Diễn đàn hỗ trợ Firefox

Up until 2 days ago, I had no issues accessing my yahoo email accounts (sbcglobal.net through At&T) I had done nothing different re settings. I rebooted my modem and my computer several times. I deleted old history which I do several times a week anyway. I called AT&T support team but they just suggested logging on to another browser. So I tried Edge and was able to access the emails successfully. I even "refreshed" Firefox and nothing changed except I had to replace several quick links. I checked for updates and discovered my Firefox browser is up to date. My Android cell phone has no issues with the emails. I have one on Firefox browser and one with Chrome on my cell phone and no issues with either one. I have been using the same log in link for many years. I even explored the new way to log in called "Currently.com" for yahoo mail. Still won't work on Firefox. But it does work on Edge. I would prefer to continue using Firefox for browser but need to use Edge til I figure this out. Any suggestions would be greatly appreciated. (BTW wifi IS on and the connection for everything else works fine.

Here is the message I get when I try to log in: "Something's gone wrong We may be having trouble with your connection. Connecting your device to Wi-Fi could help fix the issue or try again later.

Recently I have had several experiences with captcha when paying for something with a credit card. I check the box saying I'm not a robot, get a green arrow, but then the purchase does not go through. Error message says I failed to satisfy the captcha, even though I was never shown the grid of images. Just now I tried the same operation with the same company invoice using Chrome, and it went through successfully by just checking the box I'm not a robot. This is very inconvenient.

Hello,

Suddenly some UI elements became color-inverted or almost completely black, such as the tab icons in the tab bar, the website icons on the New Tab page and some icons in the settings menu. Also, some websites appear to have this issue, but the Samsung website is the only one I found so far with this issue.

On the same day it happened I switched to an OLED HDR-capable monitor, so I assumed it would be related to HDR, but I played around with some settings and I'm not sure anymore.

What I tried: - hardware acceleration on and off - HDR completely on and off - default light theme and dark theme, no customs themes installed - all extensions disabled (I have no extensions that would influence graphics or colors anyways) - latest update already installed - nothing else changed in the Nvidia control panel as far as I remember

None of the above helped. Any advice on this is appreciated. Attaching some pictures with the issue. Using Windows 11.

Thank you!

I've recently done a clean reinstall of Windows 11 and have noticed that, only for Firefox (134.0.2, build ID 20250120135430), a few videos playback without any audio, yet the same videos play with audio when using edge as a comparison. Most (if not all) of these videos did play with audio in Firefox prior to this reinstall.

Firstly, I'm pretty sure this is not a windows sound mixer issue since many videos on the same page and tab play back with audio just fine in Firefox. The same goes for it not relating to the Firefox setting 'Speaker selection', under (burger) > settings > privacy & security > Permissions because videos of different formats (or using different players) on the same page play back audio fine. The tab is not muted. Again, some videos on the same browser tab play audio fine; some of a particular format or player only play the video, while missing the audio (and where Edge plays the same video with audio).

Another common and potentially relevant issue I've seen is that, this being a 'Windows 11 N" install, it was initially missing the settings > system > optional features > Media feature pack, but that is now something I've successfully added. I should add that windows did report problems when I initially tried to add the media feature pack but, after a very long delay, it eventually appeared to succeed when I ran a couple of DISM incantations that I think ended with - "dism /online /add-capability /capabilityname:Media.MediaFeaturePack~~~~0.0.1.0"

I have the 'Play DRM-controlled content' setting enabled.

