I-Firefox ye-Android Community Forum

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.

Naturally, I am not sure, which topik summarise my problem the best, so, I ask the question here. I found out that Mozilla browser takes a lot of memory in my smartphone (like no one app else). Cleaning up the cache didn't help much, because the most part of memory is taken by the "user data". Please tell me what exactly is it, what parts it consists of and how to clean it avoiding the ability to remove anything important. Thank you for the fast answering and for operativity Korwin

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.

Firefox on my wife's phone keeps randomly opening. How do I figure out what's causing this. First we noticed it happened when she plugs in an auxgzilery battery pack but then it's randomly opening anytime. What should I try to fix this. I thought I would remove and reinstall Firefox but I just figured the settings would remain as they are.

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.

If i search a topic, then search another topic, find a relevant page, then scroll back, it scrolls back to the original search topic and not what I last searched, then I have to type it again.

Hi, Being that OLED and AMOLED screens have become more frequent in recent years (and seem to be coming to stay) I am perplexed by the seeming impossibility of finding a way to make Firefox more friendly towards these devices.

I would like to use Firefox with a true black theme on its UI that would waste less battery and go easier on my screen's long-time durability. However, not only do I find that there is no option to do this in-built on the app, there isn't even support for external add-ons or thèmes that could get the job done!

There really shouldn't be any reason why, even if the Mozilla team are unwilling to code the option into the default settings, it couldn't be done through a user-made theme.

Instead, the solutions I've come across seem to span from third-party apps that require rooting the device to modifications made directly by decompiling the APK!

I know this was more of a complaint than a request, but heavy battery usage is a *valid* reason not to use something like a browser, which is likely to accrue several hours of use each charge cycle.

This *is* something Mozilla should care about.

TLDR;

Please point me to a way of making the Firefox UI AMOLED-black that does not require me to mess with the internals of an APK or void my phone's guarantee.

Sorry for the essay.

Pls help me my Firefox is now not working.pls adjustable and I will maintain your term and condition.Heylink.me not working if how to want.preview not show and adjust.pls help me

Every time I have a slow download speed that causes failure after interruption, I have to open the system's own browser, but the system's built-in browser is dozens of times the download speed, and there has never been a failure. The web page opening speed I have tested with the same search engine Bing search shows that the system only takes 3 seconds. Although the mobile version of Firefox also opens in seconds, it takes six seconds. I like Firefox very much, but it would be better if the mobile version could be improved.

On my Samsung Galaxy s6 when I try to add to the home screen and then choose the option to tap and hold and drag to the screen, it just closes the app it is nothing. It doesn't work. The text options from the pop-up do work but the main graphic where it's trying to get you to drag and drop it does not work.

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)!
