This release candidate for the upcoming version QF-Test 4.0.2 provides support for Firefox 33 and fixes a critical WebStart issue caused by the latest Java updates 7u71, 7u72 and 8u25.
The final QF-Test 4.0.2 version is going to follow next week after more thorough testing with these Java updates. Unless you require one of the technologies above, we recommend to wait until then.
