/jp/ - Otaku Culture

Anyone know if there are any browser add-ons out there which can replicate what LingQ does where it highlights known words and words that you've seen before in a text? I feel like it would help a lot to cut down my overuse of Rikaichamp and make me pay more attention to the words I'm reading.

If not, I'm thinking of dropping Rikai altogether and switching to manual look-ups via the epwing version of JMDICT + qolibri because I feel like my overuse of Rikai and dependence on it to de-conjugate words and stuff is really becoming a barrier to my learning and vocabulary acquisition.

Where does the DJT Library maintainer get all these digitized LNs from?

Nobody seems to upload them to Nyaa and I can't imagine for a minute that he/she bought all these thousands of volumes him/herself. They don't show up on those raw manga/LN blogs either.
