Just recently Firefox has gotten really slow to open. Sometimes it won't open at all. I tried uninstalling and reinstalling it which helped for about 2 tries. I thought it might be a problem with my phone but chrome loads instantly. Once it does open it's slow to go wherever I try to go and sometimes just quits and takes me back to the home screen.

So I have noticed it for a couple of years now, and still this issue isn't solved. I am attaching the screenshot. When my phone is in an idle state, the Firefox app is in the background and my screen is switched off. Then the Android device should go into doze mode and save battery, but that doesn't happen due to Firefox. There is an audio wake lock, and it doesn't let the phone go into doze mode. If I always try to close the tabs when I am leaving Firefox, then yeah, it gets solved, but that defeats the purpose of having a powerful smartphone.

Running Nightly (153.0a1 (Build #2016163271), a4d50ea7cb22bb9324cc8d62c6a03bfe902ea170, GV: 153.0a1-20260526143706, AS: 153.20260525050231, OS: Android 16) and Samsung reports the app is frequently crashing; additionally and randomly, websites won't load... No error message, they just seem to hang.

I'm more than willing to provide logs if someone walks through the collection process with me.

I just wanted to point out that the browser on Android has too many processes running in the background—I’ve never seen anything like it before, and it doesn’t seem normal to me. I’ll attach some screenshots of the processes on my phone.

Hello on my Samsung S24 synchronisation of email became very slow for a few days. I trier to réinstall TB but it did'nt change anything. Do you please have any idea where could be the bug and the way to fix it ?

Well, I just updated and still have the same problems. This browser is simply impossible to use; I can't even throw it away and forget about it: it can't load a single page without getting stuck halfway through, after which the app freezes and has to be interrupted, unloaded from memory, and only then (maybe) will the page load! It's been like this for six months now. It's probably time to ditch it completely!

My Samsung Galaxy S24 Ultra keeps reporting that "Firefox is using too much battery in the background. Put it in deep sleep to extend your battery life.". I have set background battery use to "restricted"and disabled background data. I don't want to put the app into setup sleep because then it will no longer be the default web browser.

If I'm on a website and let's say I'm reading an article and I'm midway, if I switch to another app momentarily for a few seconds (eg go to a messenger app to send a quick message) most of the time when I get back to Firefox it seems to reload the app and refreshes the page. This makes me lose my scroll position and progress. This doesn't happen on other browsers like Vivaldi,it feels like aggressive memory management. Please fix this if possible because I don't think it's my phone's issue , I have a Xiaomi 14 Ultra with 16gb of ram and Android 16 (latest hyper os 3.0.3)!

I have only 4GB RAM and that can be an additional factor that causes this issue. When I listen to Youtube Premium in the background (with video window hidden) and switch to Firefox, Youtube Android App is killed. Same thing happen with Youtube Music from time to time. For Youtube, I can workarund this issue by keeping video in Picture-in-Picture (PIP) mode.

I play games via android on PC using MuMu emulator, However the text becomesdistorted/cut off and little patches of colorful static patches appear when I scroll up or down. This is a problem on EVERY emulator I tried so far. This includes Memu and bluestacks as well as MuMu. They are ALL updated and I run the emulator using 8 core 16GB ram with DirectX and medium graphic settings. I tried low graphics and high and Max graphics all same issue. I tried using Vulkan and even the lowest graphic engine and SAME issue. This started happening after one of your updates but not sure which one because I just started using emulators again after many years of looking for emulator that does not bombard u with bloody Ad's..

Would appreciate it MUCH if you can fix this issue so I can use firefox to search for apk apps and games, I WILL NOT use anything that is based of Chrome aka Chromium (also a known in MANY verisons as a VERY dangerous and destructive malware/virus) and I also found a hidden remote access plugin on PC version too.

I been a devout Mozilla firefox user since firefox version was still in single digits, aka Ver 3.6 (example, I started at around Ver 5.x or 6.x hard to remember)..

Just installed TB for Android on Samsung S24 Fe. Works fine but am unable to exit the application other than forcing phone back to home screen. Have installed on a Samsung tablet and the back button seems to be working OK. Anyone know of any issues with this phone and TB?

Firefox runs in background even after menu quit option with clear all browser history (proper exit). Firefox heats my phone while using. I am using Android 13 phone.

I left a review and was asked to post this here so here goes. Firefox on android is currently the highest user of power on my Google Pixel 8 android phone. From the battery usage data (since last full charge) Firefox has used: Screen time: 2hrs 33mins Background: 5hrs 46mins Totalling 19% battery usage. Even though I turned OFF allow app to run in background!! Before I turned this off, the battery usage was similar. In comparison: WhatsApp -the next highest- is: Screen time: 1hr 42mins Background: 17hrs 52mins Totalling 14% battery usage. With allow app to run in background ON.

The only thing I can think of causing this is the annoying (in my opinion) way that Firefox does not close down all open tabs when I close the app (by hitting the square control button and hitting clear all open apps button) are they still keeping Firefox running in the background as they refresh?

PLEASE add a setting to close all tabs when closing the app. When I close Firefox on my PC and then open it again, I don't get my old tabs, so it must be possible to do on android.

Firefox stürzt seit einigen Wochen immer wieder ab.

Auch ist es sehr langsam, oder lädt die Seiten nicht.

Auch kann ich nichts schreiben, zwischendurch.

Es nervt!

Und ein neues Update gibt es nicht.

Wenn es so weiter läuft, muss ich einen anderen Browser nehmen, was ich gar nicht möchte, da ich Firefox, seit Anfang an benutze...
