Firefox for Android Community Forum

in previous versions the 3 dots menu would open up the newer redesigned main menu that fills the lower 2/3rds of the screen by default, but by enabling debug settings and going into Nimbus Experiments and disabling "Android UI Redesign - Release" it could be changed back to the older, more compact dropdown-styled menu. as of one of the recent updates, the "Android UI Redesign - Release" toggle seemingly does nothing.

I preferred the older menu for several reasons. one issue being that the new menu lacks a new tab button. the others being that it just _feels_ subtly yet annoyingly worse in just about every way.

so, is there any way to still use this old menu, via about:config settings or something? or am I just SOL and need to figure out how to downgrade my version?

.htaccess .htpasswdでアクセス制限されたサイトがあります。 アクセス制限したサイトに ID,PASSWORD でログインしてページを見ることはできます。 画像も正しく表示されます。 しかし、「画像を保存」すると「ダウンロードに失敗しました」と表示されて画像を保存できません。 同じことを Chrome でした場合は画像をダウンロード、保存できます。

I have a site with restricted access using .htaccess and .htpasswd. I can log in to the restricted site with my ID and password and view the pages. Images are also displayed correctly. However, when I try to "save image," I get the message "Download failed" and can't save the image. When I do the same thing in Chrome, I can download and save the image.

Syncing tabs, passwords are very useful, but it is quite disappointing that there are no available option (during synchronization) to select Collections as well... Or am I missing some obvious way to do that ?

Trying to sync tabs with my desktop machine. Following the screen instructions, I am signed into my Firefox account on both the phone and desktop, a QR code is displayed on the desktop machine, but there is no "Ready to Scan" button on the phone. What now?

Since the latest update (v147), the address bar behaves like a normal text input rather than a URL input. This means that if I want to type, say, "google.com", it will autocorrect to "Google. com" (including the space). So every time I want to type a URL, I have to delete the space after every dot. It's very annoying.

I'm running a stock Pixel 9 Pro with all OS updates and standard GBoard keyboard. The problem persists with Firefox 147.0.1

I've recently updated to the latest version of Firefox on mobile and I HATE IT!! Everything was absolutely fine before they overhauled the ENTIRE UI. Need help going back to the latest previous version.

When I go to the firefox website and tap on the microphone to ask a question the Google speech services comes up and I cannot adjust the loud volume on your settings or the phone Google settings. I have a Samsung Galaxy A25 5g phone and on Android 16. I have tried finelock sound assistant and that does not help. Is there an extension that Firefox has that I can use to adjust the volume when tapping on the microphone on Firefox?

I also have a Lenovo Tab M9 9" HD Tablet that has the Android 13 version on it and have no problem at all adjusting the microphone volume on that through the tablet setting.

Up until recent versions, I had the option to choose after what duration of inactivity, all open private tabs would close automatically. After the recent update, I can't locate this setting. Moreover, the duration is now not just non customizable, but also random. Sometimes, Firefox closes them in a couple of minutes, sometimes 20, and after more than an hour at other times.

Today, using Firefox--or at least what i think is Firefox--i checed session history while logged into my mega.nz account. It lists 2 instances, one of which is for 3 days prior when I originally set up the Mega account using the Mega app, and the other is for yesterday when I entered the account using the FF browser--or, again, what i think is the FF browser. What's curious is that it shows i was using the Chrome browser, and that I'm apparently still using this browser as it's listed as the "Current" session. How can this be? While I have the Chrome app on my phone, I disabled it long ago and have never used it, and most certainly did not use it during the time and activities in question. I have long speculated that I have been hacked and that my phone is sometimes (always?) controlled by this hacker, though no solid proof. Assuming the hacker uses Chrome, could this be reflecting their using the Chrome browser, as opposed to the FF browser, which I'm currently using (or think im using)? In other words, is this the proof of a hack? Or is this a glitch within Mega, mistakingly listing Chrome as my browser?

Which data are stored in "User Data" and how to clear this kind of stored data? When deleting data in the privacy settings in Firefox, the "User Data" storage is still unchanged. Also "Cache" is not cleared completely.

The "User Data" raises up to 1GB. It is only possible to clear it by completely wiping all data via "Clear Storage" but then everything is wiped, also all Firefox settings etc. "Clear Cache" obviously only wipes the Cache.

Hi everyone,

I’m using Firefox for Android on a fairly recent device and wanted to ask about performance when running web-based applications that are a bit heavier than normal websites.

Specifically, when using browser-based emulation tools or interactive web apps, I notice higher memory usage, occasional tab reloads, and sometimes audio or input lag after a few minutes. This doesn’t always happen on simpler sites, so it feels related to how Firefox handles long-running JavaScript and WebAssembly workloads on Android.

I wanted to ask:

Are there any recommended Firefox settings or flags to improve performance for heavier web apps?

Is Firefox for Android known to aggressively suspend tabs under memory pressure?

Would using private tabs, disabling certain features, or changing about: config settings help in this case?

I’m mainly trying to understand whether this is expected behavior or if there are optimizations I can apply.

Thanks in advance for any guidance.

I regularly visit a site whose URL begins with "ni". When I type "ni", the full URL appears an an autofill suggestion. This is the desired behaviour.

Unfortunately, after visiting the site "nitecruzr.blogspot.com", this site is autofilled when I type "ni".

Firefox's documentation sais that if I delete the page from my history, it won't autofill again. Unfortunately, after deleting the page, this site still autofills when I type "ni".

How can I actually remove this site from address-bar autofill?

In Firefox Mobile app... When I click Print option (for print pdf) It opens default printing app and it opens default letter format with header footer automatically added to the page

There is no option to remove header footer (this only appears in Firefox print...)

2nd problem is when I switch to landscape print it just shrink the letter size to the left and right half page is blank... Not responsive.. not automatically fits to the paper size... You can check the attachment for visuals of the problem.. Please fix this adjustment and header footer link problem or provide built it browser printer for custom printing options before launching the printing app.

My mobile app Firefox keeps crashing on starting it reinstalling doesn't help it used to work at some point but now it doesn't.

My phone is OnePlus 13 it has the latest EU updates. I can't seem to figure out why it crashes.

I installed the latest version from the Google play store. Other versions of Firefox work fine like nightly or beta only the main one crashes.

When I go to the firefox website and tap on the microphone to ask a question the Google speech services comes up and I cannot adjust the loud volume on your settings or the phone Google settings. I have a Samsung Galaxy A25 5g phone and on Android 16. I have tried finelock sound assistant and that does not help.

(1) Page become blank and only show big firefox logo everytime i switch from other app.

(2) after the page become blank, If you type new url in the url bar on this page, it doesn't go to your URL instead the page will refresh to the previous url. So you have to enter your URL twice. It look like some memory issue, but my phone has 12 GB RAM, run on latest android and hyperOS 3.0

This good browser become barely usable with this annoying bug. So please fix this issue.
