Firefox for Android Support Forum

What steps can I take to troubleshoot and resolve issues with loading an entertainment site on Mozilla Firefox, such as videos not playing, pages not loading correctly, or other site functionality not working as expected?"

Hi. I can't watch a video on any website after updating my android app to v.(126.0 I think) because it plays Stuttery and laggy. I don't have much tab open, mainly 2 or 3 and incognito mode doesn't makes any difference. Still videos play laggy as if it's on low fps. The recent update to v126.0.1 didn't fix it either. My phone is galaxy s21 ultra if it matters.

I keep running into this bug where, on the odd occasion I am trying to download a file and the download occurs slow sometimes from the server's end, I might start a download of the same file twice. Then when one finishes downloading, if I press cancel on the ongoing download, it deletes the other downloaded file from my storage. This probably happens because the files are named the exact same but cancelling a downloading file should not delete an already downloaded, different file.

I was using foxfilter extension on spin browser in android and spin uses Firefox at it's core . The extension used to work well until some point in the past and suddenly it stopped working . I reached out to foxfilter support and they told Firefox stopped supporting some extensions on Android and thus the issue . Is there anyway you could start supporting foxfilter on firefox Android or can i use an olderversion of firefox on Android to get foxfilter working . If so could you guide me how to get that version installed ?

When I click on a web push notification in Firefox on Android, the link in the notification does not open. If no page is previously open in the browser, a blank tab appears. If another page is open, that page is displayed.

I just switched over from Chrome and am setting up my browser, and it seems I cannot select my country for an Address in Autofill? Wtf is that about? I'm an American who lives in Australia (dunno if it matters but I use US English) and my residence is in Australia. But the only two countries selectable are US & Canada... As if there are no other countries out there in the world where people live. How do I fix this? It's incredibly frustrating not to have, and makes zero sense to me why it would be a restriction - I have never seen any other use of countries in a form where it is restricted.

I really like this app. I always use it on desktop also but after a few last updates I noticed that battery usage of this app increased a lot and the percentage is very high. 1 hour screen time on youtube was 4% battery usage but on the firefox side it was 17 min / 11% battery usage. If you fix this It will be perfect for me. Here are the screenshots with different days. And I'm using sync feature and ublock addon. I always close the opened apps and I use deep sleep feature on my samsung device. And I forced to close the app. For now I stop using firefox for test purposes.

Dear Sir

I can not open Firefox Support mozilla in my Tablet ? Would you please give me the instructions ?

Thank you . Regards .

Louise.

Out of nowhere, the browser stopped when I was browsing and the pages started showing slowness. 👇🏻👇🏻👇🏻

When I finally decided to start organizing my hundreds of bookmarks, I began to experience a crash every 1-2 minutes. I'm opening, editing and moving bookmarks into different folders, which by itself shouldn't cause frequent crashes. My phone's specs shouldn't be an issue either since I have an s24 ultra. I'm grateful for any replies, and would like to thank you for your time.

I just opened firefox on my samsung galaxy note 8 and all of my tabs are gone. I have not seen the "restore previous sessions" option, nor are they in the "recently closed tabs" part of my history. Please help. Is there any way to restore the tabs?

Listening to audiobooks made me notice this problem, often whilst my phone is turned off and the audiobook is playing in the background on a tab on firefox the audio would just stop and i would find either that firefox was still open but unloaded all the tabs, or that it simply crashed. I thought this was a thing that solely happened when playing audio in the background but then i noticed that it is actually a general problem when firefox is kept open in the background. It doesnt happen after a set amount of time, sometimes it happens immediately, sometimes after like 10 minutes that it is kept in the background. How can i fix this? its very annoying.

From the image below, I asked a question and the results are there. I've tried this on my tablet as well, getting the exact sane results, no matter what I put in the search results.

However, I choose Google as the search engine (as you can see from the image below), while Firefox still being the main browser and I got results to the question below.

What is happening with your browser or duckduckgo search engine? In all my years of using these platforms, I've never had this issue. Yes, I'm Android user and haven't changed any devices. My setup is the sane on all my devices.
