Android 版 Firefox コミュニティフォーラム

I default to a portrait orientation in my phone, when entering full-screen on a YouTube video Firefox automatically rotates the screen to landscape and then back again to portrait when exiting full-screen, that's great, however if I then change tabs and return to the tab where the video was playing (which is no longer in full-screen) Firefox rotates the entire site back to landscape mode. 100% reproduction rate. Temporary fix is entering and exiting full-screen again but the bug happens again if I change tabs subsequent times.

Device: POCO M6 PRO 5G Device Model: 23076PC4BI Android version: 15 AQ3A.240912.001 Firefox version: 147.0.3

Issue description: Firefox for Android stops playing audio and video in the background whenever I switch to a new tab or move the app to the background.

This happens on multiple websites such as YouTube,YouTube Music, Spotify Web Player, and other media streaming sites. As soon as Firefox is not in the foreground, playback pauses automatically. this issue persist in every media playing sites.

Steps to reproduce: 1. Open Firefox on Android 2. Play any video or music (for example on YouTube or Spotify web) 3. Open a new tab or switch to another app 4. Audio/video stops immediately

Expected result: Media should continue playing in the background, similar to other browsers or previous Firefox behavior.

Actual result: Playback stops as soon as Firefox loses focus or is sent to background.

Additional information: - Happens every time - Tried restarting phone and reinstalling Firefox - Battery optimization settings disabled for Firefox - Issue does not occur in other browsers

Hello! I've recently been having some issues getting videos to play in the background from Firefox's audio notification media player feature. I very frequently use YouTube in the Firefox browser so that I can then exit the browser and still play the audio of a video via the media player, but last night that media player stopped working for me. When I close the Firefox app, I still get the notification as usual, but tapping the "play" button achieves absolutely nothing. I've tried to search the issue and test some fixes myself, but nothing has worked so far. The fixes I've tried include:

• Activated "Allow video and audio" in the Firefox Autoplay setting
• Made sure autoplay was allowed in the YouTube browser tab
• Tried to play the audio while connected to wi-fi and while on data
• Checked for updates to my phone, YouTube, and Firefox (I am up to date)
• Deployed the old "turn it off and turn it back on again" fix, both in Firefox (closing all tabs and re-opening), and for my phone (shut it down and restarted it).

None of the settings for the media player or general notifications for Firefox seem to govern this issue, so I'm bringing it here. Thank you for taking the time to read through all of this. Please let me know if you have any suggestions for me! (I've included a photo of the notification bar for extra reference)

I am using Firefox on android and since the most recent update the app will no longer let me play videos in the background, in another tab or with the screen locked.

I'm using Firefox on my Android phone (model: Samsung Galaxy, Android version 14), and whenever I watch YouTube videos, the playback is choppy and lags every few seconds, even on stable Wi-Fi. This happens on both embedded videos and directly on youtube.com. I've tried clearing cache, updating the app to the latest version, and disabling extensions, but it persists. Videos play smoothly on Chrome. Any fixes?

Can't play (listen to youtube) after locking phone anymore. Can't listen to youtube in a different tab anymore. And still can't load comments on videos except youtube shorts

I'm having an issue were any video on firefox i watch automatically pauses. sometimes it takes a few seconds, sometimes instantly.

I've tried restarting firefox and my chromebook, deleting cookies & cache and reinstalling firefox. but nothing helped. It seemed fine for a bit after restarting my chromebook but than it started happening again. Turning off adblock just causes it to pause the ads.

If anyone has an idea of what to do that would be great!

When I go to the firefox website and tap on the microphone to ask a question the Google speech services comes up and I cannot adjust the loud volume on your settings or the phone Google settings. I have a Samsung Galaxy A25 5g phone and on Android 16. I have tried finelock sound assistant and that does not help. Is there an extension that Firefox has that I can use to adjust the volume when tapping on the microphone on Firefox?

I also have a Lenovo Tab M9 9" HD Tablet that has the Android 13 version on it and have no problem at all adjusting the microphone volume on that through the tablet setting.

Any kind of video playback is taking so much time and even if it is playing the video playback is not smooth at all. I have disabled all the extensions, deleted the cookies, using the latest version still things are working the same.

If I have a YouTube video open in another tab, when I switch back to that tab my screen will automatically become landscape mode and will not rotate to portrait mode. The video doesn't become fullscreen; it doesn't matter whether the video is playing or not. This happens even with auto-rotate turned off. The only way to get the tab back to portrait mode is to make the video fullscreen and then minimize it, after which auto-rotate works correctly again.

Firefox on android gets stuck in landscape mode after playing a video on YouTube. Usually this happens after exiting fullscreen but can also happen when switching to another app and back to firefox. Going in and out of fullscreen again usually fixes it, but you can't do that on shorts and it's very annoying. I tried to use a fix posted 7 years ago of going to about:config (which I had to go to separate settings and enable to even get there) and toggling media.videocontrols.lock-video-orientation, but that setting doesn't appear to exist anymore. Is there anything I can do to fix this?

When I'm on a long drive I need my YouTube playlist in the background because I need the navigator on screen, sometimes the autoplay works but usually it turns off after 1 or 2 songs!!

Hello. For about a month or 2 videos on my mobile browser won't play with sound and sometimes they play without sound. The same situation I have with Brave browser. I tried Vanadium and IronFox and it works fine there. I really don't know what's wrong and how to fix it.

Suddenly Firefox has randomly decided that it will no longer play any videos anywhere ever. I have changed absolutely nothing, videos just fail to play at all. Every solution that exists on the Internet has failed to solve the problem. And I do mean EVERY solution.

I can open the exact same video on Chrome and it plays immediately with no issues. The app is simply broken.

Very cool. I love it when software stops working due to no fault of my own and nothing I do fixes it. Glad I spent two hours on that.
