Firefox Community Forum

I was sent an email so I could reset my password, and Firefox said I was using windows 10, when in fact I'm using windows 11, unfortunately. Is this a bug? What gives?

In Firefox, I have audio and video autoplay blocked globally, and added an exception for one particular website (Discord). However, Discord now only autoplays videos once, but doesn't loop them as it should (they implemented GIFs as videos, but now they don't loop).

Of course this could be interpreted as a bug in Discord's web client. However, there shouldn't be a difference between a website that got an exception and autoplay being globally allowed. Therefore i suspect that there is a bug in firefox where some property, state, or hint is set differently depending on whether a page has been added to exceptions or autoplay is allowed globally.

Is there anything i can do to work around this? I really want an autoplay exception to actually work as expected (the website doesn't need to know that it's special)

Hi Firefox Team,

I wanted to ask, whether you know any solution to my streaming problem. I noticed that my download speed is incredibly fast, when I am running a download in the background of my PC. This can be a windows-update or updating a game via steam. But when I am not downloading anything, then Youtube cant even stream 360p without buffering every 10 seconds. I feel like the Firefox-Browser is not telling my PC that it needs the internet and thus does not get it, but when another program needs internet, It gets enough to work.

It's very hard for me to find where to go after clicking on the three line symbol in right hand corner. But when I finally did locate in Settings the section on passwords and sign-in info I turned that off. I was happy until I again signed into Mozilla and Amazon and my email address (which I use for ID) continued to pop up. Why do these things have to be so hard to find and then to make work. Please help. Thank you.

Well being an OAP I needed new laptop. Always used Firefox browser but finding it difficult to get restarted. Had to opt out of window s to even download. Apparently I can transmit(?) my existing passwords etc from one laptop to another is this correct? Only basic computer knowledge but trying hard !! Karen x

I read online that Firefox is planning on implementing AI features. Given the track record of AI in other browsers leaking private information, bogging down connectivity, and generally being a nuisance towards users, I was wondering if there will be opt out features in future updates? Or know of forum threads that will update with tutorials on how to turn off AI features?

If not, does anyone on this forum have recommendations for no-ai browsers?

Context

While playing YouTube videos in Firefox, intermittent crackling appears after a few minutes of playback. This report documents detailed testing that demonstrates the issue is not related to the DAC, USB interface, or system hardware, and is exclusive to Firefox.

2. System Configuration

CPU: AMD Ryzen 5 5600X @ 43 °C

RAM: 64 GB DDR4 dual-channel (16-20-20-38 @ 1572 MHz)

Motherboard: ASRock X570 Phantom Gaming 4 (AM4) @ 54 °C

GPU: NVIDIA GeForce RTX 3050 (audio drivers disabled, audio hardware off)

Monitors: LG HDR WFHD 2560x1080@60Hz and IPS236 1920x1080@60Hz

Storage: Multiple SSD and HDD SATA drives (500 GB – 2 TB)

Audio: Realtek High Definition Audio disabled; iFi nano/UNO DAC connected via USB with power filtering, using Exclusive Mode / ASIO

3. Tests Performed 3.1 DAC and USB Validation

Continuous playback of PCM 384 kHz/24‑bit and DSD256 via Roon/ASIO.

Duration: over 25 minutes of uninterrupted DSD256 playback.

Result: no crackling, pops, or errors.

Conclusion: DAC, firmware, USB cables, ports, and power supply are fully operational; heavy data load does not cause errors.

3.2 Browser Comparison

Chrome (YouTube, identical conditions): continuous playback without crackling.

Firefox (YouTube, identical conditions): crackling progressively appears minutes into playback, temporarily disappearing when the video is paused.

3.3 Isolation of Variables

USB motherboard ports and original drivers fully tested.

GPU audio drivers and hardware disabled.

Windows Shared Mode off, Exclusive Mode enabled.

Predefined audio formats set according to DAC preferences.

USB power management disabled.

DAC temperature stable; no overheating observed.

4. Technical Conclusion

Hardware: DAC, USB, cables, power, firmware, and GPU are not the cause of the crackling.

Operating System: Windows 11 is correctly configured; Exclusive Mode / ASIO works without errors.

Browser: Firefox is the only element consistently reproducing the issue.

Most Likely Cause: Firefox’s buffer management and audio sandboxing interacting with Windows, causing intermittent interruptions in audio flow.

Summary: All hardware and OS factors have been tested and validated: DAC, USB, cables, power supply, firmware, GPU, and temperature do not produce crackling. The only consistent factor is Firefox, making this a software-bound issue.

Engineering Note: This diagnosis conclusively demonstrates that the intermittent audio crackling on YouTube is caused exclusively by Firefox on Windows 11, independent of DAC or USB hardware. The issue should be investigated at the browser level, specifically how Firefox handles continuous digital audio streams and buffers on Windows.

Mozilla Support reports wrong version of windows? I have a screen shot. The web site reports win 10 when I have Win 11 Pro. The version check on this support page reports the correct information. So Mozilla website itself is out of date?
