/* --------- Note ---------
TO INCLUDE SITES (only Greasy Fork and OpenUserJS are initially included):
Go to Add-ons - User Scripts (Ctrl+Shift+a/Cmd+Shift+a on Firefox Windows/Mac)
Click on the Script's Option
Under User Settings Tab, Add Included/Excluded Pages that you want the script to run on
Click OK
Note from erosman: If you find that another script clashes with this script, set Text Highlight and Seek to Execute first.
Go to Add-ons - User Scripts ('Ctrl+ Shift + a' on Firefox)
Right Click on the Script
On the context menu click: Execute first
On Add-ons - User Scripts, you can also Click on the Execution Order (top Right) and
change the execution order so that Text Highlight and Seek runs before those scripts that clashes with it.
