This answer wasn't easy to find and once I did find it there wasn't a fix other then to turn off Actual Window Manager. I found the fix if you want to continue using Actual Window Manager: # Open Up Settings in Actual Window Manager # Select: Window Settings Tab # Add New Window Rule # In the "Target Window" Settings for this rule select Firefox as the "Program" # Go to the "Start-up" Settings beside "Target Window" Settings # In the "Options" area check the box "Block premature appearance of window" # Check the box "COMPATIBILITY MODE" STEP #7 SOLVES THE PROBLEM Profit!
