Nothing stops you from developing on Chrome and using Firefox for general web browsing. Presumably, you don't need an ad blocker to test and debug your own code, unless you are testing specifically for ad-blocking browsers. And if you are doing things properly, you should be testing on both browsers anyways, at least as a final step.
