On Firefox 120.0.1 when I clic a whatsapp link, for example https://wa.me/########## where # is the number, it opens the webpage and has the message Whatsapp is not installed. Opening the same link with Desktop Site enabled, works fine. The behavior is the same using api.whatsapp.com/send?phone=##########

Open links on app setting is enabled to always and other app links are working ok.

I'm using Whatsapp Business app on Android 13 Xiaomi Miui 14 Phone

On Chrome for Android and Edge for Android it works ok

Please help me to stop this tab hibernation, I'm literally been miserable because of it, can't do any important things.

How to turn on strictly keep all tabs stays as I left it ?

Hope you help

The default font in Firefox Android is Roboto, and I want to change the default font to the system default font or a font I downloaded locally. I can't find any settings in Firefox Android regarding font settings. about:config doesn't seem to work on Android. How do I change the default font in Firefox Android, like in Firefox Windows?

Hello.

I recently started using Firefox browser on Android mobile OS, and am having trouble with Korean letter URLs.

On Firefox, unlike Chrome or built-in Samsung internet browser, URLs containing Hangul are displayed ASCII code on every page.

For example, this is how the URL of '모질라 파이어폭스' article on korean wikipedia is displayed.

https://ko.m.wikipedia.org/wiki/%EB%AA%A8%EC%A7%88%EB%9D%BC_%ED%8C%8C%EC%9D%B4%EC%96%B4%ED%8F%AD%EC%8A%A4

As you can see, it is totally a mess and very uncomfortable when it comes to sharing or modifing an URL.

I tried turning off HTTPS-Only Mode in settings however it didn't work.

My idea is that changing the browser's encoding setting from ASCII to UTF-8 will help, but I can't find any option for it.

Is there any solution or add-on to solve this problem?

Sorry if my English reads awkward. But I believe that you could understand my situation.

Version info 120.0.1 (Build #2015988378), a61decd90e+ GV: 120.0.1-20231127143053 AS: 120.0.1

Noticed my phone having terrible battery life, from battery usage you can see that Firefox is highly likely one of the main culprits. I have observed the same over a few days on the last two Firefox builds. It seems that it's not respecting the "Restricted" battery usage in Android (or Android is not restricting it, I have no idea), but you can see today's battery usage linked here: https://photos.app.goo.gl/pMByjqq6Q5GigcQu8

Hello fam.

I just downloaded an extension of a particular app. It's expected that the app automatically connects with the browser as I click to join them but it keeps failing. How do I rectify this?

Hello,

Quite à few month ago, after update, my new Firefox for Android does not allow me to access to the print option. I cannot find the page nor the tools options using my mobile. When using edge, chrome or other browser, I still do have this option and therefore able to print pdf copies of the resources I do want to archive. Is it possible to know why these printing options are unaccessible on Firefox using Android ?

How do I stop Firefox mobile from refreshing every time I leave the app and come back? This wouldn't be such a big issue expect for the fact that I use bitwarden as my password manager. So every time I want to enter my password bitwarden leaves Firefox so I can unlock my vault. Then when I re-enter Firefox Bitwarden is unable to fill in the username and password cause the page is refreshing. Sometimes it even takes me out of the password page because the login screen for the site is a pop-up. Not a separate window.

This also becomes super annoying when filling out any forms and I need to grab info from another app cause a lot of time on form pages when you refresh the page the form gets cleared. It's at it's worst if I have to leave Firefox to copy and paste multiple items because then I copy one item, re enter Firefox paste, leave Firefox to copy the next item, re enter Firefox and the thing I pasted before is gone because the page refreshed! STOP REFRESHING THE PAGE EVERY TIME I LEAVE AND RENTER THE APP!!! It doesn't matter if I leave for mear seconds or used the recent app section to quickly switch between Firefox and another app.

I am on a Samsung Galaxy S20 FE.

About:config simply shows me a blank screen.

I need to customize a few settings and I presently cannot. This question marks this as answered but the answer is talking about a solution to the specific reason they were trying to access about:config, not why they cannot access it. https://support.mozilla.org/en-US/questions/1373286

Others say to use the nightly build, which I don't want. https://support.mozilla.org/en-US/questions/1302626

What's the deal? I've spent an hour or so now looking this up and haven't found anything.

I'm having a problem with playing videos on websites. When I click the expand to full screen button about half the time the full screen video comes up for half a second and then the window shrinks down to a small square on the bottom right-hand corner of my screen. Sort of like when the youtube app minimizes a video. This window is unclickable and also everything at or below it in android is unclickable while it's there. If I click the window button on android and swipe the firefox app up to close it and restart it, Firefox doesn't even close and I can still hear sound from the video. I have to select on the Firefox app again which will restore the full window and then click the full screen button one more time and it will work. This issue is happening on every website I play video on on the Firefox app and it is extremely irritating. I'm about ready to switch to another app if this can't be solved, but Firefox is the only browser that allows ublock origin so I don't want to do that. Can anyone help?
