                        progressBar.setVisibility(View.GONE);
                    }
                }
            });

on EditProfile.java (error)

 saveBtn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (editFullName.getText().toString().isEmpty() || editEmail.getText().toString().isEmpty()
                        || editPhone.getText().toString().isEmpty()) {
                    Toast.makeText(EditProfile.this, "All Fields Are Required.", Toast.LENGTH_SHORT).show();
                    return;
                }

                String email = editEmail.getText().toString();
                user.updateEmail(email).addOnSuccessListener(new OnSuccessListener<Void>() {
                    @Override
                    public void onSuccess(Void unused) {
                        DocumentReference docRef = fStore.collection("users").document(user.getUid());
                        Map<String, Object> edited = new HashMap<>();
                        edited.put("email", email);
                        edited.put("fName", editFullName.getText().toString());
                        edited.put("phone", editPhone.getText().toString());
                        docRef.update(edited);
                        Toast.makeText(EditProfile.this, "Email Changed Successfully.", Toast.LENGTH_SHORT).show();
                    }
                }).addOnFailureListener(new OnFailureListener() {
                    @Override
                    public void onFailure(@NonNull Exception e) {
                        Toast.makeText(EditProfile.this, "Error!", Toast.LENGTH_SHORT).show();
                    }
                });
            }
        });

here is where the error line

DocumentReference docRef = fStore.collection("users").document(user.getUid());

in collection sentence.
