On my Android 4.2.2 Jelly Bean device, the links opened in the Facebook app, open up in Firefox' Custom Tab. I want to disable this behavior and just open up the tabs normally in Firefox. Firefox is my default browser.
On my Android 4.4.2 KitKat device, this can be disabled in Firefox by going to Firefox' Settings → General → uncheck 'Custom Tabs'.
However, on my Jelly Bean device, I noticed that the 'Custom Tabs' option is missing in Settings → General. Is there a way to disable Firefox' Custom Tabs in Jelly Bean? Could there be an 'about:config' preference that I can modify?
The Facebook app and Firefox (68.1) are updated to their current latest versions from Google Play Store as of the time of writing.
