Firefox za Android Support Forum

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.

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.
