Convert Mixamo rig bone names (as imported to Blender via FBX) to standard Blender bone names. This is especially use if your mesh uses the 'mirror' modifier. 1 - Backup your Blend. 2 - In action editor disconnect any animation connected to the rig. 3 - Paste the script in a text window and select "run script". 4 - Notice that all bone names are now changed.
