Import own data from ESR Firefox to normal Firefox?

I have the newest Firefox ESR browser (to go on using some extensions not available for the normal Firefox) and consider to better use the normal Firefox now and to not to use the incompatible (for the normal Firefox) add ons anymore. Is there a reason to not to change the ESR Firefox with the normal one?

How could I import / get all of my data to a normal Firefox? Is it enough to just copy the profile folder from the ESR to the normal one or to copy the the normal Firefox over the ESR?
