Firefox Support Forum

After Firefox updated, I can no longer access www.apple.com. This is the error I get now:

Blocked by X-Frame-Options Policy

An error occurred during a connection to idmsa.apple.com.

Firefox prevented this page from loading in this context because the page has an X-Frame-Options policy that disallows it.

Can anyone tell me how to fix this issue as soon as possible. Thank You.

The issue seems to be with DRM. Although DRM videos play on other sites like on Amazon Prime Video. I've done everything I could find on the internet as to fix this issue like I've checked and unchcecked play DRM content in the settings and cleared cookies and cache and everything but nothing seems to be fixing the issue. Also, everytime I load Netflix I get a little yellow dialogue box saying installing components please try again. This happens everytime I load Netflix. Now when I click on any video it asks me to install SilverLight, I've installed it already but still it asks me to install it to play the video.

I'm using Firefox 67.0 under MX Linux. My monitor is 25" with a resolution of 1920x1200. With this resolution, the text and icons in Firefox Menu and Toolbars are tiny and almost impossible to read. The Thunderbird add-on Theme and Font Size Changer works reasonably well for Thunderbird, so is there a corresponding add-on for Firefox?

I know that Firefox is largely developed by people who are volunteers, but it seems that a tool, as part of the basic Firefox program, should be available to make these changes without installing add-ons or modifying the code manually. Almost everyone needs to be able to tweak these things at one time or another.

I want to run with safety a Java certified web based applet. It's a Java game which it's certified. I have the latest Java version. I downloaded 52.9 ESR Firefox which there is a problem with it https://support.mozilla.org/en-US/questions/1235246#answer-1158505 , and I have noscript and https everywhere except from antivirus. Is it possible while playing, another script which does not belong to game to run?

I no longer see ads when I read email, look at a magazine or newspaper article etc. Some sites don't like this and won't let me view what's on them because I am blocking ads. I have looked at Options>Privacy and Security>Tracking Protection and it is not turned on. It is only on when I use a privacy window which I am not using. I have no idea where to look to be able to modify this. I have cookies enabled.

I will admit I have far fewer crashes now that the ads do not display in email and I am happy about that but when a site I belong to won't let me read there because ads are blocked that becomes a problem. Do I have any control over this feature? I only use Firefox on my pc that runs Win 7 Professional and I use version 60.3 esr 32 bit because I still run into situations where Java is required and it was explained in an earlier question that I should use Firefox esr because of this.

Until today the options for stopping videos auto playing worked OK, suddenly they don't work at all. I had changed all the settings in about:config - please see screen shot attached - a couple of weeks ago when they suddenly started auto playing and that solved the issue, but now I am back to square one. Even when I have ensured that the autoplay option is changed in the preferences section they are still auto-playing. Any suggestions please as this is driving me crazy!

Thanks in advance for your help. It is much appreciated.

Firefox detected a potential security threat and did not continue to www.google.com because this website requires a secure connection.

What can you do about it?

www.google.com has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

The issue is most likely with the website, and there is nothing you can do to resolve it.

If you are on a corporate network or using anti-virus software, you can reach out to the support teams for assistance. You can also notify the website’s administrator about the problem.

When I go to att.net to check email, firefox takes me to several other sites, one of which sends me a scare screen, hoping I will click on it. I suppose you would call this malware. Is there a setting in FireFox to prevent it from going to sites I did not ask it to?

I will try to add a screen capture of the offending screen.

On saturday our global sertificate expired and we renewed it a bit late. Now Firefox users cant visit our site, seeing this error message.

   Secure Connection Failed. 
   Please contact the server administrator or email correspondent and give them the following information: Your certificate contains the same serial number as another certificate issued by the certificate authority. Please get a new certificate containing a unique serial number.
   
   Error code: SEC_ERROR_REUSED_ISSUER_AND_SERIAL 
   
   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. 
   Please contact the website owners to inform them of this problem.

Unfortunately the only way to fix it we found is deleting the whole profile, deleting the sertificates themselves does not work for us. It is very difficult for our users to do it. Can you please help us with this problem?

Tried to access my online bank account from your website but got a message that it's not a secure site. I called my bank who told me that it's because of one of your updates. How can I fix this issue? I can access my account from other sites, just not yours.

Flash Player 32.0.0.101 Firefox v64 (64-bit) Windows 10

With this configuration Flash content does not work.

On Windows 7 Enterprise, the same version of Flash Player and Firefox

It looks like it is trying to load under Windows 10 but ultimately what is displayed is a blank screen.

Is anyone else running Windows 10 with Firefox and Flash Player and getting it to work. I cannot post the URL because the application is a inhouse application and requires logging in.

The problem exists since yesterday. Today I repared Mozilla. After this the problem first does not exist anymore, but less hours later the problem is here again. My Firefox is not too old. I use Firefox Quantum.

Firefox won't open any links when I search something. I have to go to Chrome or Safari. Just deleted and reinstalled Firefox but am still having the same problem.

I'm receiving the error that the firefox 62 version that I have does not "recognize any of the video formats available" on youtube and I have also been having trouble with being unable to open other webm formats. I have as the other solutions asked refreshed firefox to it's factory state but that has still not solved the problem. I have checked the plugins page and it does show that the openh.264 plugin is there. Not sure why this could be happening. Ubuntu Linux 18.04

Hello!

I use FF 65.0 / 64 bit Windows 10 Pro N / 1809 / Built 17763.292 Nvidia driver 418.81

In this version of windows, but also in the last one, FF causes Windows blue screens (KMODE_EXCEPTION_NOT_HANDLED). It happens after some time working with the browser, especially when many tabs are open and videos are played. But not always - I cannot reproduce it. I just know it always happens when I browse in FF.

I have uploaded the corresponding MiniDump file on my cloud storage: https://box.medunigraz.at/s/ccJj8qbC9mESAjL

I also include my DxDiag file, so you can see what I have installed.

Thanks for any help, best wishes, Herwig

When I want to search for something on a website, I hit CTRL-F which activates full-screen mode. I would like to know this shortcut can be reprogrammed to search for something within a page instead of activating full-screen. I tried searching this community and on-line for this information but could not find it. Thank you for your time. I use Mozilla FireFox 67.0.4.

C:\Users\Freedome\AppData\Roaming

in that pat there is a folder called AMozilla  and inside a folder called Afirefox and is full of files

us this imgur link to see screenshots of the content of the folder https://imgur.com/a/V62kKeE

theres also a Mozilla folder in

C:\Users\Freedome\AppData\Roaming

which one is real ?  is it a malware of some sort ?

Whenever I go on a lot of sites a popup will ask if I will allow notifications from this site, and I accidentally clicked ok on a spam site. How do I get notifications from this site to stop?

I want to build a progressive web app. This app requires the user's GPS coordinates. In order to test this functionality cross-browser, I use w3schooll geolocation implementation. Link: https://www.w3schools.com/html/tryit.asp?filename=tryhtml5_geolocation

Compared to Chrome, Firefox sometimes returns the wrong coordinates. For example yesterday (13/03/2020) the coordinates were wrong all day. Today (14/03/2020) the coordinates are right. The coordinates are crucial for the success of the app. I use Firefox 74.0

Hello,

Does Firefox support Office 365 online? I opened a Word document on Dropbox website and I got a message that office is not supported in this web browser. My computer has Windows 10 OS and I used Mozilla Firefox Developer as well as Mozilla Firefox. A colleague of mine has the same issue while using macOS Mojave 10.14.6 and Mozilla Firefox.

BTW I have Dark Reader plug-in enabled in my browser, that's why the picture is in reversed colours. It doesn't affect the problem described.

Thanks.
