You appear to be using the old Firefox 96.0 on a Linux distro. https://support.mozilla.org/en-US/kb/install-firefox-linux Note if you are using a package build of Firefox and your version of Linux distro is not longer getting supported with package updates then that can explain why you have a old version of Firefox. You can either update your Linux distro to a current version or you can try the Firefox for Linux tarball from Mozilla https://www.firefox.com/download/all/desktop-release/linux64/ as it will get internal updates from Mozilla. Btw Mozilla no longer supports 32-bit Linux distros as of Firefox 145.0 though if you do have 32-bit Linux then you can use the Firefox 140 ESR til Sept 2026.
