Firefox Support Forum

Hello Team,

I have installed Smart Card Minidriver on Windows Intel and installed firefox 64 bit version intel based. Mutual TLS is working as expected with Minidriver (Microsoft Base Smart Card Cryptographic Service Provider). Tried to use PKCS#11 dll and it is also working.

In the same way,

I have installed Smart Card Minidriver on Windows ARM64 and installed firefox ARM64 bit version ARM based. Mutual TLS is not working as expected with Minidriver (Microsoft Base Smart Card Cryptographic Service Provider). But when tried to use PKCS#11 dll and it is working.

I have questions here:

Firefox ARM64 on Windows ARM is not working mutual TLS with Microsoft Base Smart Card Cryptographic, Service Provider, Is this supported?

This is a Question for the Developers, and other Hackers!! Video Streaming Not Playing (Disney/Hulu/Prime/Vudu) Anything that uses Digital Rights Management (DRM) Content... YouTube works fine.. oddly..

I troubleshooted Resets,clearing cache, spoke to support from Disney on the phone, and finally reinstalled windows. Everything works.. Then applied my drive space hack. And everything is broken again.. Simple Hack, got the idea from Linux. I changed the C:\Program Files & C:\Program Files (x86) into Hard-links/Junctions to the D:\Program Files & D:\Program Files (x86).. And now the videos will not play... There must be some coding that monitors the Drive letter, maybe for pirating protection, I have no Idea... But I'd love to at the very least know why this happens.. I will plan to upgrade my SSD in the near future to prevent the need to move Program Files, It's just really annoying that a simple thing like steaming is now broken because the programs are installed on the D: Drive... Like WTF is going on.. Anyway, if someone has some incite into why, and a possible work around that would be great.

Thank-you very much if you read this!!

I have a couple of computers that are not allowed to have full access to the internet.

I've added the following URLs to the whitelist on my firewall:

aus5.mozilla.org and mozilla.org.

So far the only thing that has happened is the browser is able to tell that a new versions available but it's stuck downloading the update with zero progress.

I've seen some five or seven year old posts that claim I have to have the following URLs whitelisted:

aus.mozilla.org aus2.mozilla.org aus5.mozilla.org ftp.mozilla.org archive.mozilla.org download.cdn.mozilla.net mozilla.org mozilla.net mozilla.com

But since these are from a 5+ year old post I would like to know if these are still valid? And if not then what URLs are valid?

Screen popped up suggesting to refresh firefox. Did so 2nd time it appeared. Now home page is radically different and bookmarks are no longer visible. There is a pulldown screen for bookmarks but some had been deleted ages ago and others used daily are no longer there. Did the "about:profile" process and opened a fold and it has a folder marked "bookmarks"

How do I recover all the bookmarks and have them displayed as previously (vertical listing on left side). Never had anything like this happen previously.

when playing a video on youtube a mute button should appear when hovering over the tab when language is hebrew, this sign appears always, being on top of the website icon

The browser now and again fails to connect to all my sites randomly. I have tried a firefox refresh which worked for a while however now it has gone back to the same problem. All of my sites load on other browers. The bookmarks, history and pocket tab has disappeared from the browser. Can you please help with this problem?

Hi I am running latest firefox on windows 10. After a google search I have to put the view to full screen or move the window to see all the options on the right like 'tools' which I use a lot to limit to UK and the last year. is there any way to notice the window isn;t full size and the optios display should be made smaller or put into 2 lines?

1. Drop down to select the question. In search engines, when entering text, there is usually a text prompt to choose from, but I cannot select it 2. Verification code issue. The verification code usually swipes to the right after input, but cannot be moved at all! 3. Video acceleration issues. On video websites, it used to be possible to right-click to indicate video fast forward, but now there is no response after operation

My English is not good. Could you please write something simple and easy to operate so that I can translate correctly? Thank you

When printing emails, the content in the preview pane comes up with empty spaces and won't show the actual content of the email to be printed. A simple one page turns into three pages. I have tried other browsers to narrow it down to a Firefox issue. I have tried all the "fixes" in the community that I have found and still nothing works. I have cleared my printer default about:support page as well. Please help! Attached is are three pictures. The first is a Fedex page I am trying to print. The second is the print preview that comes up with the first two pages showing how the content separates.

I had to reinstall Firefox and restore my bookmarks from an HTML file. After the restore, I found I could only copy a few of my Bookmarks Toolbar and Other Bookmark links to the corresponding files in the new installation. I was only able to move the Toolbar bookmarks to the proper file because the old Toolbar file appeared on my toolbar, and I could move the bookmarks one by one to the toolbar until all were entered.

