Android open link in Mozilla Firefox app in the current open tab

I have a very specific requirement: I need to open a URL link in a browser (not in a WebView), and I need it to open in the currently open tab, i.e. the opened page should be a "redirect" (meaning in the same tab).

Based on a consensus of multiple SO posts (see below), the way to do this is as follows:

Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(uri);
intent.putExtra(Browser.EXTRA_APPLICATION_ID, packageName);
startActivity(intent);

Specifically it is Browser.EXTRA_APPLICATION_ID that instructs the browser to open the link in the same tab:

Now in theory, this is supposed to work with all browsers.

Here it is important to note that packageName above needs to be the package name of the BROWSER that one wishes to open (e.g. com.android.chrome or org.mozilla.firefox), not the package name of your app.

Even though the documentation asks that you use the package name of your own app, it doesn't open the link in the currently open tab if you use the package name of your own app. Both Chrome & Firefox will open the link in a new tab.

So the trick to getting this to work is to set packageName as com.android.chrome, and voilà, Chrome opens the link in the currently open tab. Yay!

The same trick does not work with Firefox.

How can I make this work generally with any/all browsers?

Apparently this is a known issue with Firefox:

A. Firefox doesn't handle the flag Browser.EXTRA_APPLICATION_ID from an Intent.

B. Android Mozilla FireFox not opening page in a new tab.

Has this bug been fixed? Is there a known way to make Firefox open the link in the same tab?

How can I make this work for any/all browsers?

It doesn't seem to be supported; AndroidManifest.xml shows the intent-filter ... and newTab = session == null and newTab = true are hard-coded. Unless this gets filed as a feature request - or an eventual PR, which enables this will get merged, this won't happen (and even then, it would only be supported in later versions).
