It will be better if this extension has a option for setting images quality

CPU went to overdrive with this add-on. Took me a while to find this culprit.

This is very good and working well.Thank you!!!

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.

Very nice Tool. Indeed speed thinks up while browsing ;-)