I'm faced with a similar problem with the Other Bookmarks (OB) file. I only have five or six bookmarks in the file, and I need to add about a dozen more. I tried copying and pasting them into the new file in the Bookmarks Manager; the bookmarks copied but would not paste into the file. (I know they copied because I successfully pasted them to a LibreOffice document.) I tried opening one of the copied links; it said it was in the OB file, but it wasn't listed. Why can't I just bulk-copy the bookmarks into the file in the Bookmarks Manager? If that isn't possible

I am using an outside application (1) that starts another application (2) on my computer. I already have the admin console for (2) open in Firefox. When I activate the application from (1), it sends a command to open up another tab with the exact same URL in Firefox. Its really more of a nuisance than anything, but I would like to make Firefox just defer to the existing tab since the URLs are the same. Not sure if this is possible, but it would be great if it was.

Thanks!

Subject: Issue with Video Playback on Firefox

Dear Support Team,

I hope this message finds you well. I am writing to report a recurring issue I have been facing with video playback on Firefox while using WhatsApp Web. Whenever I attempt to play received videos on WhatsApp Web through Firefox, I encounter an error message stating "The video cannot be played." I have attempted various troubleshooting steps to resolve this issue, but unfortunately, it persists.

Here is a summary of the troubleshooting steps I have taken:

Ensured that I am using the latest version of Firefox. Confirmed that media playback technologies like HTML5 are enabled in Firefox. Disabled all browser extensions and add-ons to rule out conflicts. Checked and adjusted browser video playback settings. Cleared browser cache and data. Despite these efforts, the problem persists, and I am unable to play WhatsApp Web videos on Firefox. This issue is particularly inconvenient, and I rely on WhatsApp Web for communication.

I kindly request your assistance in resolving this matter as soon as possible. If there are any specific Firefox or WhatsApp Web settings that need to be adjusted or if there is any additional information you require from me, please do not hesitate to let me know. I am eager to have this issue resolved and appreciate your prompt attention to it.

Thank you for your assistance.

Sincerely, Reza

I have two email address for @lostvalley.movie on Office365 through Go Daddy. One works fine but the other has authentication error. I receive fine but can't send.

The settings all match.

I tried all fixes mentioned from other users but no go.

My userChrome.css...

#main-window { border: 5px red solid !important; }

It's only half-working though as in first screenshot. I've tried messing about with padding & margins - to no avail.

The 2nd screenshot zooms in on bottom-left corner and shows a faint blue outline (shadow?).

Any suggestions on fixing the border?

Cheers.

I just filled all of this out. When I clicked on Submit everything disappeared and the boxes are now red. Really, I have to go through all of it again. Oy! The box with applications for my downloads used to have one or two or three. Now it has this; irc ircs JPEG Image mailto Microsoft Excel 97-2003 Worksheet Microsoft Excel Comma Separated Values File (application/ms-excel) Microsoft Excel Comma Separated Values File (application/x-csv) Microsoft Excel Worksheet Microsoft Word 97 - 2003 Document Microsoft Word Document ms-phone ms-settings ms-word onenote PNG Image Portable Document Format (PDF) Scalable Vector Graphics (SVG) spotify WebP Image zoommtg

What is Word 97-2003 doing there? Why is my phone an option? I didn't give Firefox my number. That's one problem. This issue makes my skin crawl. If I have to fill out a form on a new website all I have to do is type J and my full name, all of my email addresses, my physical address, and phone number appear in little boxes below the lines of the form. This is new and i really don't like it. Why, out of nowhere, is my information avaiblabe on the entire internet? If I hit Submit and these boxes turn a new color I will start screaming.

In the SharePoint library Setting is the desktop App defined to open M365-files. Chrome, Edge and Opera, open the files in the desktop App. Not so Mozilla Firefox: with this browser, the files are opened in a Tab, instead of the desktop App. Why is that? How can I change this behaviour?

It did'nt change with marking "Ask, how files are opened or saved With kind regards, Christian

I disabled all extensions today to troubleshoot a website and all of my Firefox container data is GONE!

Luckily, I have a second computer with Firefox that was synced earlier today before I did this.

I have put that computer #2 into airplane mode and have not opened Firefox in fear that a new sync will overwrite the data.

So far, I have saved "containers json" and "cookies sqlite" from computer #2 profile folder

Then, I backed up "containers json" and "cookies sqlite" from computer #1 profile folder (this is the computer I'm using now with the broken containers)

I have placed "containers json" and "cookies sqlite" from computer #2 and overwritten them on computer #1

The container names are back, and some of the containers remember the site logins, but some don't, and none of the websites will open in the specifically chosen containers from before.

Is there a way to restore the sites that were logged in and which sites auto-open with the specific container?

Thank you in advance
