this trash Adaptive Tab Bar Colour by Eason ruin my css, and after uninstall this my firefox still flickering

非常好用且美观的插件，要是手机版的firefox也能兼容就好了！！！！

It's a neat trick to perform, but it's a terrible idea. I was under the impression it would change each tab to it's respective web page background, so I could quickly spot which tab to switch to. Instead of changing the entire theme of Firefox, just change individual tab colors. That would be a great idea. I'm coming back to update my rating as soon as that update takes place.

It works perfectly!!
