Tigra is not fully compatible with FF 3 (do not know how it is with FF2)
However in FF3 it is not fading in and out like in IE 7. After rollover on thumb, big picture is display immadietly without any fade in effect.
Also position of big picture seems to be strange. When you have gallery of 3 pictures and rollover on 1st thumb it is ok but when you roll over 2nd or 3rd the big picture display in the same place for both thumbs ?
Is there any way to fix this ?
re. transition. In feature set product page says: "Amazing transition effects (IE5+ only)"
and then in Compatibility Table again: "Note: Transition Effects are only supported in Internet Explorer v.5 or higher"
re. hint position: I just tried online demo using FF3 and hints appear in different locations as per configuration.
