overall, excellent Rated 5 out of 5 stars

This feed reader is excellent. I used Brief, but that seems to have stopped being developed. This is the only acceptable replacement and I like it.

1. wish there was a way to change font size
2. wish checking delay slider went from 1-60 minutes instead of 1-20
3. nitpick, but I wish the number that showed up in the toolbar icon looked better

This review is for a previous version of the add-on (1.2.1-signed). 

Thank you for the review.

1. Changing font size in feed content is done and will be available in the next release
2. i will check if it works
3. i don't know what do you mean by "looking better" (you will soon be able to hide the unread count in the toolbar button)
