It was closed as off-topic by several users with the following reason:
"Questions seeking resources or advice about learning Japanese are off-topic here, but you may find our list of resources for learning Japanese helpful." – istrasci, naruto, Flaw
We try to keep our site focused on questions about the language itself, not about learning methods or programs to help with learning.
Since the question was clearly off-topic and had no chance of being reopened, I removed it rather than leave it "on hold". To be honest, it read more like an advertisement for your Chrome extension than a real question; it wasn't really written in a way that invited answers from other users.
The link to your question can be found below, although not everyone will be able to see it:
