You appear to be using Firefox 113.0.2 That specific version makes me think you are using a old version of a Linux distro like Mint 19.3 as Firefox 113.0.2 was the last Firefox package update for it when it was made EOL with no more software updates through the official repositories. If you are using an old version of a distro like Mint 19.3 or an flavour of Ubuntu that ended about same time then you need to update to a current version of your Linux distro or another supported distro version to get packages updates support which can include Firefox package updates.. Or you can in meantime run the Firefox Linux tarball from Mozilla. I suggest perhaps using the Firefox 140.5.0esr over the current Firefox 145.0.1 Release. https://www.firefox.com/download/all/desktop-esr/ Wherever you put the extracted Firefox tarbal folder, make sure it has read/write permissions for the user so you can get internal Firefox updates from Mozilla. An easy way is to have Firefox folder in Home.
