I use eBird extensively. When I try to play the audio (with sonograms), I get a message that says "We are still processing this file. Try again later". These files perform well on my Android phone, so I know it it is not eBird's glitch. I am confused about the setting options on Firefox that I need to set. These files are usually .wav format. I have tried to open a ticket with eBird, but have not had a response. Can you guide me? Thanks.

Firefox for Android 150.0 Build 2016155439 OS Android 16 Autoplay set to "Block audio and video" but audio and video still autoplay from NPR.org website started happening a few weeks ago Is there a way to fix this please?

thank you

I'm not sure when it started happening, but whenever I'm watching something full screen, or just full screening, Firefox on Mac, there's this thin white line at the top of the window that's very distracting. Has this been happening to anyone else and does anyone else know how to get rid of it?

Good afternoon

recently i tried just realise my firefox can't played HEVC streaming video like twitch etc. (1st pictures)

i check on other browser such as Chrome, Edge, etc. it's played normal i check on google all about config

like media.wmf.hevc.enabled , media.hevc.enabled , dom.media.webcodecs.h265.enabled all set to true. checking on about:support i found it's not supported (2nd screenshot)

i check on Powershell are like this :

C:\WINDOWS\system32> Get-AppxPackage | Where-Object {$_.Name -like "*HEVC*"}

Name  : Microsoft.HEVCVideoExtension Publisher  : CN=Microsoft Corporation, O=Microsoft Corporation, L=Redmond, S=Washington, C=US Architecture  : X64 ResourceId  : Version  : 2.5.33.0 PackageFullName  : Microsoft.HEVCVideoExtension_2.5.33.0_x64__8wekyb3d8bbwe InstallLocation  : C:\Program Files\WindowsApps\Microsoft.HEVCVideoExtension_2.5.33.0_x64__8wekyb3d8bbwe IsFramework  : False PackageFamilyName : Microsoft.HEVCVideoExtension_8wekyb3d8bbwe PublisherId  : 8wekyb3d8bbwe IsResourcePackage : False IsBundle  : False IsDevelopmentMode : False NonRemovable  : False IsPartiallyStaged : False SignatureKind  : Store Status  : Ok Capabilities  : inProcessMediaExtension,

                   uniqueAppPackageCapability

in summary it's installed and running.

i will be happy if you can guide me on how to enable it. because tbh Firefox are my daily drive

thanks before

For the past.. month I would say, any time I try to use Youtube on my Firefox Browser it nearly always switches over to landscape mode after watching a video. It doesn't matter whether my phone screen's auto rotate is on or off it still does it. Yes. I already tried to turn my auto rotate on to switch it back to potrait mode, it still won't work. The only solution I currently have is closing Youtube all together from my Browser, which really REALLY sucks!!

Can someone PLEASE look into the glitch?!

Hello there.

Since last update i'm unable to browse websites like youtube, social media and all other websites with video content. Video often fails to load,the wholewebsite is not loading, freezes while played or while exiting full screen mode. All of these freezes the browser - the site cannot be refreshed, links does not work. The only way is to close the tab with the freezed page or kill the Firefox process in windows Task Manager. Refreshing, re-installing, deleting or using different profile don't work. Same with add-ons. Seems like the issue lies within the browser and it started to appear since last update.

Speakers are not muted. When I play a youtube video in Firefox I don't hear anything but if I play the same video in Chrome it works fine. I really prefer Firefox but I occasionally need to use my browser for Teams meetings and the audio doesn't work.

The taskbar (the one with the Start menu) doesn't hide when watching videos in fullscreen mode. This happens on YouTube as well as on any other website. The problem disappears if I run the browser in Safe Mode. It's only Firefox that doesn't work — in Chrome the taskbar does disappear.

When using Firefox to access Netflix the video is distorted/greyed out in HDR mode, but displays properly using Microsoft Edge. None of my other streaming services experience this issue. How do I get Firefox to properly display Netflix in HDR mode?

Netflix customer service sent me here.

