearing.  For the Chrome "user" uninstall, Chrome provides "--user-level" to used on their uninstall command line and UAC is not prompted at all.

Any thoughts on how…
I run 3 different browsers (Edge, Firefox and Chrome)

For some websites Chrome and Firefox display content garbled, and I have uninstalled, reinstalled them both, checked fonts, cleared caches, deleted browsing history, deleted all content and the issue just doesnt go away. It only happens for some websites (Facebook being one)

As an additional symptom, when I View source I get the same results - which would suggest its font related...

I dont want to rebuild (its my machine) but I am out of answers.... so throw something at me.
What the?
Hi Experts!

I had some issue with the web browser especially in IE and Firefox. for some reason when I refresh the page I get an additional string like this: http://wysiwyg/0/ instead of

Google chrome is the only browser that I don't get this issue. Thanks
Hello everyone! I'm new here and I hope that you can help me.  I have problems with search redirects in my browser. Some sort of virus redirects all my search request’s to misleading search[dot]queryrouter[dot]com website. I use Firefox 51.0.1 along with Google Chrome and story is the same in both browsers. I have tried several methods:
-AdwCleaner -
-JwRT -
-Manual removal guide -
-Create new Windows account.
I performed full system scan’s and performed manual removal in Normal Windows mode and in Safe Mode with Networking – but this virus appears after first reboot again and again.
And only new account helped me to get rid of redirects and surf without any problems. But it is not a best way out. So I want to ask you how can I remove this virus from my main Window account?
Thank you for your assistance!
