Which macro? Both? My old versions worked fine for me, but I just edited my last post to replace them with new versions that use the %FrontBrowser% token instead of the one for the frontmost application, and replaced the KM actions for Chrome with @ccstone's script for closing the left Chrome tab, so feel free to try those instead. If the close all left tabs macro still doesn't work for Chrome, try replacing the script in that one with @ccstone's corresponding script there as well.
