Where did it go wrong? Rated 4 out of 5 stars
I used to love this but the update to 2.15 makes it feel like malware. Not only did it add a new search engine and make it the default now everytime I start Firefox I have two totally pointless toolbars at the top. One for page zoom and one for HTML validation.
Mozilla should consider removing this from the add ons site if this behaviour is not rectified and soon.
