i really love this extetion

Nice idea, but some sites it literally freezes Firefox and brings up a "this extension is making Firefox slow" dialog.

Performance needs to be radically improved.

"Script from this extension causes Waterfox to slow down" and the CPU goes 100% for no obvious reason. No, thanks, moving on to the next extension.

Absolutely horrible. Runs scripts at the background to darken the pages, where a simple CSS-Edit shouldn't take minutes to adjust. Feels like having the worst VPN running in the background while scrolling a website.

诶，cpu带不动，太卡了

the best extension for coloring webpages with many customiziations,but slows down a little bit my computer.
