Sec_error_unknown_issuer for a certificate trusted by every other browser

Dear Forum mebers,
I completely gave up this, so I hope somebody may have seen this issue and could resolve it :) We have an intranet corporate site, based on Windows Server 2012 R2 IIS server. I built up a single, WS2012R2 Standalone Root Certification Authority, and this CA only issued just one certificate -> for this site. After this, I imported the CA certificate to the trusted root certification authorities node via Group Policy.
Now, every single web browser can open the page without any problems (since the CA is trusted), only FireFox not. The issue happening is sec_error_unknown_issuer. What could I do with this? I tried to google a lot, but there is always speaking about intermediate certificates and certificate chain. But this time, there is absolutely no intermediate CA, since I have only a Root CA!
Are there any suggestions which I could try?
Thank you a lot for your help!
Best Regards,
Christian

Is that root certificate also imported in Firefox because Firefox uses its own certificate storage and stores extra certificates in the cert8.db file in the Firefox profile folder?

Animated gif files not working in FF5 ok in every other browser

Hi .
I am having problems getting animated gifs to play in firefox 5 i am using a photo gallery script to show these files it works in every other browser i have access to (most of them on Linux and windows Xp and win7 ) if i use FF5 as a file manager and navigate to the files they run but not from a web page this is only with firefox 4 and 5 not got previous to 4 to test .

Right . this looks like it may be a problem with the way FF5 is handling various methods of viewing images i use the following code .
<pre><nowiki><a class="thumbnail" href="#thumb"><img src="photos/IMG_7039 EOS-1D Mark III copy.jpg" width="100px" height="75px" border="0"><span><img src="photos/Animations/IMG_7039 EOS-1D Mark III copy.gif"></span></a></nowiki></pre>
along with css .
<pre><nowiki>(
.gallerycontainer{
position: relative;
/*Add a height attribute and set to largest image's height to prevent overlaying*/
.thumbnail img{
border: 1px solid blue;
margin: 0 5px 5px 0;
.thumbnail:hover{
background-color: transparent;
.thumbnail:hover img{
border: 1px solid blue;
.thumbnail span{ /*CSS for enlarged image*/
position: fixed;
background-color: lightyellow;
padding: 5px;
left: -600px;
border: 1px dashed gray;
visibility: hidden;
color: black;
text-decoration: none;
.thumbnail span img{ /*CSS for enlarged image displays the large image*/
border-width: 4;
padding: 12px;
.thumbnail:hover span{ /*CSS for enlarged image*/
visibility: visible;
top: 0;
left: 230px; /*position where enlarged image should offset horizontally */
z-index: 50;
)</nowiki></pre>
to create the gallery now if i navigate directly to the dir with the gif images in they work ok but if i use the gallery method they fail .
Tried safe mode no addons no change ..

