https://goinbali.com/ my website is still on development, but I can't open it using firefox. But it work on Edge and other chromium based browser. Already did : - disable ublock origin - updated to FF latest version

MP4 Not loading:

I have uploaded a few MP4 animated images to our website, but they are not loading in the Firefox browser. It looks like they are getting corrupted. This issue only occurs in Firefox. I’ve also attached screenshots for reference. Can someone help me understand why they are loading like this?

When I open FF 137 on my iMac running OS 12.7.6, it just keep trying and trying with no link. When I try and quit it needs to be forced quick to stop running. There are no fire walls and it worked yesterday 4-5-25 just fine, but no go today. I tried replacing FF and still no luck, what do I try now, [email removed]@yahoo.com

Hello, I use Windows 10, I downloaded Firefox using Microsoft Edge. Once it is installed, it creates an Icon then when you double click it, it does not open, even when I try to open as administrator and it opens, it does not look like a Firefox page because it is a blank page. My browser is Opera, but I opened Firefox from Microsoft Edge. Email me at [email removed]@yahoo.com please.

Why are these showing up now? They were never there before. Is there a way to hide them or make them disappear? They are ugly, distracting to look at and unnecessary. I tried one about:config solution, but it did not work. Please fix this. See screenshot. The black tacks should not be visible, but now they are.

I'm attempting to set up Firefox in a newly installed OS and have logged into my Sync account. Many aspects seem to be loaded in, but the status via the Settings is stuck at "Syncing..." despite waiting several hours. Quitting Firefox results in a crash window popping up.

There are no files in the weave/logs directory. The weave/failed directory has multiple json files; most almost completely empty. addons.json has an ID, but that's pretty much it.

Deleting the .mozilla directory and starting over yielded no change in behavior.

Any help would be appreciated. Thank you.

Firefox launch opens /home/pdl/Documents/Browsers/Firefox/chrome as a new tab, I have set the setting "Open previous windows and tabs" on and off, I prefer this setting to be enabled, my OS is LMDE 6 and Firefox is the flatpak install version 137.0.2 (64-bit), I have also tried the system install and deleted all Firefox in between installs or should I say I think I did, please this is driving me nuts, even with me logged out of Sync this happens.

Thanks

I am following the procedure outlined here at:

https://support.mozilla.org/en-US/kb/install-firefox-linux#w_install-firefox-deb-package-for-debian-based-distributions-recommended

I get this error when I run the gpg command

2:05:29:490 1>#8 [base 5/8] RUN gpg -n -q --import --import-options import-show /etc/apt/keyrings/packages.mozilla.org.asc | awk '/pub/{getline; gsub(/^ +| +$/,""); if($0 == "35BAA0B33E9EB396F59CA838C0BA5CE6DC6315A3") print "\nThe key fingerprint matches ("$0").\n"; else print "\nVerification failed: the fingerprint ("$0") does not match the expected one.\n"}' 22:05:29:567 1>#8 0.285 gpg: keyblock resource '/home/.gnupg/pubring.kbx': No such file or directory 22:05:29:567 1>#8 0.285 gpg: no valid OpenPGP data found.

I am not familiar with Linux and I thought that following the instructions would work so I am asking for help.

Here is the complete script.

Thank you.

When accessing Outlook (https://outlook.office.com) using Firefox ESR version 128.9.0 and attempting to download a file attached to an email, the string 'UTF-8' is automatically inserted at the beginning of the file name, which is causing issues. This phenomenon does not occur with other browsers such as Edge or Chrome.

Is there a way to solve this problem?

This issue came up in early April 2025.

Programs other than Firefox (e.g. Edge, Media Player) behave normally: when playing sound, if nothing is plugged into the 3.5 mm jack, the sound comes from the desktop's external speakers; and when an audio device (speakers or headphones) is plugged into the 3.5 mm jack, the sound instead comes from that device.

Where as Firefox will play using the internal speakers as expected, but when a device is plugged into the 3.5 mm jack, no sound signal goes to that device.

It seems then that the hardware is okay, and the problem must lie within Firefox, or within a Windows setting that is very specific to Firefox.

The sudden onset earlier this month may point to either a Firefox update, or (less likely) a Windows update.

The Widevine Content Decryption Module failed on both our Windows 7 PCs. Version: 4.10.2891.0 Last updated Apr 2, 2025 when our version of Firefox was updated. The current version is 115.22.0 est (64-bit) (Streaming is OK on my Mac using Safari and Chrome; don't have Firefox installed there)

Over recent months, there have been quite a few reports of this issue on several operating systems. Our viewing of videos only failed us on April 2nd or 3rd, 2025, not previously. This seems to be occurring at various times in various systems. Solutions are not accessible to lay folks, and Google is inaccessible! Can anyone help us? Thanks

Sometimes when watching a video on hulu (and maybe other similar sites) after a commercial the screen is all messed up and I have to stop the video and reload to get a picture. The sound is fine but the picture is messed up. This only happens with firefox. Any ideas on how to fix this?

Hello,

I never received a confirmation code to sync with my other computer. I've tried to followed all the instruction per request, still no avi.

I've followed below instruciton from your team:

   Search your inbox for emails from accounts@firefox.com with the subject line "Confirm your account". Be sure to also check Spam/Junk folders.
   Add accounts@firefox.com to your whitelist/address book. After that you, will need to trigger another confirmation email by trying to sign into your account again.
   Check that you’re using the correct email address. Very often the email you’re trying to sign in with is not the email the account was created with.
   If you're using an email application to check your inbox, try using your email provider's website instead, or vice-versa.
   Disable any VPN or special DNS configuration when attempting to sign into your account

Yesterday, the Firefox quit working. Today my connection was verified by Fios and during the phone call, we tried Google Chrome (Yuck!) and it worked on the internet. I have downloaded the latest Firefox and it still does not work. Is there a problem with Firefox? Should I delete Firefox and reinstall?

I'm using Windows 10 and have just completely uninstalled and reinstalled Firefox.

PROBLEM: Using MS Office 2021, OUTLOOK, when I select "EMAIL LINK" I get two windows, the expected one with the email link in the body, and one much smaller that is blank.

The second smaller window is an extra and serves no purpose; except that I have to close it. After an hour with a senior Microsoft tech this morning, he said the problem with with Mozilla; that everything works normally (only one window opens!) - leaving Firefox/Mozilla as the source of the problem

I've completely uninstalled and reinstalled Firefox, clearing the cache, etc., etc. so I have nothing to attach. ALSO, when I tried to "Share Date," there was an error and I 've had to retype the above again. So, if you need more that the info I've given, please let me know.

how many times do I have to say YES to the update question that constantly appears each time I access another page? I said YES the first time. It is driving me NUTS and interrupting my work

Created Gmail account for gmail.com.

Where my name or initial should appear, it says "Finish setup"

I have checked circles that I want, but it still says "Finish setup."

What can I do?
