Firefox for Android Support Forum

Formatted my phone but playing videos still lags and stutters on Firefox browser on my Samsung. Only happens on Firefox, I've tested on Qwant, Duckduckgo and Brave and this problem doesn't occur. What might be the problem and solution?

It's interesting that sometimes the video plays fine until I unmute it. Sometimes the problem goes away after I stop and play or refresh the page. I often have to play the video on a different browser.

So, videos work fine on other browsers so I discart being a phone problem. But on my other phone this problem doesn't happen with firefox.

I've been for several months looking for help/answer/fix for this issue. And I've been with firefox for ever and I don't mind minor bugs and problems but this is starting to be a bit annoying and more and more I feel like I need to move on to a new browser.

Firefox is very dear to me. I use it on my computer all the time for how much more relatively secure it is from other browsers. But Android version is a hellish nightmare. When I open the app, even with no previous tabs on, it will not be responsive for more than 30-45 seconds for seemingly no reason. Same thing when I kill the app and start it again. If it does have open tabs, it will either not be able to fetch their sum number to be displayed on the top right corner until that aforementioned timespan passes, and/or I wont be able to remove/add tabs until again that period of time passes! This is a blocking issue that's been there for well over a year and a half, if not longer!

I setup sync, the device paired. It said it was syncing and when finished the bookmarks folder looked totally different on my kindle fire. I can not find any of the recently added bookmarks on the kindle. The History and Open Tabs are still the same, I didn't have those selected for sync. I checked and one password that I knew was previously incorrect on the kindle got updated to the correct one from the desktop. But I am worried about any possible passwords that were only on the kindle or were correct on the kindle and incorrect on the desktop, based on the bookmarks I suspect those were lost also. I was worried about this and had tried to find the profile data on the kindle but no file manager helped, I couldn't find it anywhere. And there doesn't seem to be a way to access profile manager on android. I also poked around with adb with no success. I was hoping to make a backup before using sync but I gave up and did sync anyway. Is there anyway to recover this data?

Everytime I try to open MediaFire it's just a blank page, I've refreshed the page repeatedly but it didn't work, I also tried with other links, but it also didn't work, I kept seeing the blank page over and over again.

1. Open the Firefox for Android application 2. Either browse around first, download something beforehand, or do it right at the start, go to the 'three dot' menu on the top right screen and select the 'Downloads' section. 3. The application will freeze without opening the section and after a while will say 'Firefox not responding' before crashing.

Hello,

I'm not able to upload files to certain websites using Firefox on Android.

When selecting a file for the phone's file manager, the file upload simply not starting.

However, Firefox on iOS doesn't have that issue.

Firefox version used is the latest one and it is the one from Google Play.

Tried another browser and it works great.

It seems like a difficult problem, which no one knows how to solve, not even Firefox (?) The problem has existed for a while and has not been recognized and resolved by Fiorefox. Very simple and straightforward problem: open a web page, give permission for location (this is indeed set in the settings) and the web page can determine the location. After closing the web page and restarting it, the location is blocked again, even though the settings states that Firefox still has access to the location.

When opening a website, the url has a padlock with a red line thru it (unsecured), the browser then waits about 5-8 seconds for the red line to disappear (secure )then begins loading the content. It behaves on win 10 and android devices. Upon refreshing Firefox on win 10, it got faster, but reverted. Unchecked wait for secure sites doesn't help.

The Site Notification for Firefox for Android is broken (don't know if it's just me) I have a notification for IGN website but Whenever I click on any site notification I received it always open a " about:blank " page rather than the actual website.

Despite updating to the latest Firefox version (127.0) and performing a reset, I continue to face high CPU usage issues. The battery monitor reports extensive CPU consumption for minimal use, even when only a single tab is open. This problem is not exclusive to the main Firefox app; it persists across other Firefox-based browsers as well.

Device: Xiaomi (HyperOS - Android 14) Issue: High CPU usage across multiple Firefox versions Troubleshooting Done: App reset, tried alternative Firefox-based browsers

I urge the development team to investigate this recurring issue, as it significantly affects the performance and battery life of mobile devices. Your prompt attention to this matter would be greatly appreciated by all users experiencing similar problems.

Hi,

Basically my self hosted jellyfin instance throws an error:

Corrupted Content Error

The page you are trying to view cannot be shown because an error in the data transmission was detected.

   Please contact the web site owners to inform them of this problem.

But on chrome it is working as expected. Any way i can check for errors in the android app?

When trying to access certain sites, I receive a message that " Access is denied. You do not have permission to access this website." I was trying to place an online order at Subway.

Hi,

I've been using firefox for 20 years and never experienced problems with webpage display until I started using it on my new phone samsung s23 ultra.

More often some webpages will not size correctly with my screen and is cut off so I have to switch to chrome.

For example, only 80% of this webpage is displayed. https://www.unsw.edu.au/newsroom/news/2024/04/pfas-forever-chemicals-above-drinking-water-guidelines-in-global-source-water

Is this a bug?

Thanks.

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.
