hope to add a key,but can not auto clear record after again

I like this add-on. I like the look of the highlighted words and the fact that it will highlight parts of words.
Is it possible to upgrade the add-on so that it will stay 'On' unless you click 'Off'?
It's a pain to always have to click 'On' everytime you change webpages. Also, when you click 'Show more' comments under a Youtube video, you have to click the 'On' button everytime.

Absolument inutile. Ne remplit pas les fonctions promises. Perte de temps

DOES.
NOT.
WORK.

нет возможности включить в автоматическом режиме поиск. обязательно нужно нажать кнопку ON

perfect, it helps me alot
