donan So the new files created works correctly in both?
So, i guess in the new files you are using the same events conditions for X/Y coordinates, right?
In the new files are you using families too? If not, can you use Families like the .capx to see if this is the problem?
Can you post the .capx file on that NormalMap Extended works on both FIrefox/Chrome to see the differences, please?
Maybe there is also an option on "Project properties" that i marked/add on the examples that when you create a new one they are disabled.
If none of this things changes i don't know what more can be :S .
donan Will be great if you can try all that to see in what moment the NormalMap stop working on FireFox to avoid the problem.
