Firth, 23, has been with the Light Blues since last January after signing an 18-month upon arriving from English National League side Barrow, but he has featured in just one game so far.
The Rangers man came on as a substitute for Wes Foderingham on the final day of last season away to Kilmarnock in May, and has mainly being a training ground goalkeeper.
Nevertheless, the Ibrox outfit deemed it fit to hand him a new deal and he will continue to provide back up for the wantaway Foderingham and Allan McGregor.
Rangers fans can’t believe the club’s decision, and here is how they reacted to Firth extending his contract on Twitter:

Firth spent eight years in the Liverpool academy before spending three years with the senior team prior to his departure in 2018, but he wasn’t able to make any appearance.
The goalkeeper obtained his coaching badges during his time with the Reds’ academy, and due to financial constraints at Chester, he acted on occasion as coach for loanee goalkeeper Will Jaaskelainen.
