Firefox for Android Community Forum

I'm having a problem with playing videos on websites. When I click the expand to full screen button about half the time the full screen video comes up for half a second and then the window shrinks down to a small square on the bottom right-hand corner of my screen. Sort of like when the youtube app minimizes a video. This window is unclickable and also everything at or below it in android is unclickable while it's there. If I click the window button on android and swipe the firefox app up to close it and restart it, Firefox doesn't even close and I can still hear sound from the video. I have to select on the Firefox app again which will restore the full window and then click the full screen button one more time and it will work. This issue is happening on every website I play video on on the Firefox app and it is extremely irritating. I'm about ready to switch to another app if this can't be solved, but Firefox is the only browser that allows ublock origin so I don't want to do that. Can anyone help?

Video playback initially works, until suddenly it doesn't; no new videos will work, and videos that previously played in the same browsing session will stop working. Easy to reproduce on Reddit by browsing any video-heavy subreddit. Leaving a broken video in a tab seems to infect the rest of the browser across websites; if a broken video from site A is open in another tab, videos on site B won't play.

Sometimes quitting and restarting Firefox is enough to temporarily get video playback working again; sometimes I have to manually clear the browser cache; at least once I've had to reboot my phone.

Firefox is using a large amount of battery while idle. You can see my app runs open a lot of the day, but not in use much. It has drained 20 percent of one days battery, and I am watching YouTube videos on another app (Grayjay btw check it out!) and it has used far less battery. If I set Firefox into a sleeping state, the app still drains a lot of battery. When in deep sleep,it stops draining as much power, but then Android keeps auto pushing their own browser to be my primary browser. I'm not sure what to do in this case, as it's too much of a hassle to have links not auto open in Firefox when in deep sleep. This excessive battery drain doesn't make sense, and I was wondering if there was any fix for this. Thanks for taking the time.

The browser itself works in 120 Hz, but if you open any page, the phone switches to 60 hz. However, if you open, for example, the keyboard, 120 Hz is enabled again. This makes using Firefox uncomfortable. I have attached screenshots that show my problem.

When I try to enter a password for any website after a few updates ago, I don't get the option to enter my password that's saved in my password list into the fields anymore. I have to manually search, copy, and paste the information in. The app will then ask me if I want to update or modify the login information that is unchanged from what should already be in my browser.

Regardless of whether I say yes or no, the password remains unselectable when I go back to that website, and when I manually enter the information, it again asks me if I want to update the login information.

This hang is not consistent. I have been switching back and forth to get details for this thread with no issue. But very frequently when I have switched away from Firefox to another app and then returned to Firefox the app has completely frozen. I can see everything clearly but can do nothing at all (neither the web page or Firefox). I haven't yet identified a pattern.

132.0.2 has Relay and CashRewards installed. 133.0b8 is vanilla.

I'm using gesture controls on HyperOS to switch apps.

No issues with any other apps.

Is this where I report such things?

I'm trying to enable javascript on my firefox android mobile device. But when I type the about:config instruction in the address bar, the response firefox gives me is that it can't find that page. Why can't firefox find this page? I need to enable javascript in order to use my trusted Speechify text-to-speech app.

On the latest Firefox Nightly builds (I use Nightly for extensions), holding the back button in the Android navigation bar no longer brings up previous pages, like it does when holding the back button in the three dot menu. Is there a config option to bring this back?

Hi, Most of the time when I search, the engine automatically used is Bing and not Google. This is despite setting Google as default.

Is this an annoying bug? Or am I doing something wrong?

Thanks

The upload photo button does nothing... on this page, on Reddit, Facebook too. I've tried clearing cache. I'm on latest android and firefox 124.2.0. I have standard security enabled and permission is set to "Ask" for camera and storage. How do I make this work again?

While browsing www.youtube.com, the site is not running smoothly. When I'm scrolling in the YouTube homepage, it's like cutting in the middle. On the other hand when watching YouTube shorts, when scrolling to a new video, it's like jumping and then loading, which seems extremely inconvenient. Overall the YouTube site is not working properly in Firefox mobile (Android 13). Note: I have tried the cookie delete option. Still persistent.

Hello, I've been having issues with the Firefox app on my Android ever since the most recent update on 4th of July. Whenever I tap the "tabs" button, the tabs viewer opens as always, but if I try to scroll and browse the tab, or if I try to close any of the visible tabs, the whole app crashes. Because of that, I can only switch between tabs by swiping, but it can be annoying if you're used to using many tabs like myself. I have cleared my cache multiple times and it didn't help. I am not too tech-savvy but is there any way to fix it? Thank you!

I recently downloaded Firefox on my Android device. It's been fine. However today, there was an issue. I have the settings set on my phone so bookmarks appear on the homepage. However, today, for some reason, the bookmark on the homepage was glitched. I'm not sure why, but I figured I just had to reset it. So I go rid of the bookmark on the homepage, and redid the bookmark. It was working again, but now, the bookmark isn't appearing on the homepage anymore. It's just a blank homepage, even though my settings are still the same. I've turned the settings on and off, reset fire fox, cleared cache, and the bookmark still isn't showing up. Pleas help me.

for a recent update or two, when I am watching videos in fullscreen, at least like me, for example, when I entered fullscreen, the video should play horizontally, but after merely half a minute, the screen orientation goes back to vertical mode automatically, which is not happening when I began to use Firefox android months ago. Watching same website on different browsers, only Firefox goes wrong, so I think this should be Firefox's bug.

For the past few months, videos on YouTube haven't been playing properly. They load just fine and there's no issues with the auto, but once the video starts playing it will sometimes be zoomed into the top left corner, making it impossible to properly see what's going on.

This happens with music videos too, both official and lyrical. It will be zoomed in close to the top left corner and just barely catches what's going on in the video. Sometimes, video do play like they're supposed to, but for the most part, they'll be zoomed in as soon as I hit play.

The site (which I have used before on this phone) now tells me I must have Javascript enabled. I have looked through SUPPORT and I see 44 other inquiries on this topic but no answers. HELP!

Hi. For the past few months I have been unable to play any samples from the Audible website in Firefox on my android phone. When I click the word "Sample" Audible opens up a new tab with their Web player and I always get an error message that is just a rectangular box with an exclamation mark inside a triangle on the left side of the box. (Screenshot attached.) There are no words inside the box and the only option is to close the tab. Since there is no actual message I'm not sure what the problem is.

Here's a link to the page visible in the screenshot: https://www.audible.co.uk/webplayer?asin=1445081911&contentDeliveryType=Unknown&isSample=true&ref_=a_pd_jpp_cloudplayer_1445081911&overrideLph=false&initialCPLaunch=true

Playing samples used to work fine when you could play them within their web page before Audible changed its system. I seem to be able to play samples on Audible's Web player in Chrome, but would prefer to keep Firefox as my default browser. I have tried deleting all history, cookies and cache; closing and reopening Firefox; turning phone off and starting again after an hour. I've also tried enabling autoplay, but that made no difference. I was thinking that the issue may be with my other settings within Firefox, but I can't tell. Any help you can provide would be great. Let me know if you need more info. Thank you!

(I'm in the UK. I don't know if that makes a difference, but I don't see a UK specific forum. Thanks.)
