Review for Babylon Dictionary Word Search by avada
Rated 2 out of 5 stars
This can't function with e10s enabled. Which is already the case for small fraction of users on stable. Soon it'll be enabled for everyone.
It's a shame, I liked this. But I can't use it ever since I set FF to use multiple proccesses. (a year or two now.)
