Often while surfing web sites it's common to encounter mistyped links like http://http//, mainly in forums, blogs and such. This extension automatically translate those mistyped links in valid ones using regular expressions. The add-on comes with 2 default rules whose purpose is to convert those urls I already mentioned above (http://http//) and the ones which are obfuscated in the form of hxxp:// instead of http:// to avoid being referrals of other websites. Custom rules are usable as well, they can be added through the interface accessible from Tools -> QuietUrl Options.
The extension can also automatically convert urls typed in text areas and obfuscate them replacing the http:// in hxxp:// when posting on forums; supported forums are phBB, invision and vBullettin but probably others already are because the check is only made on fields name and a lot use the same name attribute (like name="message" or name="post").
Also, the add-on automatically creates clickable links when hovering on a textual url with the mouse cursor. You can disable this through the preference window.
Additionally, a new interesting feature has been added, called SmartUrl, which is basically a very specialized version of AutoUrl. What it does is it recognizes url patterns for query strings and makes them clickable if some of the elements of the query string match with those in the URL of the current document.
To make things a bit more clear on how this last feature works: it's common in YouTube (I'm chosing YouTube as an example) to encounter comments that references other videos (that are on YouTube as well) in this form "Yes, this looks very similiar to: watch?v=AAAAAAA". The reasons for these kind of shortcuts are both to avoid being marked as spam and for readability/clarity of the message. Now with QuietUrl it is possible to just hover on that partial url and it will become clickable like every other AutoUrl generated urls.
Lastly another feature has been added that allows users to fast-select sub-paths in the directory tree of a url in the url bar when moving the mouse over the url bar while keeping CTRL and/or ALT keys pressed or none of them.