Install the latest update of Reader or Acrobat (done, no effect)
Adobe releases free security updates quarterly. It is important to update your version of Reader or Acrobat to the latest release. The updates often include fixes to common problems. Download the latest free update:
Note: Microsoft Windows 7 requires Adobe Reader 9.2 or later.
1.      Open Reader or Acrobat.
2.      Choose Help > Check for Updates. If a new update is available, it installs automatically.
3.      Once installed, restart your computer.
To the top<http://helpx.adobe.com/acrobat/kb/cant-view-pdf-web.html>
Refresh or reload the page (done, no effect)
Often, just refreshing the page allows the PDF to load fully.
Hold down the Shift key and press the    Refresh or    Reload button in the browser.
Try to view a different PDF (done, no effect)
Try viewing a different PDF. For example, see if this sample form<http://help.adobe.com/en_US/Acrobat/9.0/Samples/flatform.pdf> displays in your browser.(DOES NOT OPEN) If Acrobat or Reader can open the sample form, then the other PDF could be damaged or the web server could be having problems. If possible, contact the individual or company who manages the website.
1.      Try to view a PDF on your hard drive . (ALL PDFS OPEN ON HARD DRIVE)
To the top<http://helpx.adobe.com/acrobat/kb/cant-view-pdf-web.html>
Problem with the browser or its settings?
Use a different web browser (Pdf'S open in alternate browsers)
Certain conditions on your computer, such as security settings or browser cookies, can prevent you from viewing a PDF. Often, the fastest solution is to try to open the page using a different browser. Try any of the following browsers that you have not already tried:
Mozilla Firefox<http://www.mozilla.com/firefox/>
Microsoft Internet Explorer<http://www.microsoft.com/windows/internet-explorer/default.aspx>
Apple Safari<http://www.apple.com/safari/download>
For a list of compatible browsers for Reader and Acrobat X, see this list of Compatible web browsers<http://helpx.adobe.com/acrobat/kb/compatible-web-browsers-pdfmaker-applications.html>.
Switch to Compatibility View (Internet Explorer) (done, no effect)
Some websites display better in the Compatibility View of Internet Explorer. The Compatibility View displays a page as if it was an earlier version of the browser. For instructions on how to switch to this view, see one of these documents on the Microsoft website:
Internet Explorer 9: How to use Compatibility View in Internet Explorer 9<http://windows.microsoft.com/en-us/windows7/How-to-use-Compatibility-View-in-Internet-Expl orer-9>
Internet Explorer 8: Why are some web pages blank or incorrectly displayed in Internet Explorer<http://windows.microsoft.com/en-US/windows7/webpages-look-incorrect-in-Internet-Explorer>.
Restart your computer and try opening the PDF again (done, no effect)
Restart your computer, then open the web page again. Restarting clears the computer memory and memory cache. It is surprising how often simply restarting your computer resolves a display issue.
Delete temporary Internet files (Internet Explorer, Firefox, and Chrome) (done, no effect)
Clear the browser cache (sometimes called 'temporary Internet files') to ensure that you are viewing a fresh version of the page. When you open a web page, the browser saves a temporary copy so that it opens more quickly next time. You want to force the browser to load the entire page directly from the server, rather than displaying a stored copy.
Reset the Display PDF In Browser preference (done, no effect)
1.      In Reader or Acrobat, right-click the document window, and select Page Display Preferences.
2.      From the list at left, select Internet.
3.      Deselect Display PDF In Browser, and then click OK.
4.      Choose Edit > Preferences > Internet, select Display PDF In Browser, and then click OK.
5.      Try to open the PDF again from the website.
View PDF in 32-bit version of Internet Explorer or Safari (done, no effect)
Acrobat and Reader are 32-bit applications on Windows. If you try to open a PDF in a 64-bit version of Internet Explorer, the PDF opens in stand-alone Acrobat or Reader, not in Internet Explorer.
Remove DreamFactory (Firefox only) (done, no effect)
If you receive the error "Cannot use Adobe Reader to view PDFs in your web browser," do the following:
1.      Choose Start > Run, type appwiz.cpl in the Open text box, and then click OK to open the Add Or Remove Programs dialog box.
2.      Select Change Or Remove Programs in the Add Or Remove Programs dialog box, select DreamFactory Runtime for Netscape, Mozilla and Firefox, and click Change/Remove.
3.      Click OK in the Remove Programs From Your Computer dialog box.

Problem with Reader or Acrobat?
Remove unmatched or multiple versions of Reader or Acrobat (already did this including running a cleaner from the Adobe site) (done, no effect)
Repair Reader or Acrobat (done, no effect)
Reader or Acrobat could be damaged. Repairing the installation is a quick troubleshooting safeguard.
Repair from within Reader or Acrobat (done, no effect)
(Reader) Choose Help > Repair Adobe Reader Installation.
(Acrobat) Choose Help > Repair Acrobat Installation.
Repair using Control Panel (Windows) (done, no effect)
You can also repair your Acrobat or Reader installation using the Windows Control Panel.
Enable the Adobe PDF browser add-on (Internet Explorer) (done, no effect)
Make sure that the Adobe PDF browser add-on, AdobePDF.dll, is enabled.
Run Acrobat or Reader in a new local administrator account (done, no effect)
Optimize large PDF files (not the problem)
If the PDF file is 4 MB or larger, ask the provider to optimize the PDF file. For information about optimizing PDF files, see

When i try to connect to facebook with firefox, facebook wants me to send in card informaion and says that there have been unusually behavior in my account even thought it hasnt, it works in every other browser?

When i try to connect to Facebook with Firefox, Facebook tells me to Verificate my account with my cardnumber and also my adress, it tells me that We detected some unusually behavior in your account, for your security in order to can access your account please send us all requried informations, the credit card number must be yours or a member of your family. We won't save the credit card in our datebase and won't make any charges. We ask only for verification purpose.
Why is this? Facebook works with every other browser and on other computers and i dont have trojan.

I had the same prob. but recently i just formated my laptop and after that it starts working finely in firefox i think it was a kind of virus that discont. after formating the laptop. only windows drive....

Slices NOT working in Internet Explorer -- but work every other browser!

I've spent all day trying to figure this out and hope someone experienced here can help me out.
I've created a left menu for my website using slices (in photoshop cs2). Everything seems to work fine - I upload the date folder and html file to my server, etc. However, when I load that page in IE (any version), it loads really slowly and then shows "x" boxes for the last several slice images.
It works perfectly in every other browser (FF, Opera, Safari, etc). What could the cause possibly be? I've just reformatted my computer so I doubt it's internal. Strangely, it works fine on some computers with IE, but not others.
Any help most appreciated!
thanks

My wild guess will be a browser cache issue. Hold down the Shift key while clicking the Refresh button and see if that helps. If it doesn't we'll definitely need a link.

