Great add-on for learning Japanese. But can you make it turned on by default. It is a pain to turn it on everytime

I seem to have to toggle it on or off and back on but other than that I find this to be really helpful.

The Standard and Leading Program in it's class, very technical, designed to be turned on and turned off when needed, there is a setting that turns off highlighting text, which may cause an end to some bad comments about deleted text which absolutely can happen if your typing in japanese and come across your cursor, highlight your text and the program trys to read what you wrote, if you keep typing over highlighted text, well, you can see the potential for some incidents there. but there are settings for that, or just turn off when not using. as well many various options to suit your style. As well, it understands Japanese not bad.

Pretty great, but I never thought I'd see something that runs faster in Firefox than Chrome. It takes so long to activate that I wonder if it's trying to load at all. If I have it turned on and I then toggle off/on on a single tab it should be basically instant since it's already loaded everything and shouldn't need to again.
