Hi Karen, normally you can remove defaults for your existing default browser using its Application settings. After you do that, under Launch by Default it should say "No defaults set." When you check that setting for Chrome or whatever is your current default browser, is it stubbornly staying the default or is that feature somehow broken?

There is a way to remove ALL default app preferences so Android should give you the choice for links or other types of documents/addresses, but I haven't tried it myself. When you are in Settings > Apps > "All" tap the menu button (3-dots or physical button depending on your device) and look for "Reset app preferences".

Oh, just to make sure we're discussing the same set of steps, our support article: Make Firefox the default browser on Android.

I tried everything you said but I dont know what to do after I reset app preferences please help
