Firefox for Android Support Forum

This is a follow-on to https://support.mozilla.org/en-US/questions/1401783, I have the same problem - I've followed https://support.mozilla.org/en-US/kb/extended-add-support (which is for some bizarre reason marked "no longer maintained"), to create the custom collection https://addons.mozilla.org/en-US/firefox/collections/17515772/raxod502/ so that I can override the arbitrary blocking of third-party extensions that Mozilla applies by default.

This allows me to install most extensions but for some reason https://addons.mozilla.org/en-US/firefox/addon/duochrome/ is not showing up in the interface on Firefox for Android, despite being in the custom collection. No information is given about why it is not showing up. I am not aware of any reason why it would be blocked. Here's the manifest.json: https://github.com/FreshSupaSulley/Duochrome/blob/main/firefox/manifest.json

How can I fix this and use whatever extensions I want to use, or at least get a valid error message about why Mozilla is blocking the extension?

Creating a new thread since the older one just says "Even using that approach, not all add-ons are supported in Firefox for Android at the present time", which doesn't help at all - there is no reason why any addon should be blocked for mobile usage unless it is explicitly configured as such, and even if that were reasonable, it doesn't help explain what specifically is wrong with the extension I'm trying to install.

Firefox recently got so much slower than normal. Usually it will take 5-10sec to load a full page .Now it loads very slow that I don't know how much time it takes to fully load the page.please help me with this problem. Thankyou

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.

My phone model is ZTE Blade V50 Vita ZTE 8550 Running android 13

In Android 14 oneUI 6.0 i have an issue while i download, the progress of download doesn't show up, i have checked everything but only the Firefox notification of private search shows up, plus when it is downloading the file i have problems when browsing, like when i use the keyboard The keyboard automatically closes and doesn't allows me to type I don't know if i explain myself clear enough

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.
