The version of Firefox installed on the remote Windows host is prior to 129.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2024-33 advisory.

  - Incorrect garbage collection interaction could have led to a use-after-free. (CVE-2024-7530)

  - Insufficient checks when processing graphics shared memory could have led to memory corruption. This could     be leveraged by an attacker to perform a sandbox escape. (CVE-2024-7519)

  - Select options could obscure the fullscreen notification dialog. This could be used by a malicious site to     perform a spoofing attack. (CVE-2024-7518)

  - A type confusion bug in WebAssembly could be leveraged by an attacker to potentially achieve code     execution. (CVE-2024-7520)

  - Incomplete WebAssembly exception handing could have led to a use-after-free. (CVE-2024-7521)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