Firefox won't start up, when clicked, whereas every other browser works.

Firefox won't start up, when clicked, whereas every other browser works.

See:
*http://kb.mozillazine.org/Browser_will_not_start_up
Can you start Firefox in Safe mode?
*https://support.mozilla.org/kb/Safe+Mode
*https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes
You can use one of these to start Firefox in <u>Safe mode</u>:
*On Windows, hold down the Shift key while starting Firefox with a double-click on the Firefox desktop shortcut
*On Mac, hold down the Options key while starting Firefox
*Help > Restart with Add-ons Disabled
Another possible cause is security software (firewall,anti-virus) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

Why does safari not show my websites SVG images and every other browser it is fine ?

I am a web developer and the way apple has developed there safari is driving everyone mad
SVG images will work on every other web browser but wont show up in safari
it is a html website and need to sort this issue out asap have anyone else had the same issue with safari

I wanted to make it clear that I am not talking about the publically accessible Amazon Store but the Amazon Web Store which is used for those who have an online shop or set up e-commerce.
The fact that Amazon is a large company does not protect it from making a crappy site. If its e-commerce pages don't work in Safari, that's laziness on the part of their web developers, pure and simple. There's no reason for a modern web site to fail to work in any standards-compliant web browser. This is something you'll need to address with Amazon.

Still cant scroll vertical in FF4 ...this works in every other browser???

I cant do a vertical scroll with my touch pad in FF4 browser ... my drivers are up to date and I don't have this issue with any other browser on my system except FF4 ... windows 7, 500gb hdd, 4gbram...very frustrating...

FFresFF crashing and restore session has been crashing without warning or notice for the past two weeks every other day, losing my restore session open windows

several times in the past 2 weeks, i come back to my computer to find FF has closed. there are no alerts or notices of a crash. when i use restore session, only 3 windows are listed as "recently closed", when I have 20 or so open. i believe there have been 2 updates in that period. i have to manually go through 'all history" to find my missing windows!

every time I have a problem with FF recently, someone suggests this. I try it and learn nothing.

(Firefox is so extremely slow, it's unbelievable (google needs about 1 minute to load). Every other browser works perfectly fine. How is that possible

I love Firefox and I still want to use it but my love doesn't go as far as waiting one minute for every page to load.
I deactivated every Plug in. I tried with the other versions Firefox offers (moon something).
I uninstalled several times and installed it again.
Please Help Me!!!!!!

uninstall the proxytube addon and set firefox to "use no proxy" under options > advanced > network > connection - settings... in order to get back to the normal browsing speed

Problem with ie6 displaying different to every other browser

I have just created my website and after testing with all browsers except (stupidly) ie6 it all works fine but for some reason in ie6 it displays incorrectly on this page http://www.flitecarz.co.uk/WD-Postcodes-Covered.html the part with the problem is on the right hand side where there is a quick navigation to different postcode areas. If you view it in any browser except ie6 you will see how its supposed to work.
If anyone can give me any help with this I will be forever in your debt as I have been racking my brains about this all day and I cant seem to find a soloution.
Any help with be greatly received.

Hello Nessa,
here is another argument why you don't need to mourn about a possible bad presentation in this old IE6 Browser. This browser - you can say - is no longer in use. The spread is, the statistics shows it, very very low. The attached analysis from
http://gs.statcounter.com/#browser_version-ww-monthly-201201-201202-bar
shows this clearly.
And as we already said, your website looks very well in contemporary browsers.
Don't worry, ...

My website doesnt center in firefox, but works in every other browser

Just like the title states.
For some reason it doesn't center, and you can't use the mouse wheel to scroll through the website.
Any help is appreciated, thanks.

Looks basically the same in Firefox, IE8, and Opera 21 - that page loads set to the left of the page. As far as scrolling horizontally with a mouse wheel, I haven't had a version of Firefox ''[since day one of my use of Firefox in 2002 with Phoenix 0.3]'' that would do horizontal scroll with a mouse wheel, even when I was using a dual-wheel mouse. I have read in Firefox support fora that other users were able to do horizontal scrolling, but I have seen that first hand.
That along with the vertical height of the page being too high, with no vertical scroll bar to read the bottom few lines on my monitor - 1280 x 768 - yep somewhat low resolution in this day and age for a desktop PC, but what about users with small screens, like a netbook with only 600 px vertical height?
That page is so wide that it would take the width of 10 monitors to display that page. What's the point in creating a page like that?

I cannot upload pictures to Facebook in 'Messages' using Firefox, but every other browser will.

I used to be able to, and have only been able to one time since. It started this in about vers. 6 I believe, and has been going on for a few weeks. I've deleted and redownloaded Firefox twice, with the error still occurring.
Thanks,
Mark
