Firefox for Android Support Forum

Then I tried open any site in Firefox on Android I saw next error:

XML Parsing Error: no root element found Location: chrome://geckoview/content/geckoview.xhtml Line Number 1, Column 1:

^

I also attach screenshots with error and browser version

In previous version of Firefox (the one with regular tabbed browsing for normal and private browsing) if use https://api.whatsapp.com/send?phone=0919848012345, I used to get a button continue chat and clicking on it used to take me to WhatsApp directly. Not the button directing me to an WhatsApp page asks me install :(. Also selecting the URL used to give me WhatsApp app icon along with cut copy paste options, which also used to direct me to WhatsApp. Now that icon is missing. The same is working on chrome on the same mobile. Firefox version : 89.1.1 (Build #2015812947) AC: 75.0.22, 5204f4025 GV: 89.0-20210527174632 AS: 74.0.1

Attaching pics : 1. Firefox showing message that WhatsApp isn't installed 2.selecting URL doesn't show WhatsApp option 5. On Chrome, Clicking on chat button directs me to WhatsApp. 3,4. On different mobile with same version of Firefox, Selecting URL shows option to open and clicking on it gives option of whatsapp

I'm getting Secure Connection Failed error on every single website I try to visit. Including sites such as microsoft.com, duckduckgo.com, google.com, etc. (Strangely, mozilla.org works fine.) Try Again never works, and Advanced - Accept risk works sometimes, but not always and if I close Firefox app and re-open it's back to the error page. I can't believe this is a common problem, so there must be something about my phone that's causing this. Android 11. Happens whether or not WiFi is enabled. What could it be?

Websites are fine, but if I open up the address/search bar firefox instantly begins to lag and there is a serious (5 seconds or so) delay between typing and the text appearing.

I have tried disabling search features (search from history, search bookmarks), I have tried disabling add-ons, and I have tried clearing the app cache

Weirdly enough, this problem persists on Firefox Nightly, which I had never downloaded before just now.

Please help.

I got problem on my oneplus 8 pro. when go full screen on youtube subtitles doesnt show and video fits screen. I added two screenshot first one is from firefox and second from samsung browser(that's how it must be).

Since the last system update for my mobile phone all shortcuts to websites in Firefox have disappeared. Also I can't add new shortcuts. Add to home in other browsers like Vivaldi is working fine.

I have a Samsung Galaxy Tab 4 SM-T530 with Android 5.0.2. I recently downloaded both Firefox and Firefox Focus but I haven´t been able to use neither of them: at first they just crashed, but now the tablet restarts a few seconds after opening and trying to browse anything. Every other app seems to work just fine.

I reinstalled it a few times. I've been able to view "about:crashes" and there were no crashes. What else can I do?

I don't want to use Chrome :( Please help!

Hi there I have used Firefox on my android phone for the longest time, and never had an issue. A couple of days ago it crashed immediately on trying to open it. I repeated trying to open it across the course of the day - but continued crashing. I deleted it, and have set to use Chrome. I reinstalled Firefox - same issue. I am not techy-techy (!) but would like to have Firefox back on my phone as all my passwords are there. Any help appreciated Thank you :)

after updating to Firefox android 97.1.0 I face this error. while playing youtube video in full screen, bottom navigation bar is visible making it half baked full screen mode. later found it is same in other video playing websites too... Firefox goes fullscreen mode automatically while navigating in youtube and quite buggy in navigation bar.

I had no issues with previous version. I shouldn't have updated. I received only bugs in this update and no improvements. using Firefox in LG G8X running Android 11.

please fix this bug or share any possible solution available.

Hi dear people,

Unknown phone, "Nexus 5" is log in -ed and recognized as "mine" but is actually Redmi Xiaomi model.

See attached pictures please. I removed the device "Nexus 5" and signed out from Google and Firefox, but didn't help it keeps coming back and showing up also as "Firefox Mobile 97, Android 11"

I had an update today on my Samsung tablet through the Google Play store and now suddenly I can't use my Yahoo email. It was working fine this morning. Every time when I do get it to come up and if I click on anything it goes blank. No issue on my Android phone nor on desktop on my PC. I really don't want to use the Yahoo app because I did that years ago and did not like it. I did try clearing cache, turning off the tablet and turning it back on and tried to use another tab after x-ing out of the one I was using. Anyone have any ideas about what I can do to get my Yahoo email page to come back? Thank you, Betty J.

