Is there a way to force "dark mode" for websites on mobile WITHOUT using an extension like Dark Reader?

I am comparing this to coming from Brave, where I am using their "experimental" Night Mode settings (which works great). For the desktop browser, I've gone to Manage Colors and swapped text/background white/black to make most websites appear as if they have a dark mode, but that option doesn't seem to exist on mobile.

I've attached 4 images that show the differences across the two browsers on mobile. Even Google's own Dark Theme doesn't seem accessible through whatever method FireFox uses, so I can't even use that dark theme without an extension at the moment.

If this is not currently possible, I'm hoping it's planned for future implementation. I can't suggest it either since the feature suggestion page appears to be down at the moment (being reworked?).

When I play YouTube videos the audio functions but I get a black screen. Tried it with add ons disabled still have problem. Videos play in other android browsers (opera and chrome) and in YouTube app but not in fx.

Cleared cache, cookies, restarted phone, checked for system updates. Not having problem with non YouTube videos.

Using fx version 110.1.0 (Build #2015936097).

I am using the video background fix addon but whenever i minimize firefox, it will play the current video untill the end and will not autoplay the next one. I have to bring forefox to the screen again and then it starts the video.

On my much older Android device, i am using the same setup and have no problem with autoplaying the next video, even when firefox is minimized. Any suggestions?

YouTube videos on Firefox Android Stable, Beta, and Nighty, experience significant frame drops when viewing "Stats" both on AVC1 and VP9, and on all resolutions. I checked about:config in both Beta and Nightly and HW acceleration was enabled. This was true for a FRESH install as well. I tried this on other devices and the problem persists. Mull, which is a fork of Fennec, plays the same videos without any problems. Other browsers are also fine.

Tested on Samsung S20 One UI 5.1 (Android 13). Tested on Samsung A13 One UI 5.0 (Android 13). Tested Sony Xperia XZ2 Compact (Android 10). Tested on Sony Xperia XZ1 (Android 9).

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?

Hi,

Xiaomi 12, when reading a webpage in Firefox scrolling with the finger every 3-4 times the page does not scroll. Instead the address bar at the bottom pops. Lifting the finger and scrolling again makes the page scroll. This problems repeats.

Help would be appreciated because it is very annoying

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.

Im using Firefox android on my new pixel 7. I found that the 'add to home screen' option is not available on the ... List. I searched for solution. Someone say click on Install option. But there's no install option either.

The add to home screen is available on my old moto phone

Does anyone have this same issue and have a solution how to fix this? I very much appreciate all your help!

Hi everyone. I hope you're doing well.

So, I've been thinking about downloading the Firefox browser for Android but I am worried.

I saw this among the app permissions on Google Play Store: "download files without notification". And I am worried.

And I need to know:

- What files does Firefox download without notification?

- Why does Firefox download files without notification?

- When does Firefox download files without notification?

- Why and how should I trust an app to the have the ability to download anything it desires at anytime it desires without my knowledge or my choice to accept or decline?

Could you please help me and tell how this app is safe?

Thanks. Have a good day!

In the recent update, there is a new feature which allowed people to view pdf directly in the browser rather than downloading it. Ever since this was implemented, I am not able to download any pdf, instead it keeps opening up the pdf in another tab which is not what I'm trying to do. Is there a way to fix this?

I am using Firefox nightly on Android. About two weeks ago I noticed that my toolbar got moved to the bottom after some update, while address bar is still at the top. I tried looking for it in settings but couldn't find anything about toolbar, that's weird since I was able to customize it a few years ago when I installed Firefox for the first time. So I looked it up on the internet and they say that it's in Settings/Customize/Toolbar, but in my browser settings instead of Toolbar there is Address bar settings. Has toolbar's settings been moved somewhere else? It looks like in previous versions it was under Customize section.

The second attached image is from this video:

Happening on all platforms that I checked, from Youtube to Kick and several others. Basically the video just keeps on trying to load forever but never does, same behavior on all sites. Chrome is loading videos fine, other devices with Firefox are also fine.

Been using Firefox on Android for years with no problems. Wondering if this is my problem and I need to troubleshoot or if others are having the same issue, in which case I can just wait for Mozilla to roll up some update fixing it. All I did up to now is disable add-ons but the problem persists. I'll do a fresh install if I really have to but I'll wait for a response here first to make sure. Cheers.

Hello all,

I had been using firefox as the standard browser for years, but since the DNS-over-HTTPS feature I have had trouble with protecting my family on the web via DNS filtering. Currently the only solution that has worked is to use a different browser (the Spin browser, for whoever is interested). I have Firefox blocked using the Android family link feature (and they can't install new apps without permission). Personally, I would love to move everyone back to Firefox, but I can't find a way to do it safely. Is there a way to effectively disable DNS-over-HTTPS such that it can't be changed (kids are pretty quick at figuring out that they can just go to the settings and figuring out that they can turn the feautre back on). A parental control feature would be ideal, so I can just set the DNS-over-HTTPS to use the family DNS filter in a way they can't turn it off. Does anyone have an helpful solution, or is Firefox dead for family protection?

Respectfully, Andrew

Hello,

I'm new to using a smart phone and have downloaded Firefox Mobile onto my Android phone. It works great when searching for a website but I have one that I already know and would like to go directly to it. Unfortunately every time I enter the URL I get a search for the website, not the website itself.

What am I doing wrong?

BTW, I'm not using my phone to post this question but rather my laptop (which I find easier to use). My phone is a Moto G Power (2020) using Android 11 and FF 110.0.1

Thanks, Andre'a

Hello,

Firefox 120 is freezing my Android 11 phone when I start typing on the search bar (weirdly it start to happens when a space is inserted). It freezes so hard that pretty much it takes 30-min to 1 hour for the phone to restart or the battery to drain.

Reverting to 119.1.1 solves the problem immediately.

My guess would be that maybe the search bar or the suggestion related code introduced something weird, as I do have a lot of bookmarks. Nevertheless, it's definitely a new issue (been using Firefox mobile since first day around 2010) and introduced in 120.0.

Since the phone is hard freezing, I can't even connect in ADB and try to see any message hinting at what's wrong. If there's a crash trace maybe some info could be dug there.

Thanks in advance for the help!

Firefox on my android phone times out on any webpage whenever I am not connected to a Wi-Fi. All webpages and IP addresses timeout with no response. Same issue occurs on Firefox Beta app and Firefox Nightly. All other applications work as expected with full internet access on mobile data. The same pages/addresses respond as expected on Chrome and the built-in browser.

Simply put, all Firefox apps have no internet connectivity on mobile data.

Solutions I've attempted with no success or change: Re-install Firefox. Logging out of Firefox Sync. Clear Firefox data and cache. Disabling tracking protection. Disabling HTTPS-only mode. No proxy settings are enabled. Confirmed Firefox application has mobile data network privileges. Disabling, re-enabling mobile data network privs. Installing Firefox Beta and Firefox Nightly; same issue.

Another possibly related issue: Firefox does not follow routes from a Cisco AnyConnect VPN on my phone. Opening pages/IP addresses routed through the VPN are rejected or timeout as if the VPN is not active at all. The same pages/addresses respond as expected on Chrome and the built-in browser. This occurs over Wi-Fi as well, of course nothing works on mobile data as described above.

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
