Firefox for Android Support Forum

Using Firefox mobile for android and GBoard.

I've selected Firefox as my auto fill service.

A few official apps (at least one banking app, for example) that I've downloaded from the play store that report the following after I unlock and select the correct password:

"Firefox could not verify the authenticity of the application. Do you want to proceed with autofilling the selected credentials."

I can't seem to find any other report of this error so I'm curious what's going on.

When I click on the scan feature next to the FireFox's search box, FireFox only shows a black screen. Same issue exists when I try to sign in to my FireFox account using the QR code scanner option. My camera outside FireFox works fine.

I just lost several hundred tabs on Firefox mobile right after it updated itself. The most recent tabs show only ten of those tabs, which were all opened and closed today and aren't part of what I need to restore.

How do I get my tabs back? I've seen no 'restore previous session' option. My laptop only shows the few I have open now. What do I do to restore them?

Firefox mobile android version 125.3.0 (Build #2016017559), 9f29904153+ GV: 125.0.3-20240425211020 AS: 125.0.1 On a samsung galaxy note 20 ultra 5g.

It is impossible to trigger a doubleclick or from some tests, extremelly difficult to do. I calculated that in order to trigger a doubleclick, the 2 clicks needs to be somewhat no more than 0.08 seconds aparts. :That's wrog and inaccessible, the value should be between 0.4 and 0.8, NOT 0.08.

Firefox mobile should support doubleclick: https://developer.mozilla.org/en-US/docs/Web/API/Element/dblclick_event

About:config is not available and my phone on vpn at ipleak.net says webrtc detection shows 10.41.0.162 IANA private or special address and 2001:db8:123:10a0 IANA private or special address.

Aren't they internal LAN ip's? How can they be seen even without a VPN when I have NAT.

Hey, I would like to SET MY SD CARD AS DEFAULT DOWNLOADS LOCATION on my ANDROID PHONE( so that my downloads aren't saved on my phone's internal storage). Please help me with a step by step procedure. Thank you!

Hi, this issue has been present for a long time for me, and with many versions of Firefox Nightly for Android.

I'm always using the latest nightly for browsing Youtube only, with a set of specific settings and addons (since we can't use profiles on Android yet)

My problem is I've configured the Homepage to never show anything but a few URLs I chose to pin, you can see my settings and my homepage in the screenshots attached.

Despite the "Recently visited" setting being disabled, sometimes, but not everytime, the last pages I visited are added to the Homepage, after the pinned sites. I have no idea what triggers it or not, if I'm doing something wrong or if it's a bug.

Thanks for your help !

Firefox for Android does not follow system theme changes i.e. dark to light.

Discovered on Samsung Galaxy A22, Android 14 and Firefox 124.2.0

Steps to reproduce:

1. Configure Android to automatically switch themes. For Samsung Galaxy this is Settings - Dark Mode Settings - Turn on as scheduled
2. Wait until Android toggles theme from dark to light.
3. Notice Firefox has a black border.
4. Go into Application info for Firefox and force stop, then reopen
5. Now notice it doesn't.

This is a reopen of this archived issue: 1421453

For some reason, when I click email links on my new Android, they open in non-private mode, and I have to clear the history when I leave those sites.

Please provide instructions for automatically opening email links in private mode.

Thanks!

I have noticed that for the past several months Firefox for Android begins draining my battery after being installed for around 2 weeks. I'm using a Google Pixel 7 (128GB) running Android 14 (AP1A.240405.002) in the UK.

At first, I thought this was being caused by an add-on, so I reinstalled without add-ons and slowly started enabling them day by day until I caught the culprit (which if I recall correctly was Dark Reader). However, even after I disabled the Dark Reader add-on the problem persisted, and no matter how many times I uninstalled and reinstalled the app, the background battery drain issues would eventually come back after ~2 weeks of being installed.

At present I have only three add-ons enabled in the browser: ClearURLs, Decentraleyes, and uBlock Origin. I have used these add-ons in the browser for years without any issues.

It's now got the point where I am so fed up with this issue and the need to constantly reinstall that I will be using a different browser for the time being until this is fixed. I really want to use Firefox as I use it on all my other devices, but this is too much of an issue for me to ignore.

I've included screenshots of my phone's battery consumption whilst I'm asleep, and whilst I'm watching Youtube on my TV over lunch. Both of these are times I'm not using Firefox.

Any help on this issue would be greatly appreciated.

I'm not sure why, sometimes the status bar clock and stuff do hide, but I just can't seem to figure out how to get them to hide every time, and they usually don't. I've already tried disabling picture in picture for the app but that isn't noticeably helping. Full screen video is supposed to hide those, right? What are the reasons it wouldn't?

Hi Guys!

Can high resources eatin' (maybe graphics, IDK) Ads, for Me in the Webside embedded and (sometimes) with 'movie' like movement decorated, automatically get blocked?

My phone runs slow, 'even' with just 1 Tab open and only Firefox Mobile App on the phone active.

Sorry, I can't see the field I type in currently, maybe I writ a bad layout right now, but content matters XD.

"Hi there! I've been experiencing some difficulties with the Mozilla Firefox mobile browser on my Android device. Whenever I try to open certain websites, the browser crashes unexpectedly. I've tried clearing the cache and reinstalling the app, but the issue persists. Could you please provide some guidance on how to troubleshoot this issue or any possible fixes? Thanks in advance for your help!"

I have firefox for android, and I have ublock origin, which is great.

However, firefox seems to refresh constantly- even if I minimize it than return instantly- it automatically goes into a refresh mode, it refreshes randomly while scrolling- I wish I coudl completely turn this "feature" off across all browsers.

I cannot state how many times I have lost VITAL data from this annoying random refreshing.

It should be an option to completely disable refreshing of ANY kind, rather than forcing it down our throats, and losing time, and data. If I want to see new content I will refresh it myself/ re enable the option. I was hoping this ridiculous "feature" would be phased out when humanity pulled its head out, but apparently- it's gotten even worse, now.
