Hi airgg,
what kind of error / stacktrace do you see?
I'm not sure if this can help, but I would start by checking if all dependencies necessary to run JSF & the extensions you use are provided. Tomcat being a servlet container, it does not provide a number of things, such as e.g. the JSTL libraries and dependency injection container functionality.
That is, the issue you describe seems to indicate that the extensions work on one browser (Chrome) but not on others (Firefox, ...). Maybe with a more detailed error message / description, it'd be possible to help.
Cheers,
Manuel
