I bought the Little Genie Magic Bobbin Washers a few years ago when I first started free motion quilting. They're a 12 pack of little silicone discs that just sit in your bobbin case and help the bobbin spin smoothly, especially when changing the direction of stitching at high speeds. I am not entirely certain that they help a bunch, but I will say that I rarely have issues with my bobbin thread since I started using them and followed the next tip I have for you below.
The bobbin washers are fairly cheap and last forever. The biggest thing is making sure you don't lose the tiny things! I've had the same on in my bobbin case for at least two years. Just set it in the case and forget about it. You can order a pack and split the cost with several quilters too.
The second tip for bobbin issues is to make sure you are using quality bobbins. My local Janome dealer sells generic bobbins unless you specifically ask for Janome bobbins. I make a point of buying the red Janome Cherry Blossom Bobbins when I can find them for my Janome and make sure I use them when free motioning. This helps me identify quilting thread from sewing thread too.

There are cheaper bobbins you can use, but I find that some have rough edges from when the plastic is molded into the bobbin shape. Plus, there seems to be a different type of plastic used for the Janome bobbins than the generic bobbins. It seems smoother and a teensy tiny bit softer. Janome bobbins will have a J on the shaft of the bobbin. This is covered by thread if already wound, so another identifier is a U shaped indention around one of the holes for the thread tail.
(Gee, I need a manicure!)
I am speaking here to Janome owners, because that is what I know, but I am sure that this could apply to other models and I know that generic bobbins are easy to come by. If you are having bobbin snarls, it might be worth finding better bobbins for your machine and/or checking to make sure the bobbin isn't damaged in some way.
On a personal note, my step daughter just made me a grandmother! So we'll be leaving town soon to visit her and the blog may go a bit quiet.