Ever since the Firefox for Android 79 was released I cannot upload an image to any website. For example the form where I am typing this question has a field Add images (optional):. When I click the Browse button below it, the system select dialog appears, I select an image and when I click Done, Firefox returns to the page and re-renders it as if the app is restarted, and the chosen image does not appear in the field. I noticed that if I spend very little time in the select file dialog, e.g. choose one of the recent images, the file selection is successful – it appears in the form field and can be uploaded. I don’t know if is connected to this issue but when I switch quickly (like less than 5 seconds) to a messaging app to retrieve anaccess code for example, the page is re-rendered again. Tried installing and uninstalling to no avail. Reinstalled the last version before the Firefix Daylight upgrade, 69.11.0, and there I had no problem. I am using Samsung Galaxy A10 with Androud 10.

i try to login on bahn.de. they redesigned the login-procedure recently. and with the new login it crashes the Firefox tab reproducible on my phone. i get the `Firefox can't load that page` message. on of the crash reports can be found at https://crash-stats.mozilla.org/report/index/d3962d01-f863-4f6c-908d-3d4af0211103

i have cleaned up with `Privacy and Security` - `Delete browsing data` (all options set) and also did clean the cash for the firefox app from the system settings.

the url is (i removed the nonce and state values) https://accounts.bahn.de/auth/realms/db/protocol/openid-connect/auth?cancel_uri=https%3A%2F%2Ffahrkarten.bahn.de%2Fprivatkunde%2Flogin%2Fidmredirect.post%3Flang%3Dde%26country%3DDEU%26scope%3DCANCEL&showRegisterWithBahnCard=true&kc_locale=de&showSoftLogin=true&scope=openid&response_type=code&redirect_uri=https%3A%2F%2Ffahrkarten.bahn.de%2Fprivatkunde%2Flogin%2Fidmredirect.post%3Flang%3Dde%26country%3DDEU%26scope%3DRETURN&state=0&showReloginMessage=false&nonce=0&client_id=fe_esuite

the original url was 551 characters long.

my first impression was that the url may be to long.. i tried to shorten it - https://accounts.bahn.de/auth/realms/db/protocol/openid-connect/auth?cancel_uri=https%3A%2F%2Fbahn.de&kc_locale=de&showSoftLogin=true&scope=openid&response_type=code&redirect_uri=https%3A%2F%2Ffahrkarten.bahn.de&state=0&nonce=0&client_id=fe_esuite (247 characters) this one worked in the desktop browser but also crashes in firefox android. the crash happens latest when i click on the `Angemeldet bleiben` checkbox. on a next try it happened shortly after the loading without user interaction.

Firefox Version: ``` 93.2.0 (Build #2015839745) AC: 93.0.12, e39f5dba3f GV: 93.0-20210927210923 AS: 82.1.0 ```

OS ``` Android 7.1.2 LineageOS 14.1 ``` and yes - i know this is a very outdated OS version...

the main problem is that this login is needed to authenticate in the *db navigator app*.

with some workarounds i managed to do a successful login in the app:

• switch system default browser to the *stock browser* app
• click login button in *db navigator app*
• stock browser opens with login page
• fill in & click login
• stock browser does not know how to handle returned url (example below)
• copy returned url to clipboard
• open firefox
• past url
• open menu and click on *open in app*
• *db navigator app* launches and accepts the login
• i am happy again ;-)

hopefully this is only the case for such old OS versions and this way does not effect anyone else...

are there any other things i can do for better fix the issue in the first place?

Every time I open Firefox it always start from the last page I had visited before, I'd like to change that and have it to start from the browser home page.... tried few things with no luck.... any help folks? Thank you

I'm using Firefox on a Samsung moto G6 with Android 9. When I open Firefox it displays a yellow page that says XML Parsing Error: no root element found. Location: chrome://geckoview/content/geckoview.xhtml line number 1, column 1.

I can't open any pages. I've tried restarting my device but I still get the message. What should I do?
