Firefox doesn't let Swype do its auto-spacing thing

For every version of Swype I've had -- orig beta, pre-installed on device & newest beta -- Swype had a setting where it would automatically put in a space when you paused between words. For every mobile version of Firefox I've had -- Aurora & official release v14 -- Swype's auto-spacing never works. Not sure, but I don't think it's a Swype issue since auto-spacing works in every other app, but hasn't ever worked w/ FF. I'll do whatever I can do to help troubleshoot this issue...just ask/tell me since I'm stumped & don't know what to do next :)
