Firefox for Android Community Forum

Hello,

I'm facing a severe battery drain issue that occurs with all of the current Firefox versions for Android (Stable, Beta, Nightly). I have noticed that the problem mainly arises when I have played any type of video through the browser, such as a YouTube video or any auto-playing html video through a website. And I don't mean that the battery drain occurs WHILE I have the browser open, I mean in the background, after I have exited Firefox. I have also installed GSAM battery monitor with the necessary ADB battery stats permission given, and it seems that the "Video On" wakelock is always on with Firefox. It's like that the thread that plays the video has not stopped, even if I have force closed Firefox, and killed the video tab. For example, I'm attaching two screenshots from the battery monitor, where I have previously opened Firefox and played a video for like 15 seconds (see the "Audion On"), then immediately closed all the tabs and force closed the application. As you can see, the "Video On" has not stopped, like the "Audio On" wakelock, and continues to count (35 minutes). This may go on forever, such as if I leave the phone at night, I'll wake up the next day with Firefox video wakelock displaying something like 15 hours of playback (something that of course, is not true). The only way to stop the drain, is to restart the phone and not open Firefox.

Though, the issue may not even be related with video playback. I have read in the forums (like here: https://support.mozilla.org/en-US/questions/1432706) that other people are facing this issue as well, and worked around it by not using Firefox as the default browser. I have not tried it but, even if it works, this is not at all convenient. Other posts on reddit that verify the same issue I am having: https://www.reddit.com/r/pixel_phones/comments/18xh7w3/why_is_firefox_using_all_this_battery_i_havent/ https://www.reddit.com/r/zenfone/comments/18zlow0/since_android_14_video_seems_to_be_the_top/ https://www.reddit.com/r/firefox/comments/174d13d/firefox_excessive_battery_usage_on_android/

I do not wish to switch to chromium based browsers. Please take a look at the issue and let me know. Thanks a lot.

Firefox has been a great browser on my new S22 however I have noticed recently that it has been dropping my battery percentage extremely fast, and I notice its lower almost every minute I check. This is confirmed in the battery settings menu where it shows an abnormally high amount of usage, when I mainly use Firefox for general browsing and close background tabs.

Hello, Long time user and lover. Never had any problems with your great browser. This past week, on my phone, Firefox has been flagged "high battery background usage" and is continuously trying to put app to deep sleep. What has happened? How do I stop this? Any help or suggestions would greatly be appreciated Thanks Scott

I used the Firefox mobile app for a while now and I noticed a high battery usage from it. If 10% of battery gets drained during the night, at least 75% of that is used by Firefox (according to the battery stats of my Pixel 6)

Is it possible to slow down the background sync or maybe dont sync at all during the night if the phone is locked?

Thanks.

I have a "Samsung Galaxy S21 FE 5G". It's One UI has a pop-up view that shows app in a floating window. However when I enable pop-up view for Firefox, it becomes an unusable black window. when I return it to normal view it still remains in black and the only way to make it usable is to close the app and then reopen it.

As far as I know This was happening in Andriod 12 and OneUI 5.0 and in Andriod 13 OneUi 5.1.

Hi,

I've been using firefox for 20 years and never experienced problems with webpage display until I started using it on my new phone samsung s23 ultra.

More often some webpages will not size correctly with my screen and is cut off so I have to switch to chrome.

For example, only 80% of this webpage is displayed. https://www.unsw.edu.au/newsroom/news/2024/04/pfas-forever-chemicals-above-drinking-water-guidelines-in-global-source-water

Is this a bug?

Thanks.

Usually happens with youtube embed links, not sure if it happens with other(non-embed/other website) links, but it will ask me to open with app or in browser, and can't be cancelled with back button, only home button. when I press home button and reopen the app the embed will disappear in the page

The browser stopped working since last week. Before when i opened the browser, i can see it loading. But nowadays, the loading is gone and only black screen is left. I cannot even access add-on. Its just loading

Websites are not loading, search is not working. The app is not working at all. Tried closing and reopening FF, cleared cache, rebooting phone and few other settings but nothing helped. Tried googling around the problem and most of the users are also facing same issue. It might be fixed by reinstalling the app but I CANNOT do that because my site data is important and I don't see any way to backup site data to my PC. Please help with the issue without losing FF app data.

Despite updating to the latest Firefox version (127.0) and performing a reset, I continue to face high CPU usage issues. The battery monitor reports extensive CPU consumption for minimal use, even when only a single tab is open. This problem is not exclusive to the main Firefox app; it persists across other Firefox-based browsers as well.

Device: Xiaomi (HyperOS - Android 14) Issue: High CPU usage across multiple Firefox versions Troubleshooting Done: App reset, tried alternative Firefox-based browsers

I urge the development team to investigate this recurring issue, as it significantly affects the performance and battery life of mobile devices. Your prompt attention to this matter would be greatly appreciated by all users experiencing similar problems.

HELP! My mobile data usage spiked as of June 20th and has continued at unprecedented levels almost every day since. My historic daily usage for the past many years has been around 4 MB and is now 95MB. and busting through my 2GB/month limit. This is ALL due to Firefox! What happened? Something strange happened on June 19th, when my mobile date usage recorded three separate usage figures instead of the single usage figure for all days previously. June 19th showed 2 usage figures and June 30th showed 3.

When I click on a web push notification in Firefox on Android, the link in the notification does not open. If no page is previously open in the browser, a blank tab appears. If another page is open, that page is displayed.

Hi,

Basically my self hosted jellyfin instance throws an error:

Corrupted Content Error

The page you are trying to view cannot be shown because an error in the data transmission was detected.

   Please contact the web site owners to inform them of this problem.

But on chrome it is working as expected. Any way i can check for errors in the android app?

I'm using my android tablet to access the Microsoft website. When I click on the link to the desired page, the page flashes for a second and then goes blank. What's wrong, and how do I fix it?