Lately, whenever I click into a youtube video from within youtube, instead of Firefox blocking autoplay, it mutes the video but lets it play.

Initially, it was muting EVERY video I pulled up, but messing with my settings has fixed the problem if I click into a youtube video from elsewhere (ex. a google search result), or if I refresh the page. It's super annoying to having navigating youtube be this non-functional right now, though, since everything just silently plays until I catch and unmute it! Any help would be super appreciated!

(I'll attach an image with my current autoplay settings.)

While playing YouTube on firefox I tried to pull down the full screen. Rather going full it stayed same small and rest screen becomes dark . After pulling many times I finally find it full screened. But it happens everytime same after changing video or going back.

Is anyone else having problems manually playing videos after selecting Block Audio and Video in order to prevent videos from auto playing? I got sick of videos starting automatically every time I navigated to a web page, so I followed the instructions to disable auto play by selecting Block Audio and Video in the settings. Now, when I try to manually play a video, it fails to start. Any suggestions on how to resolve this issue while still preventing videos from autoplaying? BTW, this is occurring on iPad and iPhone rung the latest iOS version.

не скрывается панель задач(панель с меню пуск) при просмотре видео в полноэкранном режиме. не работает как на ютубе так и на любом другом сайте. проблема исчезает если запускать браузер в безопасном режиме. не работает только firefox в chrome панель задач пропадает

As of around 6 weeks ago (bit of a guess) I no longer have the option of pausing/playing media on a tab from the tab list. For at least the last few years prior to this issue, whenever I had a tab playing media (mostly video, but sometimes audio e.g. a podcast episode on BBC.com) there would be a small pause button for that tab in the tab list.

I've attached a attachment (2 screenshots merged). The tab with the purple circle is currently playing a MP4 video (streamable.com) and I would usually see a pause button, I think where the circle is located but might have been in a different corner.

I found this Reddit thread which mentions the issue but outside of the 2 people in this thread I have not found any other info or reports. https://www.reddit.com/r/firefox/comments/1rh5gcy/youtube_buttons_playpause_missing_in_android/

Additional info: while playing video, I am able to pause through system notification (see image attachment) so the playback IS recognized. But no pause/play button in tab list.

