Great extension for an absolutely amazing product! I use buboflash daily and for me it is an essential tool in helping learn new materiel fast and retain the knowledge long-term. I also want to give special praise to Piotr Wasik, for putting so much time and effort into buboflash. He not only has put out a great, free tool for learning, but does a superb job maintaining it. I recently found a bug with buboflash (extremely rare occurrence) and after emailing Piotr, he put out a fix within an hour or so. Absolutely amazing! Even the top paid products don't provide this level of support and maintenance. Thank you Piotr and keep up the great work.

Amazing Extension! After many years waiting for a way to effectively incorporate article reading with Flashcards, this extension finally does the trick. It also add extended capability to PDF annotations, not to mention the tons of storage for a free service. One more gem of the Open Source World. Thank you!

Incredible app for productivity and accelerated learning... better than any of the popular spaced repetition programs out there, including Supermemo and Anki. I love the ease of use, and its use of incremental reading.
