Hi

Please appreciate that the version of Firefox that you are using has not been supported or received security and maintenance updates for about three years.

You may have to look into getting a device that has a supported operating system.

Try to change your user agent to

 Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:130.0) Gecko/20100101 Firefox/130.0

Besides updating your macOS to at least 10.12 if your hardware supports it so you can run the still supported Firefox 115 ESR. It is currently at 115.18.0esr and will be updated till Fx 115.21.0esr in March 2025 unless Mozilla decides in early 2025 to extend updates again. https://support.mozilla.org/en-US/kb/firefox-users-macos-1012-1013-1014-moving-to-extended-support

Firefox 116.0 and later including current Firefox Release requires macOS 10.15 or later to run.