Hello Firefox Support Team/Forum

I am writing to request guidance on a hardware video acceleration issue that I have been unable to resolve despite extensive troubleshooting. Firefox appears to be blocking VA-API hardware decoding on my system even though the VA-API stack is confirmed working at the system level. — SYSTEM SPECIFICATIONS — OS: Arch Linux (rolling), kernel 7.0.13-arch1-1 Desktop: Hyprland 0.55.4 (Wayland, DRM backend) CPU: AMD A9-9425 (2 cores, 3.1GHz, Excavator architecture) RAM: 8GB Firefox: installed via pacman (native, not Flatpak) Mesa: 26.1.3-arch1.2 GPU setup (dual): • card0 / renderD128: AMD Stoney R5 Graphics (iGPU) — VA-API confirmed working here • card1 / renderD129: AMD Hainan R5 M435 (dGPU) — used by Hyprland for display output — CONFIRMED WORKING AT SYSTEM LEVEL — Running ‘vainfo’ on the integrated GPU (renderD128) confirms the following profiles are available: VAProfileH264ConstrainedBaseline, VAProfileH264Main, VAProfileH264High (VLD + EncSlice) VAProfileHEVCMain, VAProfileHEVCMain10 (VLD) VAProfileMPEG2Simple, VAProfileMPEG2Main, VAProfileVC1 (VLD) VAProfileJPEGBaseline (VLD) MPV with ‘–hwdec=vaapi-copy’ successfully hardware-decodes H264 locally, confirmed by ‘nv12’ pixel format output and reduced CPU usage. radeontop monitoring card0 (stoney, bus 00) during Firefox video playback shows: • Graphics pipe: ~53% (compositing activity) • UVD row: absent / 0% (no hardware video decode activity) • Memory clock: near 0.00G This confirms Firefox is NOT using the hardware decoder despite VA-API being functional. — FIREFOX DECISION LOG (from about:support) — HARDWARE_VIDEO_DECODING: default available / user force_enabled H264_HW_DECODE: default available (no blocklist) HEVC_HW_DECODE: default available VP8_HW_DECODE: env blocklisted — FEATURE_FAILURE_VIDEO_DECODING_MISSING VP9_HW_DECODE: env blocklisted — FEATURE_FAILURE_VIDEO_DECODING_MISSING AV1_HW_DECODE: env blocklisted — FEATURE_FAILURE_VIDEO_DECODING_MISSING DMABUF_SURFACE_EXPORT: env blocked — FEATURE_FAILURE_BROKEN_DRIVER WEBRENDER_COMPOSITOR: env blocklisted — FEATURE_FAILURE_WEBRENDER_COMPOSITOR_DISABLED Note: VP8/VP9/AV1 being missing is expected and correct for this GPU generation. The concern is that H264, which IS in the vainfo profile list and shows as ‘available’ in the decision log, is still not being routed to the hardware decoder in practice. — ENVIRONMENT VARIABLES IN USE — MOZ_ENABLE_WAYLAND=1 LIBVA_DRIVER_NAME=radeonsi LIBVA_DRM_DEVICE=/dev/dri/renderD128 MOZ_DISABLE_RDD_SANDBOX=1 — about:config SETTINGS CURRENTLY SET — media.ffmpeg.vaapi.enabled = true media.hardware-video-decoding.force-enabled = true media.hardware-video-decoding-vulkan.enabled = false media.rdd-process.enabled = true — WHAT WAS TRIED — 1. Installed full Mesa stack: mesa, libva-mesa-driver, libva-utils, ffmpeg, vulkan-radeon (64-bit and 32-bit variants via multilib). 2. Set LIBVA_DRM_DEVICE=/dev/dri/renderD128 to hardcode VA-API to the stoney iGPU and prevent it from accidentally targeting the hainan dGPU (which fails Firefox’s internal VA-API test with FEATURE_FAILURE_VIDEO_DECODING_TEST_FAILED). 3. Enabled media.ffmpeg.vaapi.enabled and media.hardware-video-decoding.force-enabled in about:config. 4. Disabled MOZ_DISABLE_RDD_SANDBOX via both ~/.bash_profile and hl.env() in the Hyprland Lua config to allow Firefox’s RDD process to access /dev/dri/renderD128. 5. Installed enhancedH264ify extension with VP9 and AV1 blocking enabled. YouTube confirms H264 (avc1.64002a) is being served. Despite this, over 1100 frames out of ~4200 are dropped during 1080p60 playback. 6. Verified with radeontop -b 0 (stoney, bus 00) during active 1080p H264 playback: the UVD block shows no activity whatsoever, confirming the CPU is doing all decoding. 7. Tested with and without gfx.webrender.all = true. Enabling it caused severe visual corruption (texture artifacts, split UI elements), so it was reset to default. 8. Did NOT disable media.rdd-process.enabled (correctly kept at true, as RDD is the process Firefox uses for VA-API decoding). 9. Confirmed Firefox is installed via pacman (not Flatpak), so there is no Flatpak sandbox layer involved. — THE CORE QUESTION — Given that: • vainfo confirms H264 hardware decode is available on renderD128 • H264_HW_DECODE shows as ‘default available’ in Firefox’s own decision log with no blocklist entry • media.hardware-video-decoding.force-enabled is set to true • MOZ_DISABLE_RDD_SANDBOX=1 is set • LIBVA_DRM_DEVICE explicitly points to the correct render node • MPV successfully uses vaapi on the same system …why is Firefox’s RDD process still not routing H264 decoding through VA-API, and what additional steps or logs would help identify the specific internal failure point?

Any guidance on enabling verbose VA-API logging within Firefox’s RDD process, or any known issues with AMD Stoney + Hainan dual-GPU setups on Wayland that might explain the DMABUF_SURFACE_EXPORT FEATURE_FAILURE_BROKEN_DRIVER blocklist, would be greatly appreciated.

Thank you.