Comparing the Firefox vs Edge video playback on this video test page - https://tools.woolyss.com/html5-audio-video-tester/ I get the following results (don't know how to get it formatted/aligned correctly, sorry) -

                           FF vid    FF audio    Edge vid    Edge audio
av1-opus-sita.webm          Works     Works       Works       Works
vp9-vorbis-spring.webm      Works     Works       Works       Works

avc-mp3-sita.mov            Works     Works       Works       Works

And perhaps also relevant is that there's also a difference in the audio-only samples further down the table on the same page -

                   FF audio   Edge audio
audio-sample.mp3    Works      Works
audio-sample.weba   Works      Works
audio-sample.ogg    Works      Works

ac192.mp3           Works      Works
spoonradio-hd.aac   FAILS      Works
audio.opus          Works      Works

Also, every 'v.redd.it' / reddit-video-player video plays the video fine but has no sound when using Firefox but plays both sound and video fine with Edge. Here's one for example - https://old.reddit.com/r/funny/comments/1i7y1nr/rock_paper_scissors/

I've seen lots of similar (but not identical) issues on Firefox video with no audio problems with suggestions a few things to try. In addition to what I've already mentioned above, I've tried the following without success -

- Restarting Windows - Restarting Firefox - Restarting Firefox with addons/extensions disabled - 'about:support' > Refresh Firefox - 'about:support' > Clear startup cache - (hamburger) > more tools > task manager > (click the little profile icon for the page playing the video) - I've checked the settings suggested here: https://support.mozilla.org/en-US/kb/fix-common-audio-and-video-issues#w_check-some-firefox-settings

I realise it may be possible to side-step this problem by flailing around with more drastic work-arounds like trying a clean re-install of Windows or a full uninstall and clean of Firefox, but that doesn't really help figure out the problem, which leaves the possibility it could easily happen again to me or others when it might be something that can be more properly fixed or guarded against in Firefox itself, so I hope someone can suggest what might be done to home in on identifying the cause of the problem and so learn whether a more precise fix can be employed.

I downloaded a PDF and used Firefox to view the file. I'm trying to find key words in the PDF and I always get phrase not found. As a test I inputted a word I found in the document but find in page stated phrase not found. What am I doing wrong? I remember that I have used that feature in the past and it worked.

A video of what is happening . This only happens when I search something up, for example, if I search more than one thing up on Pinterest, Google and sometimes Youtube . . . I'm sure it's not related to any extensions, the only one I installed recently was Privacy Possum, but after noticing this issue I deleted it and it didn't resolve the issue.

iCloud has stopped signing in on the Firefox browser for Windows. I contacted Apple Support and they told me that this is an issue on Firefox's part, and told me to try signing in the next morning and they guarantee it'll work. It did not. In fact, it has been over a week, and it still does not work.

When I enter my Apple ID and Password, the website gives me an error "Failed to verify your identity. Try again." The website does NOT send me to the 2fa screen, yet it still sends a 2fa code to my iPad nonetheless.

As Apple has said this is an issue on Firefox's part, I am posting this here. Attached is a screenshot of the error.

Hi Win10 PC fully up to date. Changed my printer from a Xerox to an HP laser. In the control panel, set the HP as the default printer. MS Office prints on the HP without prompting. Firefox (134.0.2) always defaults to the Xerox. The HP is available in the drop down box. Restarting the PC or reloading Firefox makes no difference, Firefox always defaults to the (non existent) Xerox. MS Edge defaults to the HP. Any ideas? Regards - Andrew

Hello,

I use Screen Time to block sites on my Mac, running Sequoia 15.1.1. For some reason, it recently (within the last 2 weeks or so) stopped blocking sites on Firefox 134.0.2, but not on Safari.

Is this a known issue? Is there a solution?

Thank you for your help.

I've used Firefox for many years. The past month or so weather radar doesn't come up on multiple weather sites, pages are slow to load or don't load, getting error codes on video's, pictures don't always load, and many other problems. I uninstalled Firefox and re-installed the current browser and I still have all these problems. I'm having to use another browser now. I run Windows 11 on my PC.

