Firefox for Android Community Forum

I'm hitting a weird lag in Firefox on my Xiaomi 17 Ultra (HyperOS 3.1 / Android 16). When I tap a link, there's a massive "dead zone" where nothing happens for anywhere between 5 and 30 seconds. The browser doesn't freeze—I can still scroll the current page or open the menu—but the actual request for the new URL just sits there. After this delay, the page finally snaps and loads instantly.

It feels like a DNS handshake timeout or some weird socket hang.

Device Info:

   Device: Xiaomi 17 Ultra

   OS: HyperOS 3.1 (based on Android 16)

   Firefox version: [впишіть версію, наприклад, 124.0]

   Connection: Happens on both Wi-Fi and 5G.

What I've noticed:

   It’s intermittent but frequent.

   Already tried toggling "DNS over HTTPS" (DoH) in settings, but the hang persists.

   Chrome doesn't seem to have this specific delay on the same device.

   Battery optimization for Firefox is set to "No restrictions" in HyperOS settings.

Is there a known issue with the networking stack on Android 16 or specific about:config tweaks for HyperOS to stop the system from throttling background requests? Any logs I should pull from about:networking to help debug this?

I've noticed that on using the app that it stalls. I have to toggle aeroplane mode to check to kickstart it back to life.

I can confirm it's not a phone or internet issue as I can switch out to chrome or share the stalling page to Chrome and it works immediately. This happens on different pages so it's not a page specific issue. I've even noticed it hanging on switching to a different app and then back, where the page suddenly stops functioning or loading.

I hate using chrome, I'd prefer to keep using Firefox, but I can't stand these constant pauses.

My device is a Xiaomi 15, I'm using the latest Firefox. I'm using the latest Android version. My Firefox app has only 1 extension installed ublock origin.

I installed Mozilla Firefox on my phone, but I cannot log in or create a new account. When I try to sign up or log in, it does not work properly. Please help me fix this issue.

Firefox hat am Donnerstag auf meinem Windows 11 - Laptop ungefragt ein Update veranstaltet und sich neu gestartet. Wie komme ich jetzt an die Inhalte der vorher offenen Tabs? Bei Edge konnte man "alle wiederherstellen" anklicken, hier habe ich sowas nicht gefunden, Chronik ist leer.

Firefox for Android used to have a setting that allowed users to control how long after private browsing is inactive, do all open private tabs close automatically. It used to provide options like 4 hours, 8 hours, never. It was present until a few months ago. My private tabs close automatically now in somewhat random fashion - sometimes minutes after navigating to another app. I also have enough Ram for such a problem not to occur. Can I still control this setting or does it have to be a feature request?

I love the browser and use it daily with Android phone and Linux laptop.

Concerning the new Android version, it is great. But please, bring back the select all tabs function. I like to save and backup my tabs by sharing them externally, and selecting them one by one is a very slow process.

Appreciate!

Hello, I am having trouble logging in to my Firefox account on my Android phone. Every time I try to log in, it shows an error and does not allow me to access my account.

I have tried entering the correct email and password, but it still does not work. My internet connection is working fine.

Please help me fix this issue. Thank you.

Hi, I am experiencing the following issues: Windows PC: When attempting to log in, I get a message stating, "Your account has been locked." Android App/Site: The page takes approximately 20 seconds to start loading. My phone is Xiaomi 14T Pro. Could you please look into this? Thank you.
