Hi @Russ_Thomas,
KS v7.9 and previous come with geckodriver v0.23 so it may not compatible with Firefox v84 on your machine but the embedded gecko driver is in our expectation. As I mentioned in this post Black screen when using Spy - #8 by duyluong, we are planing to update geckodriver version in our major releases (maybe in v8.0).
The reason why we don’t update geckodriver immediately like chromedriver because since v0.25, geckodriver needs VC++ binary to run on Windows machine so we need more times to test it with various distributed systems.
