The current version of Firefox v144 is still compatible with macOS 10.15 Catalina, but I think this will be last version of Firefox that will be compatible:

That is your best option for a web browser.
Chrome dropped support for Catalina over a year ago. If you insist on a Chromium based browser, then my other post here has a link to one of the last versions of Vivaldi with support for Catalina (you will need to do your own research to find a link to an outdated version of Chrome or any other browser....they don't make it easy):

FYI, in a couple of years when v144 of Firefox can no longer access some parts of the Internet, you may want to look into installing Linux Mint on that old laptop. Linux is an up to date non-Apple OS which has access to the popular web browsers (Firefox, Vivaldi, Brave, Chrome) as well as LibreOffice (free open source office suite like MS Office) and many other free open source apps in Linux Mint's software repository. Linux is not for everyone, but it is a great way to extend the useful life of older computer if you are willing to learn a new OS.
You can test drive Linux Mint by booting the Linux Mint USB installer and selecting the "Live" option (this won't hurt your current macOS installation)....performance will be slow because it is booting from a slow USB stick, performance will be good (probably better than macOS itself) when installed to the internal HD/SSD (or even an external HD/SSD). This will allow you to see what Linux Mint will look like and the default apps which are installed. There is more software available to be installed from the Linux Mint software repository.
If you decide to install Linux Mint to the internal HD/SSD, then make sure to first create a bootable macOS Catalina USB installer now while you still can just in case you encounter issues using Internet Recovery Mode later.....make sure it will boot the laptop. And make sure you have transferred any important files from the laptop before installing Linux Mint.
