Forum Firefox za Android zajednice

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.

(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.

Links won't respond to touch , scrolling up and down is fine , all other touch functions are fine , just links and tabs etc won't respond

Any help ? Wasn't like this before

I use Mozilla specifically to avoid the AI slop Google is pushing. I am deeply disappointed with all the AI scam bloatware suddenly slowing down my devices and compromising the integrity of my devices.

The new CEO is rapidly squandering over 20 years of trust I had in this company.

Deeply disappointed

My keyboard pops up randomly and semi-transparently while also being unusable. It's also preventing from interacting with the webpage behind it. Any ideas on how to fix it?

when I type in the search bar of Firefox I have to double tap the space bar to get a single space. quiries for solutions tell me to toggle a non existent option. tried different soft keyboards still happens. turned off predictive text on Samsung keyboard and it solved the space bar problem but I would rather switch browsers then turn predictive text. been using Firefox for decades don't really want to switch this issue will make me.

The primary issue I keep running into is that when I consume media within the browser, say browsing reddit or watching movies, the cache seems to fill up quickly to around about 500mb, and the crap hits the fan. Webpages don't load, error messages show up, tabs stop responding and become unusable, videos become irretrievable or buffer continuously, it sucks. I have it set to clear my cache when I quit from the menu but that doesn't work. So every time the app starts having an aneurysm I go into settings, force quit, and clear the cache. Firefox is the only browser I use, but because of this I'm no longer committed to it, I will happily trade it for something better when it comes along. I expect nothing to change.

I've got a very annoying bug in Firefox for Android. A lot of times it registers a tap as a pull from the top which results in a page refresh. This happens for example when I try to open hamburger menu's on websites.

I've added the app version details for more information.

Could you please have a look at this bug?

Poor *Cache* management is the main issue for me for starting... The *fevicons(app icons)* got disappeared after clearing cache and fetching fevicons is also hit & miss... The tabs frequently reloads even after only few minutes of inactivity or after opening other app for something like opening WhatsApp for reading message, then it get reloaded and progress get lost in critical things like filling forms...

• Shortcuts* menu on Homepage is limited to 16 and unallocated icons got filled with history, why!

Toolbar should be more thin and URI bar should be more broad, *Reader Mode* icon should be shifted to main menu... Dark mode for websites should apply without reloading tabs... Download manager is still poor, the queued items sticks to the notification panel and can't be removed even after pausing, it is only removing by deleting it...

STOP STOP STOP STOP STOP STOP STOP page reloads after losing and regaining focus! This bug makes it impossible to use FF for any tasks that require external authentication and is simply incredibly annoying!

Whenever I go back and forth between apps, there websites I have on Firefox gets reloaded. It is annoying and has been risky while on my banking website. This is why I have stopped using Firefox for any transaction related work.

Hello, Sometimes my browser is not reponsive when i open it. There is no apparent reason for why it does this. It doesn't load the last opened pages and does not load when i type a query. I have to reboot it several times sometimes before i can use the app again. This is not a major issue as i just use another browser in that case but you can consider this information as a datapoint for "potential bugs". This is exclusive to the app and not the browser.

Happy surfing :)

I am a big fan of firefox but i see some difference between firefox and chromium based browser that is Smoothness. All those scroll and swipe are beautifully smooth on Chromium based browser but in Firefox, it stutter and feeling visual lag. I know that Firefox is made by different engine but on IOS it's feels smooth but on Android it's sluggish. I hope you guys find a way to fix those problem.

Occasionally (it already happened three times today) when i'm browsing and switching between tabs, one tab will become an image of its contents (as in - no links work, can't scroll vertically or horizontally) and the others become grey. Trying to reload the pages or open new ones doesn't work, they never load. Turning the browser off by going to the phone's home menu and closing Firefox in the recent applications view doesn't solve the problem, it only closes any private tabs but the issue persists when opening any new tab or preexisting ones. The only way to fix the problem is by force stopping the app. I've cleared the cache, it didn't solve the problem, and reinstalling seemed to work for a few days but now the problem is back. For reference, my add-ons/extensions are: Ghostery, NoScript and UBlock Origin.

I use the NFC on my phone in order to tap onto a bracelet that gives me a daily scripture. It was working but the past few weeks it either doesn't download, is super slow and only may or may not load the whole thing. Once I uninstall and reinstall the app on my phone it works great. Sometimes it may work a day or even up to 3 days, but lately I'm having to uninstall and reinstall daily. Then I have to customize everything again. It is the same with webpages loading also. I clean the cache regularly and I've checked my internet connection and it's fine. Hopefully, this issue can be resolved. I'm using a Samsung Galaxy A52. This is only happening on the phone and although I can't use the bracelet on my laptop, I don't have any issues with Firefox. Should you need any additional information please let me know.

I used camera inside a tab and then closed the tab. I get the "Tap to open the tab that's using your camera." notification. If I tap it redirects me to home page in Firefox. If I swipe right or left won't close the notification (seems to be glued).

It's the second time I'm confronting this. It disappears only if I restart the phone.

When switching apps from Firefox to other apps, it almost always reloads the webpage. This is annoying in the certain scenarios

1. After I enter my username, it goes to a password page. I switch app to my password manager to copy my password. Comes back to Firefox and it refreshes, going back to username screen. Impossible to login. 2. After I enter my username and password, I need to go to SMS or Outlook app or Authenticator app to obtain the MFA code. Comes back to Firefox and it refreshes, going back to the login screen. Impossible to login.

This happens to various websites. I have no issue with Chrome or Brave on the same phone. I even tried terminating all apps leaving with just Firefox and the same symptom happens. Memory is sufficient, my phone has 12GB of RAM.
