Diễn đàn hỗ trợ Firefox dành cho Android

I need to adjust settings in about:config but it just loads a blank page. I have tried clearing storage and cache and even reinstalling but it won't work. How can I get access to this?

There used to be a forward arrow option in the three button menu. Now there is not and I cannot find out where it is or how to navigate forward.

This seems like a bug because navigating forward is a core function of browsing. Anyone know where it went or how to fix this?

On the latest Firefox Nightly builds (I use Nightly for extensions), holding the back button in the Android navigation bar no longer brings up previous pages, like it does when holding the back button in the three dot menu. Is there a config option to bring this back?

I own a Samsung Fold 5 phone. I have set the outer display used when the phone is folded to 300dp. The inner unfolded width is set to 601dp.

Up until very recently, when I folded or unfolded my phone, websites would resize. Often switching between layouts made for phones and layouts made for tablets or desktops. This still happens in Chrome. But no longer does in Firefox. Instead the site has the same resolution in both modes, making the text too small to read when folded. This effectively makes Firefox unusable unless I unfold my phone. Please make Firefox respect the resolution I have set for each mode again so I can view websites at a width of 300px in folded mode like I used to.

Note I have the slider for "desktop site" turned off. When I try to turn it on, nothing happens. The slider doesn't activate and the resolution does not change. (But the page does reload.) This used to give me the option of 3 different resolutions for my screen, (300 folded, 601 unfolded, and something like 1024 in desktop mode.) I'm not sure if desktop mode is permanently turned on now, or if the phone is set to permanently use 601 width, but it is definitely not using the 300 width I used to get when folded. The desktop mode slider is to the left and will not change.

I opened site settings and turned off always request desktop site and nohing changed. I am still unable to get the 300 width site I need to be able to use Firefox on a folded phone.

Hello all,

I am using Cambridge Dictionary regularly. In that site, when I try to listen how a word is spelled in the US, the last part of the word is not spelled. For example, I am trying to learn how to say " strut ", in the UK version, I hear it completely. But for the US version, I hear "stru" with no t sound. This happens for each word and this problem only occurs in Mozilla Firefox both in Android and on Windows. Is there a way to solve this or I will completely stop using Firefox as I need to use this dictionary very regularly.

When using Firefox on Android for a while, attempting to use pinch to zoom on a web site will cause Android to crash, as in the screen will go black, the G logo animation will appear, and I'll be sent back to the lock screen. It's not just the app that crashes. It doesn't seem to be a full reboot as that takes longer and starts with a different animation, but some part of Android is restarting.

It's consistent but not predictable. Pinch to zoom will work on one site fine and then crash on the same site later. It seems to be a resource issue as it's unlikely to happen on a fresh instance and it becomes more likely the longer you've been using Firefox.

This has been happening for several months, since at least July. It's happened both on my old Pixel 6 Pro and my new Pixel 9 Pro. It's happened on both Android 14 and 15.

I eventually found out I could go to Settings > About Firefox > Crashes and get some debugging info, but I don't know what to do with it. I currently have 15 crashes between now and Oct 16th which all say:

java.lang.RuntimeException: Adding window failed

Clicking Share to get more info on the latest one adds:

I don't know what to do with this info. Should I file a Bugzilla report with just this? The GUID associated with the most recent one is 7a5e5497-bb62-4e3c-94fc-5c63c51d0830. I can't look it up in crash-stats.mozilla.org. Or should I assume all crash reports are automatically received? I'd still like to be able to have a Bugzilla bug to watch for progress.

using uBlock Original & AdGuard AdBlocker on 22 Ultra with one UI 6.1, android v 14, security 11-1-24, it worked flawlessly until about 2 weeks ago. Updated everything, including extensions. removed & reinstalled, makes no difference. May as well go to iphone if i cant get it fixed now! Thanks

Dear Mozilla, Here are still some people (including me) who are using Low-end devices with poor specifications in our country like (Bangladesh) So, please Bring back support for Firefox lite! and at least make it available in play store of our region! We Need it! Please! Every time my family member or anyone who uses low end device, Firefox actual app lags in there, while old lite version worked perfectly before! so please bring back support and give us a favor!

Since Firefox nowdays is Multilanguage,but the downside is that when I choose one language( let us say English- UK or US).

Every time I visit any site it automaticly associate every site as if I were in England( or US). This also include ( based on my search history) that it also via default search for English websites. Since lagre multilanguage corporations have local websites as well.

But however in older versions it never had this issues. However for me it's quite disturbing( annoying). Since I myself live in Sweden( and isn't so interested of what happends in the states or england) Can some one please change( make correction).

I have a Tablet which I use for everything and I often need to browse and use websites. One day all websites were suddenly completely off in scaing. It's like I am browsing on my phone, but only looking at the top third of the website. I don't thing that I have changed any settings as it was just like that the next day.

it's exhausting and seriously disruptive

Hi, my browser on my tablet keeps making all tabs stuck in desktop mode with no way to turn it off. It started happening today when it updated to the latest Firefox Android 133. The desktop mode toggle is set to off, and when I click it it still is set to off and it's still in Desktop mode. When I copy the URL to another tab I can turn desktop mode off, but that gets reset to on whenever the browser is killed in the background.

I've tried force closing the app and clearing cache, any help would be appreciated.

Even though destop site mode in the pull down menu on the right is turned off it's affecting my site like it's turned on. I also can't turn it on to turn it off since it just stays off when I click on it. Also I'm not sure if this helps but everything now opens as a destop site instead of phone site when I open something new.

Hey guys,

I'm using firefox mobile on a lenovo p11 tablet with android 11. Yesterday, everything was fine. This morning I'm opening firefox and every site I visit is huge. Like, really huge. It looks like it is zoomed in, but the max zoom out state is still huge.

It turns out that desktop mode doesn't work anymore, because firefox 133 was installed overnight on my tablet. If you toggle it in the 3 dot menu, the site just reloads but if you check the menue after that it's deactivated again. This happens with the new option (always load desktop mode under website settings) on and off.

Most mobile sites are terrible on tablets since most of the screen real estate is completely wasted by way too big fonts, sidebars, etc.

Is there a workaround for this?

Also, is this a known issue, or should I report it on bugzilla or something?

Cheers

Hello!

A web site I frequent, livebyliving.org, has a menu structure running horizontally across the top of the pages. Each option has a pull-down sub-menu. Yesterday afternoon or evening that menu turned into the three bar menu icon in the upper corner of the pages and the horizontal menu disappeared. When I click the three bar icon the entire menu structure is displayed vertically.

Firefox on my Android tablet was updated November 26. I used the site in question numerous times since that update and the menu was displayed correctly. It displayed correctly yesterday morning, Nov 29. In the evening, when I went to use the site, the menu behavior had changed. I also note the change when using my Android phone. The last Android update for my tablet was February 6, 2023.

I tested with Chrome and Google today and they display the menu correctly so it seems as if something specific to Firefox changed yesterday.

I've attached three screen shots. The first is the correct behavior with the horizontal menu. The second image shows the same page with the changed menu presentation. The third image shows the sub-menu presentation after whatever changed.

Any thoughts would be most appreciated!

Check yo self, before you reck yo self!

My presets/shortcuts on android have dissappeared.

Last chance, mate.
