Firefox for Android Support 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.

Noticed my phone having terrible battery life, from battery usage you can see that Firefox is highly likely one of the main culprits. I have observed the same over a few days on the last two Firefox builds. It seems that it's not respecting the "Restricted" battery usage in Android (or Android is not restricting it, I have no idea), but you can see today's battery usage linked here: https://photos.app.goo.gl/pMByjqq6Q5GigcQu8

After I want to multitask on my phone and switch between the browser and other app. The page becomes blank and refresh button doesn't work.

I need to open a new card to continue using the website loosing all temporary changes made to it.

Redmi note 11 pro 5g with 6gb of ram

Issue was present for at least 6 months.

So I usually read long books that are only divided in chapters online, so no page numbers, using the reader mode in dark mode to make it nicer to read. The problem is that it does not save where I stopped on the page last time while reading like firefox used to as far as I remember. This makes things annoying as I need to remember and find where I stopped reading. Again, long browser pages with no page numbers to remember. I don't even close the pages on my phone and it happens both when I close the browser or just minimize it. I remember that it used to save it without problems. Is this a bug or just a removed feature? Hopefully someone here can help as I didn't find anything helpful via google. If there are more details neededI will add them on request.

So I have installed Firefox on my Galaxy S20 Plus running Android 12. All permissions are granted and everything is working except the camera. When testing it with https://webcammictest.com/ it ask for permission to use the camera and mic. I of cause allow the use and afterwards it says: The device is not found.

I have tested the mic alone and it is working. The test site is also working in Chrome, Edge, Vivaldi and Brave. So chromium browser do not have any issue with the camera or mic. I have also tried other tests sites with the same result.

I first noticed it when I had to call my doctor which sent a link to a site with camera feedback on. I was surprised and stressed about it wasn't working. Having a doctor waiting and a sick child, while installing Chrome to get it working, was not a fun experience.

Device: Samsung Galaxy S9/Android 10 Build number: Firefox v 99.1.1 Problem: Using Firefox as default browser, the user is failed to get redirected from webview back to app. SDK Version:

Amplify Android v1.29.0

Code used:

The onSuccess Action of Amplify.Auth.signOut is finishing but the webpage “dismiss” is not being triggered

Function call (image)

Has this issue been seen elsewhere? Is there any configuration that needs to be set to allow callback/redirects?

Firefox crashes almost every time I download something. It's all, I don't have any other info or a clue what to do I tried to add some info about that crash, but there is nothing in crash reports. It's like info about it wasn't send but I've done it right now

Fixing a crashed message/clumsy or delayed response to searched topics will surely provide confidence in using your app. So please act on this to be on top as you have been the leading app for years.

Thanks.

i had open a web page for some reasons. but the website asks to enable flash for load flash content or they prefer to download a browser. so what i do i dont want other browser. i need all features in firefox so pls solve this

Following question asked by petitechisa 7/31/21, 3:24 PM answered but not solved, by jscher2000 - Support Volunteer, then archived.

"Don't like PWA, please bring back 'add to homescreen' bookmarking/shortcut option."

I have the exact same problem as the poster, but only in last month or so. "Shortcut" doesn't open in normal browser (what's a PWA?) and page doesn't have a menu/URL bar, so useless. Normal app either gives "Add to Home Screen" or "Install" option, but both result in PWA (I guess), not a shortcut which opens in app. i. e. menu option irrelevant. Not happy (Just been reading a GitHub stream on the subject - deliberate Mozilla choice! Nobody likes PWA, get rid!!!)

Hi. I have identical problem like this post:

https://support.mozilla.org/en-US/questions/1313779#question-reply

Hello,

I’m encountering the exact same issue as here: https://support.mozilla.org/en-US/questions/1285325

The topic was archived and marked as solved. For me it clearly isn’t. Am I the only one?

Thanks.

I’m using Firefox Daylight 100.1.1.

Cannot remove pop up nag screen: "Useful modifications for easy turning and genuine"

Any time I touch my Samsung screen (without even passing security fingerprint) a Firefox message pops up

Cannot take screenshot of problem (pop up ms from Amazon via Firefox) . . as soon as I pick up the phone or attempt any action whatsoever, the message box disappears. And since I have a fingerprint access option on, the moment my finger touches the screen for full access there is no record of the message for screen capture. Also, if I do nothing, the screen goes black (normal, with time/date etc visible) within a few seconds after the message appears . . though it is waiting for me to touch the screen at which time it reappears again for a few seconds. So it is pick up the phone . . trigger motion detection . . message box appears . . wait a couple of seconds . . black screen . . touch or pick up the phone . . message box . . black screen etc. I can of course do the fingerprint scan and have full phone features, but the preliminary nag "box message" all the time bugs the hell out of me. In the text of my "complaint" I quoted what the message says, it is not from Firefox but does have a tiny Firefox logo upper left. The small rectangular window also has a left/right "full return" arrow (grayed out each one) with a black "pause" button in between the two arrows, and it is not grayed out. However nothing happens if I touch it. In very small print under the main text (first few words of my Amazon review) is a link to the Amazon page where I posted a review of a product. The message itself that I refer to is NOT from Firefox, but is comprised of the first few words of my review headline (not all of it but most) on the Amazon product comment review page. So even though the "content" of the unwanted message is from Amazon, the Firefox logo nevertheless appears (very tiny) in the upper left of the rectangular window, so it appears to be a composite error interaction between Firefox and Amazon. How to tell Firefox to stop posting it? Or how to tell Amazon that their software is somehow involved? I haven't a clue . . ! This is a re-written complaint . . the original one resulted in an email request from "Seburo" who asked for a screenshot, but did not provide a return email address that functioned. So I am posting here a second time, thanks.
