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?

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.

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 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"

Hi, I just installed Firefox on my phone but I can't download add-ons (see attachments). My connection is fine, I tried disabling the VPN, but it's still the same. Please help. Thank you

Firefox 103.2.0 (Build #2015895963) Device: POCO F2 Pro

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?

So I have installed Firefox on my Galaxy S20 Plus running Android 12. All permissions are granted and everything is working except the camera. When testing it with https://webcammictest.com/ it ask for permission to use the camera and mic. I of cause allow the use and afterwards it says: The device is not found.

I have tested the mic alone and it is working. The test site is also working in Chrome, Edge, Vivaldi and Brave. So chromium browser do not have any issue with the camera or mic. I have also tried other tests sites with the same result.

I first noticed it when I had to call my doctor which sent a link to a site with camera feedback on. I was surprised and stressed about it wasn't working. Having a doctor waiting and a sick child, while installing Chrome to get it working, was not a fun experience.

When viewing a Reddit post, similar posts are shown below it. When in mobile view, if there's a video in these posts it start playing with sound when you scroll down a bit, irrespective of the browsers autoplay setting.

Crashing when ever upload any file to website, already given all permission (storage also)

When visiting this page, https://pluralkit.me/commands/#system-commands, and using "find in page" the find it page prompt just randomly closes. It happens a few ways. A few times I've been halfway through typing my search query, and on the third letter, the prompt & my keyboard disappear. Every other time I hit the "next item" button a few times and on the 1-6th time, the prompt disappears. I can re-open it but it loses my search query, and it's annoying.

I'm using Firefox

98.3.0 (Build #2015870331), b1a12ce69+ AC: 98.0.13, a31f2c481a GV: 98.0.2-20220322144853 AS: 91.0.1

On Android 12 (SP2A.220305.013.A3) on a Pixel 6 Pro. No add-ons. I've tried restarting the Firefox app.

Does not appear to happen on a few other websites I've tried.

Just a white screen today.

• Restarting device didn't help
• Settings > Apps > Firefox Nightly > Force stop didn't help

Android has an option to clear a cache, but I don't know whether that is safe. Would prefer not to clear data if possible to avoid.

I like to collect my tabs and delete my all tabs. Collection feature in Firefox let me collect tabs of my name choice, I really like this feature a lot but this feature has a bug

• Suppose I made collection of 3-4 number of tabs as list 1.
• Then i delete all the tabs
• Now when I go to my collection list 1 and select the open tab option from list, the tab comes back but again when I select open tab second time it also bring back all the tabs which was not even in the collection, and it keeps on bringing all the tabs you ever made irrespective of the collection list, though they not add to my collection list but when I open tabs from collection list it brings all the tabs which was deleted and they (tabs) even come back after clearing the browsing history also.

Please fix this problem, the solution which i recommend is

1. Collection of tabs should be separate form other browsing activity it should be like a copy which I can curate accordingly. 2. Collection list should not delete even after clearing the browsing history only by manually delete the collection list does so. 3. Give is the option of select all option for selecting tabs its very hard to select tabs one by one and then group them into my collection

Please fix this problem it's very annoying i have used collection feature in safari try to take hints from them.

When filling out online forms sometimes I need to check information on another app or when checking out of online purchase I need to go to my banking app to allow the purchase, whenever I go to another app or the screen locks when I go back to firefox the page has done refresh which in most instances, especially online forms, means I either get a timed out message or I am brought back to the beginning screen with all information I entered erased. For some online purchases I am never able to complete the transaction because I am sent back to beginning of the form everytime I approve the transaction in banking app. Any solutions?

I manage this website:

https://www.poderesantangelo.com/

On my desktop firefox displays the site without any problems, on my android mobile using firefox I see 'Error 521' with 'poderesantangelo.com Host Error'.

The same website displays without any problems if I access it using Chrome.

Do I need to contact my hosting provider as suggested by the same error message? Is this a bug in the latest version of firefox (which I am using)?

Thanks,

Graham Bradford

The 'pull down to refresh' feature is still missing. I was forced to install the most recent version of Firefox to appease the Android overlords, when I got the new S20. (Blackberry 5G still not ready...) The option to customize my gestures to refresh, is gone. When will this obvious feature be restored?
