32-bit Chromium has not been updated by users for a long time, and 64-bit Chromium has not been updated for nearly a year, because these software packages are contributed by users, so I give you two Suggestions: 1. I suggest you use Firefox directly. 2. I suggest you change to a 64-bit system, then download the latest Chromium source code, and then compile it by yourself.
See Juanito for a link on how to compile.
Note that Chromium is only available in 64-bit, so you'll need to upgrade to 64-bit first
