Steps to reproduce: 1) Open the project attached internally 2) Select 'Login with data binding sometimes fails' test 3) Select FireFox as execution browser and Run test Expected result: Simple log-in/out script executes successfully through all 10 iterations. Actual result: The first iteration will pass, however the next 9 may or may not. If they are to fail, it will be due to step 4 appending its text to the username instead of into the password field as expected. *Issue only seein in FireFox when test is data driven.
