sometimes annoying behavior Rated 3 out of 5 stars

NewsFox is the best feed reader out there as far as i'm concerned, but it's not perfect

it is way too strict when parsing feeds and this often results in the feed not being displayed at all, replaced instead with "The feed url is invalid. Check to make sure the URL is correct.", while the same feed displays fine in FF itself. this is particularly annoying because it is the INFORMATION in the feed that should be paramount, not whether the feed is valid.

another little issue is that it does not remember across sessions if the feed tool-bar was hidden
