Mojave is the latest version of macOS but when it was released it was extremely buggy. They still stuggle with some strange issues like radio buttons and check boxes not displaying properly on some web sites. Therefore, as of this writing on March 9, 2019, we recommend that you DO NOT UPGRADE TO MOJAVE.

If you have already upgraded or purchased a computer with Mojave, you can try to fix the dropdown issue using this Chrome extension. Just install it into your browser.

There is a new beta release of Mojave 10.14.4 Beta 4 that came out the first week of March. We’re hopefully this may eliminate the issues, but in general, we do not recommend upgrading as we cannot fix these issues with macOS.

If you have an issue preventing use of the browser and the extension above does not fix it, you can roll back your macOS using these instructions.
