Rated 5 out of 5 stars

Simply the best.
Sometimes I tryed use IE or Chrome and ever I back because they don't have something like NewsFox.

For my only a suggestion: Possibility of change screen distribution. I would like three vertical panes...

Congratulations!!

This review is for a previous version of the add-on (1.0.8.4.4.1-signed). 

If you mean like the French flag, separating lines vertical, then check options > general > horizontal panes.

If you mean like the Spanish flag, separating lines horizontal, then you're currently out of luck.
