This is a vital app for using reddit.
However, I suggest an Improvement: in the extensions drop down menu, I would like an ON/OFF switch.
I often find myself wanting to browse some subs in new reddit and others in old (I like big pics and I cannot Lie) nad I need to open the complete add-ons page and scroll down to this one just to switch between old and new.
Until implemented, this Add-on has a 4/5 from me. Excellent work, small gripe.
