Old version of Firefox (45.0.2) is invisible on MacBook M1

more options

Hello, on my project we have a requirement to support a specific version of Firefox, which is 45.0.2. I downloaded it from ftp.mozilla.org, but when I'm launching browser, it just displays an invisible window with shadow border (see screenshot below).

My device: MacBook Pro 14 2021 M1 Pro, OS X Ventura (13.0.1)

I guess it has something to do with an M1 chip, but is there any way to fix it?

Please tell the people on your project that very few customers would be using this old version of Firefox (from 2016) and they should not waste time and money figuring out how to support it.
