I am currently using Katalon 5.4.2, I only perform testing in chrome and all scripts running good, but recently i plan to do a trial run in FF and I noticed that the firefox not able to launch successfully.

Here is my finding  
katalon - 5.4.2  
Selenium - 3.7.1  
GeckoDriver - v0.19.0

In order to run the test with the latest FF, these are recommended

- Firefox 57 (and greater)
- Selenium 3.11 (and greater)
- GeckoDriver 0.21.0

Can katalon release the version follow the latest driver and align with the selenium version as well.
