Date/time input on website question

I have to use a specific booking system for work, in chrome it allows me to type in the date or time, and the site registers me doing it. In Firefox I have sliders for time or have to click on the calendar popup to get the date. I have spoken to the support from the booking system and their solution is use chrome. I am clueless about this stuff, is there anything I can do to improve this on my end in Firefox desktop? (It works fine on mobile) Thanks in advance!
