Aircraft X was inbound from our western arrival gate to FLL. They were inbound to the airport descending for the approach. Aircraft Y; a VFR popup off of TMB who climbed to the northwest under the Miami finals; and was only known because of ADS-B who it was; cleared out from under the bravo and continued its climb up to 045 under the FLL finals. Aircraft X's descent had to be stopped; causing them to be high; unstable; and unsafe on the approach. This is not a safe way to work parallel runway traffic into FLL; needing to always stay high because VFRs are allowed to climb and fly willy-nilly through them.FLL airport is the 19th busiest airport in the USA; and one of the top 3 fastest growing; averaging 8% growth each of the last 5 years. FLL has a basic Class C airspace surrounding it that is beyond out of date and unable to aid in the safety of its aircraft on the finals. Planes inbound to each of their parallel runways are not offered any sort of protection until within 5 miles of the field; which allows several dozen VFRs each day to climb; descend; and transition across each final; without ATC advisories creating a very dangerous; unsafe; and hazardous situation in the skies above. The FLL Class C is inadequate; and out of date; and needs a major airspace change around it; whether a bigger Charlie; or a full blown Class B before it's too late.
Miami TRACON Controller reported an airborne conflict due to a VFR aircraft climbing into the FLL final.
