Having recently switched to Chrome (100 %) I find its handling of RSS Feeds to be poor. Let me illustrate -
So I install this extension for auto subscribing to RSS feeds (Link). This page says "okay I am now subscribing to the feed that I wanted". However even after checking the box above, it automagically forgets that "yes I had indeed asked you to remember that I want to subscribe to all feeds via Google Reader ONLY".
Now this screen says "You are not subscribed to this feed yet". I would swear that I indeed did that before (in the screen above).
