I prefer to use Firefox with WordPress when coding. I use an important plugin that gives me SCSS fubctionality that used to work without issue in Firefox until recently. The problem is conflicting keyboard shortcuts, namely tab selection "command + option + up arrow", and "command + option + down arrow" (on a Mac). I would like to reassign them, or better yet, set them to "false" as i never use the feature. I have tried many suggestions online, and none are working. Any help solving this would be much appreciated. Thank you.
