... FF has got this wrong. They have gone to all the trouble to get "Local Run" available for the FF desktop app, and then slap on a restriction only offering it on the paid version... so I have to pay to develop my MVP? If FF team opens this up to free tier users you will get many more customers and future paid users for FF. It doesn't make any sense to restrict this feature to paid users... it's running on local machines so is no cost to FF.
This renders FF a non starter full stop because the Web based workflow FF is far too slow and is really cumbersome having to reload and then expiring all the time.
