this works, but upon checking my task manager. I found that this took too much cpu resources. Check your task manager and you will see the same thing

POWER HOG. Firefox goes from 5% cpu to 200% CPU consumption when this is toggled on. See other one-star review, which gives same reason. Maybe, just maybe, there may be some speed boost, but it is not noticeable. But the CPU cycles this takes is ridiculous. Disabled/Deleted.

This extension changes my firefox (and 4 others that I personally know) on both my desktop and laptop to use a constant 20% or more of the total CPU (my desktop is a 8 core I7 so that's a lot of CPU). I have no idea what it's doing or thinks it's doing but disabling sends firefox back to between 0% and 0.3% busy immediately.