Hello mozilla support team I am Gina I have this problem for about two or three weeks now.I try to watch videos on mozzila firefox and I get gliches and sound dose'nt work.I don't have those problems on vivaldi at least at this moment. I realy hope you can solve those issues. Kind Regads! Gina Monica Ciuca

my new monitor offers a screen where I can shut down, sleep, or restart.......I usually chose sleep, because I think it allows me quicker access to my browzer home page when moving the mouse for reboot. However, about six or more times now, the sleep mode will stop, a "don't interrupt" message in ghost script in the upper left hand corner of the screen comes on, the an HP logo with a dizzing circular moving gif suggest the computer is starting........no so. I have waited 30 minutes or more, started and stopped with the power button, hit every key on the board and swear prolifically now and then with NO results.

Using a fairly new HP computer, win 11, and version 134.0.2 of FireFox......AND, I'm a good guy. I think so, anyway. What am I doing wrong. It seems that each time this happens, if and when the computer will restart, that FireFox has an update in the wings and needs to have that installed before I move on to use the pc. Is there a connection?

I use Firefox 134.0.2 (64-bit) on Ubuntu 24.04.

Some (not all) web sites show up only after a delay of exactly 30 seconds. The attached screenshot shows that this delay is due to DNS resolution. This behavior is reproducible by simply closing Firefox, opening it again and entering the same web site once more. Once this initial delay of 30 seconds for DNS resolving has passed the web site can be browsed normally.

Using Google Chrome, Opera or even the Tor Browser on the same system works without any significant delay. Also a DNS lookup from the console returns data almost immediately.

As the delay is always exactly 30 seconds this looks like some DNS resolver timeout only showing up when using Firefox.

Neither starting Firefox in Troubleshoot Mode nor (as often suggested) disabling IPV6 for DNS by setting network.dns.disableIPv6 to true did help.

Any idea how to fix this 30 seconds delay?

Many thanks for any help, Felix

On several web pages, when i try to log into the accounts i have on those websites or account creations, when i try to click "Continue" or "Log in" or what ever may be the case to actually finish the process, the button will not actuate. I have tried on Microsoft edge and it works with no notable issue.(It just is slow because its Edge. lol) I dont have an adblock going of or anything of the sort that appears to be blocking the operation. Please heeeeeeelp.

Recently starting having the issue where some whites and the tab icons appear washed out and even glitched out and pink when using my PC. I haven't made any significant changes to my system as far as I recall.

Colours in other browsers and applications are effected. Going to the same webpage on both Brave and Edge shows the whites correctly. On all the games on my PC there are no glitches in colours.

I have tried a few fixes already: -Removing and re-downloading GPU drivers - Fixes the issue temporarily. After about 1 day the issue comes back. -Re-seating the GPU - No fix. -Turning off colour override in Firefox - No fix. -Uninstalling and reinstalling Firefox - No fix.

If anyone has an idea or knows the setting that may be causing this problem I would really appreciate it.

Hello to you up there ! I have Windows 11 - 23H2 up to date ! since 21/1/2025 each time I start Firefox (up to date 134.02 - 64 bits) I get a warning from Malwarebytes Browser Guard that blocks a outgoing request coming from Firefox via port 443 to the IP 82.221.136.1 ( = welcometothemachine.co …. what is that ?? analytics ? AI  ??) .... I am asking myself why is Firefox trying to go to that IP because I never did ask for something like that and how to delete the whole request every time now .... (CCleaner does nothing when used) ... bizarre bizarre behaviour yes ! Who can answer me. Can you please also answer me on geomar@scarlet.be because I would not like to miss the answer ? Thanks.

Starting early this morning I could not open a website (where I purchase supplements) I have accessed in the recent past. I added the address to the DNS listing but that didn't help. In the verification lock icon in front of the address it says the connection is secure. But below it states the Connection verified by a certificate issuer that is not recognized by Mozilla. Prior to 1/22/25, I had no issues opening this or other websites. It doesn't matter if I have my VPN turned off or not, the website does not open. Was the Mozilla update of 1/22 the cause? If so, how do I rectify the issue I currently have? If not, how do I rectify the issue I have?
