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?

I am writing to request assistance with an issue I am encountering on the latest version of the Firefox browser for Android. My goal is to open specified pages in the same tab using Intent from a third-party custom application. However, I have observed that different URLs open in separate tabs, contrary to my expectations.  Current Implementation:  Here is the code snippet I am currently using: java： Intent intent = new Intent(Intent.ACTION_VIEW); intent.setData(uri); intent.putExtra(Browser.EXTRA_APPLICATION_ID, packageName); startActivity(intent); Expected Behavior:  I expect different URLs to open in the same tab without opening new tabs. This functionality is crucial for my application.  Issue Background:  I have researched similar issues and found that users have had comparable needs using Browser.EXTRA_APPLICATION_ID. Unfortunately, it appears that Firefox has not fully addressed this functionality. The EXTRA_APPLICATION_ID is a feature that modern browsers should ideally support to enhance user experience and maintain continuity within a single tab.  References:  I have referred to the following discussions and issues for additional context:  Mozilla Support Forum: https://support.mozilla.org/en-US/questions/1364869 GitHub Issue: https://github.com/mozilla-mobile/fenix/issues/23329 Request:  I kindly request that the Firefox team consider adapting this functionality officially or provide an alternative solution if it has already been addressed. Any relevant documentation or guidance on achieving this behavior would be highly appreciated.  Thank you for your time and assistance.

Issue 1: Why does Mozilla heat up so fast even though my device has no problems at all, and when will it be fixed? Because I've used Edge before, and it works very well and consumes little of my device resources. Issue 2 After the last update of Mozilla version 127.0.1, the use of in private mode became more difficult to use, and with my habit of keeping tabs open in private mode for a long time, sometimes up to 3 months. And I'd like to know when Mozilla will make it better for people who like to use it privately, because I don't like to use general mode, it's like there's constant surveillance for Mozilla users, and there are also cookies, so I don't like these and use them in privacy mode all the time I surf the web.And why is it harder for me to use it in In private mode? I have a hard time adjusting the buttons. I don't like the button that comes in place of the homepage button.

I've seen too many threads about this issue. This has been around for four years straight. No one ever managed to solve this problem and developers didn't care either. I've tried everything I've found so far: 1. Force sync on Android after sync on Desktop; 2. Disconnect and reconnect everything; 3. Uninstall and install again Firefox on both devices; 4. Clear data on both devices; 5. Login in different ways (e-mail, qr code, etc.); 6. Turn off one device, sync and turn on later; 7. Disconnect all other devices that isn't related with this problem; 8. Activate and deactivate 2 Factor login; Anyways, this sync feature doesn't seem to work at all. Almost all threads ended up abandoned, just like the app itself. Do anyone ever found a reliable solution for this?

Firefox for Android gets frozen when using it to open large PDF files. I have been meaning to change my default PDF viewer app, but once Firefox has been set as the default PDF viewer for Android, there will no way to change this default; as Firefox default's don't have the option to be deleted through Android's App Info menu.
