Firefox for Android Community Forum

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.

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.

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?

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?

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!

When switching to another app from Firefox and then switching back to firefox, the webpage reloads. This is not a memory issue, I have enough RAM and it happens even if I only have 1 tab open. This is a major pain when I need to enter a 2FA code and need to swith apps to get the code. Or if I'm watching a YouTube video and get a call, the youtuve page reloads after the call has ended. Please suggest how to fix this.

It's so annoying that you ask for my password when I'm already logged in obviously. I'm on the same phone the same internet at the same address you should know by now it's me. And then nobody remembers the password even though they said they remembered it and I don't remember it. And it says if I reset my password I'm going to lose all the bookmarks and all of my logins. What the heck? Why isn't there always option just to login with my Google account? It does sometimes but not always.

I own a Samsung Fold 5 phone. I have set the outer display used when the phone is folded to 300dp. The inner unfolded width is set to 601dp.

Up until very recently, when I folded or unfolded my phone, websites would resize. Often switching between layouts made for phones and layouts made for tablets or desktops. This still happens in Chrome. But no longer does in Firefox. Instead the site has the same resolution in both modes, making the text too small to read when folded. This effectively makes Firefox unusable unless I unfold my phone. Please make Firefox respect the resolution I have set for each mode again so I can view websites at a width of 300px in folded mode like I used to.

Note I have the slider for "desktop site" turned off. When I try to turn it on, nothing happens. The slider doesn't activate and the resolution does not change. (But the page does reload.) This used to give me the option of 3 different resolutions for my screen, (300 folded, 601 unfolded, and something like 1024 in desktop mode.) I'm not sure if desktop mode is permanently turned on now, or if the phone is set to permanently use 601 width, but it is definitely not using the 300 width I used to get when folded. The desktop mode slider is to the left and will not change.

I opened site settings and turned off always request desktop site and nohing changed. I am still unable to get the 300 width site I need to be able to use Firefox on a folded phone.

My tabs are being refresh everytime after I left to switch to other tabs then come back. This constantly happening even when I did not open another app, just browsing between firefox tabs. Already play with battery setting in app info and change it to unrestricted and nothing changes. Can anyone help? btw I'm using galaxy tab s6

Recently firefox for android mobile stopped allowing me to take screenshots. I get the error msg in the subject line when pressing the volume down and screen sleep/wake button. Is there a setting I can change?

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?
